Overview Captive portals provide secure authenticated or un-authenticated access to Wireless LANs using standard Web browsers. Captive portals function by capturing and redirecting a wireless user’s Web browser session to a landing page where the user must enter their credentials, accept terms and agreement or supply specific information before being permitted access to the Wireless network. Captive portals can be utilized for multiple applications including guest / visitor access, hotspots or BYOD and are now common in most enterprise environments. Captive portals have become a very popular means for authenticating guest / visitor users as they provide administrators with the means for implementing authentication without deploying 802.1X or distributing pre-shared keys. More recently captive portals have also become a popular mechanism for on-boarding devices for secure guest access applications by re-directing corporate or guest / visitor user’s web-browser sessions to a service which can quickly provision the device to connect to a secure network. 1.1 Captive Portal Policies In WiNG 5 the captive portal operation is controlled using captive portal policies which are assigned to Wireless LANs as well as the WiNG 5 devices that are performing the capture and redirection. Each captive portal policy defines: 1. The WiNG 5 devices that are to perform the capture and redirection. 2. The captive portal type (authenticated vs. non-authenticated). 3. The captive portal connection mode (HTTP or HTTPS). 4. The maximum number of simultaneous users per Access Point. 5. Login, welcome, failed and terms of condition web page source and customization. When enabling captive portal services in a WiNG 5 network, there are three main choices that need to be made. The first choice is to decide which WiNG 5 devices are to perform the captive portal capture and redirection. The second choice is to determine if and how the captive portal authenticates the users, a terms and conditions page is presented. The third choice determines where in the network the captive portal pages are hosted. Captive portal pages can be hosted on the Wireless Controllers, Access Points , external HTTP server or an external appliance providing secure guest access provisioning. The choice as to how authentication is performed, where the captive portal pages are hosted and which devices perform the capture and redirection will largely depend on the specific type of deployment. This guide aims to provide examples for various common captive portal deployment types for campus, and distributed deployments. The appendix provides additional information for customizing pages and provisioning the captive portal policy for secure guest access applications. The following section provides a detailed overview of the key parameters that can be defined for each captive portal policy. Page 4 WiNG 5.X How-To Guide – Captive Portals 1.1.1 Captive Portal Server Mode The server mode parameter determines which WiNG 5 devices are performing the capture and redirection. Capture and redirection can be performed on a Dependent / Independent Access Point or on a RFS X000 Wireless Controller. The WiNG 5 captive portal implementation is very flexible as it allows the captive portal services to reside anywhere within the WiNG 5 network. For example the capture and redirection can be performed directly by the Access Points at the edge of the network, centrally on the RFS X000 Wireless Controllers managing the Access Points or on dedicated RFS X000 Wireless Controllers deployed within an isolated network or DMZ. Server Mode Description Internal (Self) Capture and redirection is provided by the Access Point that is servicing the captive portal enabled Wireless LAN. Centralized Capture and redirection is provided by a designated RFS X000 Wireless Controller on the network defined using an IPv4 address or hostname. The RFS X000 Wireless Controller can either be managing the Dependent / Independent Access Points or be a dedicated device deployed over the intermediate network. Centralized Controller Capture and redirection is provided by a cluster of RFS X000 Wireless Controllers that are managing the Dependent / Independent Access Points using a virtual hostname. Table 1.1.1 – Captive Portal Server Modes 1.1.1.1 Internal (Self) The Internal (Self) server mode enables capture and redirection on the Dependent / Independent Access Points servicing the captive portal enabled Wireless LAN. The Internal (Self) captive portal server mode is typically enabled for deployments with: 1. 2. Centrally managed remote Dependent / Independent Access Points using Level 2 MINT links: a. Wireless LAN traffic is locally bridged by the Access Points to an isolated VLAN that is serviced by an Internet router at each remote site. b. Wireless LAN traffic is locally routed by an AP6511 or AP71XX series Access Point directly connected to the public Internet. Standalone or Virtual Controller based deployments using Independent Access Points. The Wireless LAN traffic is locally bridged by the Access Points to an isolated VLAN that is serviced by an Internet router at the site. When enabled each remote Access Point servicing the captive portal enabled Wireless LAN will perform the captive portal capture and redirection internally. The Wireless LAN users are mapped to a locally bridged VLAN for which each Access Point has a Switched Virtual Interface (SVI) defined. The SVI can either have a static or dynamic (DHCP) IPv4 address assigned. The capture, redirection and presentation of the captive portal pages are performed using the SVI on each Access Point the wireless device is associated to. When a wireless device associates to a captive portal enabled Wireless LAN, the device will receive its IP address from the local Internet router or from a DHCP server integrated directly into the Access Point. The VLAN is either 802.1Q tagged out the Access Points Gigabit Ethernet interface or is internally routed and NATed to the Internet. Upon launching a web-browser the devices HTTP session will be captured and re-directed by the SVI on the Access Point to captive portal pages either hosted locally within the Access Point or externally on a HTTP server. Page 5 WiNG 5.X How-To Guide – Captive Portals 1.1.1.2 Centralized The Centralized server mode enables capture and redirection on a specific RFS X000 Wireless Controller within the WiNG 5 system when traffic is being tunneled to the RFS X000 Wireless Controller managing the Dependent / Independent Access Points. The capture and redirection can either be provided by the RFS X000 Wireless Controller that is managing the Access Points or a dedicated RFS X000 Wireless Controller deployed in an isolated network or DMZ. The Centralized server mode is typically enabled for deployments with: 1. Branches with a single RFS X000 Wireless Controller managing Dependent / Independent Access Points. 2. Campuses with a single dedicated RFS X000 Wireless Controller deployed in the data center / DMZ that is providing the captive portal capture and redirection. The Dependent / Independent Access Points are managed by a separate pair of RFS X000 Wireless Controllers. The Centralized server mode requires the IPv4 address or hostname of the RFS X000 Wireless Controller that is performing the capture and redirection to be defined in the captive portal policy. The capture and redirection can either be performed locally on the RFS X000 Wireless Controller that is managing the Access Points or a dedicated RFS X000 Wireless Controller deployed elsewhere in the network. The only requirement is that the RFS X000 Wireless Controller performing the capture and redirection must be reachable via the MINT protocol. The Wireless LAN users are mapped to a tunneled VLAN for which the designated RFS X000 Wireless Controller that is performing the capture and redirection has a Switched Virtual Interface (SVI) defined. The SVI can either have a static or dynamic (DHCP) IPv4 address assigned. The capture, redirection and presentation of the captive portal pages are performed using the SVI on the designated RFS X000 Wireless Controller. When a wireless device associates to a captive portal enabled Wireless LAN, the device will receive its IP address from the local Internet router or a DHCP server operating on the designated RFS X000 Wireless Controller. The tunneled VLAN is typically assigned to one of the designated RFS X000 Wireless Controllers Gigabit Ethernet interfaces or is internally routed or NATed to the Internet. Upon launching a web-browser the devices HTTP session will be captured and re-directed by the SVI to the captive portal pages either hosted locally on the designated RFS X000 Wireless Controller or externally on a HTTP server. Note: No redundancy is provided with the centralized option as only a single device can b e defined. If redundancy is required the centralized controller option must b e utilized. Page 6 WiNG 5.X How-To Guide – Captive Portals 1.1.1.3 Centralized Controller The Centralized Controller server mode enables capture and redirection on a cluster of RFS X000 Wireless Controllers managing Dependent / Independent Access Points when redundancy is required. The capture and redirection is provided by one of the RFS X000 Wireless Controllers in the cluster that is operating as the designated forwarder for the tunneled VLAN. The cluster can be configured as active / active or active / standby as required. The Centralized Controller server mode requires a non-resolvable virtual hostname to be defined in the captive portal policy which is shared between the RFS X000 Wireless Controllers in the cluster. One of the RFS X000 Wireless Controllers will become the designative forwarder for the tunneled VLAN and during normal operation will provide capture and redirection. If the RFS X000 Wireless Controller that is elected as the designated forwarder fails or is taken down for maintenance, the second RFS X000 Wireless Controller will become the designated forwarder and provide the capture and redirection. The Wireless LAN users are mapped to a tunneled VLAN for which the RFS X000 Wireless Controllers in the cluster Switched Virtual Interfaces (SVI) defined. The SVIs can either have a static or dynamic (DHCP) IPv4 address assigned. The capture, redirection and presentation of the captive portal pages are performed using the SVI on the RFS X000 Wireless Controller that is the designated forwarder for the tunneled VLAN. When a wireless device associates to a captive portal enabled Wireless LAN, the device wil l receive its IP address from an external DHCP server typically running on the Internet router or firewall. The tunneled VLAN is typically assigned to one of the designated RFS X000 Wireless Controllers Gigabit Ethernet interfaces to a local Internet router / firewall. Upon launching a web-browser the devices HTTP session will be captured and re-directed by the SVI to the captive portal pages either hosted locally on the RFS X000 Wireless Controllers or externally on a HTTP server. In WiNG 5.3 and above the centralized controller mode can also be utilized to forward captive portal traffic to a cluster of RFS X000 Wireless Controllers deployed in an isolated network or DMZ. This special use case provides redundancy by leveraging VRRP to determine which RFS X000 Wireless Controller in the isolated network provides the captive portal capture and redirection. The RFS X000 Wireless Controllers managing the Dependent / Independent Access Points tunnels the traffic to the RFS X000 Wireless Controllers in the isolated network which perform the capture and redirection. Authentication (if required) is provided by the RFS X000 Wireless Controllers managing the Access Points. Page 7 WiNG 5.X How-To Guide – Captive Portals 1.1.2 Connection Modes Each captive portal policy allows administrators to define the connection mode for the captive portal which can be HTTP (default) or HTTPS. The choice of which mode to use will depend on how the captive portal is being utilized: 1. The HTTP connection mode is typically utilized for captive portal deployments when no credentials are exchanged over the captive portal enabled Wireless LAN. A typical application for HTTP is when open access is being provided to users who have to accept and terms and conditions page before being permitted access to the network. 2. The HTTPS connection mode is typically utilized for captive portal deployments when credentials are exchanged over the captive portal enabled Wireless LAN. A typical application for HTTPS is guest / visitor access when users have to enter valid credentials before being permitted access to the network. As the captive portal enabled Wireless LAN typically has no encryption, the HTTPS mode is useful for securing credential exchanges over the Wireless LAN. When enabled the Dependent / Independent Access Point or RFS X000 Wireless Controller will use a signed certificate installed in the default or user defined Trustpoint to secure the web-browser sessions. The user’s web-browsers will be captured and redirected to a landing page using HTTPS port 443. As the HTTPS connection mode utilizes PKI and trust to secure the web-browser sessions, a publically signed certificate is typically deployed on the Dependent / Independent Access Points or RFS X000 Wireless Controllers providing the capture and redirection. By default a self-signed certificate is installed on each WiNG 5 device which is assigned to the HTTPS service used for capture and redirection, however as the users web-browsers or operating systems will not have the corresponding CA root CA certificates the user’s web browsers will display a certificate error when the HTTPS connection is made. To overcome these certificate errors a public or privately signed certificate that the users web-browsers or operating system trusts must be installed on the WiNG 5 devices providing the captive portal capture and redirection. For enterprise deployments this can be a certificate signed by the enterprise private certificate authority where the root CA certificates are pre-installed on the managed devices. For public or guest / visitor applications the certificates are typically signed by a well-known public certificate authority that the web-browsers or operating systems already trust. Most current operating systems and web-browsers have root CA certificates for popular certificate authorities pre-installed. HTTP mode is useful for open access captive portal applications that require terms and condition pages to be presented to users before providing access to the network. As no credentials are exchanged over the captive portal enabled Wireless LAN no security is required. When enabled the users web-browser sessions will be captured and re-directed to the terms and conditions landing page using HTTP port 880. The user must agree to the terms and conditions page before being permitted access to the network. No public or privately signed certificates are required. Page 8 WiNG 5.X How-To Guide – Captive Portals 1.1.3 Access Types Each captive portal policy supports an Access Type which determines how the user session is authenticated. WiNG 5 supports a number of different Access Types to support various different captive portal deployments. For example the RADIUS type is typically enabled for guest / visitor access where user credentials are authenticated against an internal or external RADIUS server. The Logging or No Authentication types are typically enabled for public Hotspot deployments when a terms and conditions page are displayed to the user for which they must agree before being permitted access to the network or secure guest access applications when the session is captured and redirected to an external server for provisioning. The Custom type is designed for deployments with a customized RADIUS backend which can authenticate users using user-supplied information such as a name, loyalty ID, email address or phone number. This type of deployment typically utilizes a customized RADIUS server which can authenticate sessions using information other than usernames / passwords. Access Type Description Custom Authenticates users against a customized back-end RADIUS server using custom user supplied information. Logging Generates a logging record and permits access. RADIUS Authenticates users against RADIUS using username and password. No Authentication No authentication is performed. Table 1.1.3 – Access Types 1.1.4 Web Page Source Captive portal pages can be hosted internally on an Dependent / Independent Access Point, RFS X000 Wireless Controller or on an external HTTP server. The captive portal supports the following page types: 1. login.html – Is presented to user’s web-browser when the RADIUS type is enabled. 2. welcome.html – Is presented to the user’s web-browser upon successful RADIUS authentication or when the Logging or No Authentication types are enabled. 3. fail.html – Is presented to the user’s web-browser upon a failed RADIUS access attempt. 4. agreement.html – Is presented to the user’s web-browser when the user must agree to the defined terms and conditions. The captive portal pages can be system generated or fully customized. Each captive portal policy supports three different web-page source options that determine if a system generated or customized pages are used and if the pages are hosted locally on a WiNG 5 device performing the capture and redirection or externally on a HTTP server. 1.1.4.1 Internal The Internal (default) source option will create system generated login, welcome, fail and agreement pages on the WiNG 5 devices performing the capture and redirection. The system generated pages support minimum customization which is performed within the captive portal policy. The system generated pages are created as soon as the captive portal policy is assigned to the WiNG 5 device using a profile or override. Page 9 WiNG 5.X How-To Guide – Captive Portals The system generated pages are automatically installed into a subdirectory under flash:/hotspot/ on the WiNG 5 device. The subdirectory name will match the captive portal policy name assigned to the device. If multiple captive portal policies are assigned to a device, a sub-directory for each captive portal instance will be created on the device. 1.1.4.2 Advanced The Advanced source option allows administrators to upload customized login, welcome, fail and agreement pages into the WiNG 5 devices performing the capture and redirection. The Advanced source option must be selected when customized pages are being hosted on a WiNG 5 device. Using the Internal option and uploading customized pages will result in the customized pages over-written. Customized pages are typically based on the default system generated pages automatically created when the default Internal source option is selected. The system generated pages are downloaded from a WiNG 5 device to a TFTP or FTP server where they are modified using a standard HTML editor. The customized pages along with logos and other files are then uploaded onto one or more WiNG 5 devices. In WiNG 5.2.12 and WiNG 5.4 (and above), customized pages can be simultaneously uploaded to multiple Access Points using the captive-portal-page-upload command. Prior to these releases the captive portal pages had to be manually uploaded to each individual Access Point. This command allows customized pages and images had to be quickly distributed to multiple Dependent / Independent Access Points across multiple sites. The customized content is zipped into a TAR archive and then distributed. Note: The advanced source must b e selected whenever customized login, welcome, fail and agreement pages are b eing hosted on a WiNG 5 device. Failure to select this option will result in the customized pages b eing replaced with system generated pages. 1.1.4.3 Externally Hosted The Externally Hosted source option allows administrators to host customized pages on a centralized HTTP server or re-direct users re-direct users web-browsers to a specific URL or external portal. The Externally Hosted source option allows administrators to define specific URLs for the login, welcome, fail and agreement pages. The pages that are displayed will depend on the Access type defined in the policy. Externally hosted pages are useful for the following applications: 1. When customized pages are too large to be uploaded onto the WiNG 5 devices 2. When web-browsers need to be re-directed to specific URLs such as Intranet or public sites. 3. BYOD when external portals are utilized for on-boarding and authentication. 4. Paid access when external portals are utilized for billing and authentication. When captive portal pages are hosted externally, the captive portal users must be permitted access to the IPv4 addresses or hostnames where the redirect URLs reside. By default a captive portal enabled Wireless LAN will only permit DHCP, DNS and access to the internally hosted system generated or customizes pages and access to any other external site will be denied. To permit access to externally hosted content, a DNS Whitelist policy must be defined and assigned to the Captive Portal policy. The DNS Whitelist policy includes the IP address(es) or hostname(s) of one or more HTTP servers hosting the customized content. Once assigned captive portal users sessions can be re-directed to the permitted external hosts. Access to non-permitted hosts will still be denied. This capability is often referred to as a walled garden. Note: A DNS Whitelist Policy must b e defined when customized content is hosted on an external host. The DNS Whitelist policy permits access to specific hosts using IPv4 addresses or hostnames. Page 10 WiNG 5.X How-To Guide – Captive Portals 1.2 Wireless LANs Captive portal services are enabled on a per Wireless LAN basis. Each Wireless LAN is assigned to one or more Access Point radios typically using profiles. Each Wireless LAN defines the SSID name that is advertised to wireless devices, the users VLAN assignment, authentication and encryption options. Administrators can use captive portal authentication as a primary or secondary means of authenticating wireless users. Captive portal authentication is typically enabled on Wireless LANs with no encryption allowing guest / visitor users to connect to the network with minimum configuration. When used as a primary means of authentication, all wireless user’s web-browser sessions are captured and re-directed to the captive portal landing page. Depending on the captive portal configuration, the wireless users may be required to provide credentials or must agree to terms and conditions before being permitted access to the network. Captive portals may also be used as a secondary means of authentication when EAP , EAP-MAC or MAC authentication is enabled on the Wireless LAN and no encryption is enabled. When enabled as secondary authentication the wireless user’s web-browser sessions will only be captured and re-directed to the captive portal landing page if the EAP or MAC authentication fails. If EAP or MAC authenti cation is successful, the wireless users are permitted access to the Wireless LAN bypassing the captive portal. The VLAN configuration for the captive portal enabled Wireless LAN will vary based on the WiNG 5 deployment: Centrally Managed Branch Deployments – The guest / visor VLAN will typically be locally bridged by the Access Points. The Wireless Controllers managing the remote Access Points are removed from the data-path and 802.1Q tagging provides the separation of the private and guest / visitor traffic. Campus Deployments – The guest / visor VLAN will typically be tunneled to the RFS X000 Wireless Controllers managing the Access Points at the site. The RFS X000 Wireless Controllers managing the Access Points provide the separation of the private and guest / visitor traffic. Campus Deployments with Anchor Controllers – The guest / visitor VLAN will be tunneled to one or more RFS X000 Wireless Controllers deployed in an isolated network or DMZ via the RFS X000 Wireless Controllers managing the Dependent / Independent Access Points. The Wireless Controllers in the DMZ provide the separation of the private and guest / visitor traffic. 1.3 Switch Virtual Interfaces Switched Virtual Interfaces (SVIs) are a critical component to a captive portal solution as they allow the WiNG 5 devices to provide the capture and redirection of the wireless user’s browser traffic. Each WiNG 5 device that provides captive portal capture and redirection will require an SVI on the VLAN that the Wireless LAN traffic is mapped to. The SVIs can have a static or dynamic IPv4 address assigned. The SVI configuration for the devices will vary based on the WiNG 5 deployment: Centrally Managed Distributed Deployments – Each remote Access Points will bridge the Wireless LAN user traffic locally. Each remote Dependent / Independent Access Point will require an SVI and IPv4 address on the VLAN the captive portal traffic is bridged to. The SVIs are typically defined in the Access Point profile(s) and receive enabled for DHCP. Campus Deployments – The Access Points will tunnel the traffic to the RFS X000 Wireless Controllers managing the local Access Points. Each RFS X000 Wireless Controller managing Dependent / Independent Access Points will require an SVI and IPv4 address on the VLAN the captive portal traffic is tunneled to. The SVIs are typically defined on each RFS X000 Wireless Controllers as overrides with static IPv4 addresses assigned. Campus Deployments with Anchor Controllers – The Access Points tunnel the traffic to one or more RFS X000 Wireless Controllers in an isolated network or DMZ via the RFS X000 Wireless Page 11 WiNG 5.X How-To Guide – Captive Portals Controllers managing the Dependent / Independent Access Points. Each RFS X000 Wireless Controllers in the isolated network or DMZ will require an SVI and IPv4 address on the VLAN the captive portal traffic is tunneled to. Additionally a VRRP virtual IP address will be required for redundant deployments. The SVIs and VRRP virtual IP addresses are typically defined on each RFS X000 Wireless Controllers as overrides with static IPv4 addresses assigned. Page 12 WiNG 5.X How-To Guide – Captive Portals 2. Configuration Examples The following section provides step-by-step configuration examples for common captive portal customer deployments including centrally managed Access Points, campus deployments and campus deployments with anchor controllers. Each deployment scenario will provide an overview of the solution as well as example Captive Portal policy, Wireless LAN and SVI configuration. 2.1 Centralized Deployments In this example the remote Dependent / Independent Access Points are adopted and managed by a cluster of centralized NX9x00 Integrated Services Platforms using Level 2 MINT links . The remote Dependent / Independent Access Points are adopted and managed over VLAN 21 and communicate with the centralized Controllers over a private WAN / MPLS service via a local branch router. As no traffic can be tunneled to the centralized NX9x00 Integrated Services Platforms, the captive portal Wireles s LAN traffic is locally bridged by the remote Dependent / Independent Access Points onto an isolated guest VLAN 25. For capture and redirection each remote Dependent / Independent Access Points has an SVI on the guest / visitor VLAN which obtains an IPv4 address dynamically from a DHCP server operating on the Internet router / firewall connected to VLAN 25. The Internet router / firewall provides dynamic IPv4 addressing for the Dependent / Independent Access Points in addition to providing IP addressing and default gateway services for the guest / visitor users at the site. Figure 2.1 – Centralized Deployment Page 13 WiNG 5.X How-To Guide – Captive Portals 2.1.1 Captive Portal Policy A captive portal policy will be defined that enables captive portal capture and redirection on the Access Points and requires guest / visitor users to agree to terms and conditions prior to being permitted access to the Internet. The captive portal policy will be assigned to the Guest Wireless LAN as well as the Access Point profile. 1 Note: For this example the default terms and conditions page hosted on the Access Points will b e displayed. The content of the default terms and conditions page can b e modified to suit the customer’s requirements. Alternatively a customized terms and conditions page can b e defined and uploaded to the remote Access Points using the captive-portal-page-upload command after changing the Web Page Source in the captive portal policy from Internal to Advanced.

Using a profile each remote Access Point will be assigned the Captive Portal policy and will have the captive portal enabled Wireless LAN mapped to their 2.4 GHz radios. In addition each remote Access Point will have a Switched Virtual Interface (SVI) defined for VLAN 25 which will be enabled for DHCP. For isolation VLAN 25 will be also 802.1Q tagged out of the Access Points Ge1 interfaces. 1 Using the Web-UI select Configuration Profiles <ap-profile-name> Edit: Page 19 WiNG 5.X How-To Guide – Captive Portals 2 Select Interface Ethernet Ports ge1 Edit.

Page 22 WiNG 5.X How-To Guide – Captive Portals 2.2 Campus Deployments In this example the Dependent / Independent Access Points are adopted and managed by a cluster of RFS 6000 Wireless Controllers at the site using Level 1 MINT links. The Dependent / Independent Access Points are adopted and managed over VLAN 21 and communicate with the Controllers over a high-speed local area network. As this deployment utilizes Level 1 MINT links, the captive portal Wireless LAN traffic (VLAN 25) will be tunneled from the Dependent / Independent Access Points to the cluster of RFS 6000 Wireless Controllers at the site. For capture and redirection each RFS 6000 Wireless Controller in the cluster will include an SVI with a static IPv4 address on VLAN 25. For redundancy both RFS 6000 Wireless Controllers will be able to provide capture and redirection using a virtual hostname which is shared between the Controllers in the cluster. The local Internet router / firewall provides dynamic IPv4 addressing and is the default gateway for the guest / visitor users at the site. The guest / visitor traffic will be bridged to VLAN 25 where the Internet / firewall resides using 802.1Q tagging enabled on each RFS 6000 Wireless Controllers uplink port. Figure 2.2 – Campus Deployment Page 23 WiNG 5.X How-To Guide – Captive Portals 2.2.1 AAA Policy Each guest / visitor user will be authenticated by the integrated AAA server on the cluster of RFS 6000 Wireless Controllers. An AAA policy needs to be defined to tell the WiNG 5 system where to forward the authentication requests when a guest / visitor user provides their credentials on the captive portal login page. The AAA policy will be assigned to the captive portal enabled Wireless LAN. 1 Using the Web-UI select Configuration Wireless AAA Policy Add: 2 Name the policy then click Continue: Page 24 WiNG 5.X How-To Guide – Captive Portals 3 Set the Server Type to onboard-self then click OK, Exit then Exit again: 4 A AAA policy has now been defined: 5 Commit and Save the changes: Running-Configuration Changes: ! aaa-policy INTERNAL-AAA authentication server 1 onboard controller !

Page 47 WiNG 5.X How-To Guide – Captive Portals 2.3 Campus Deployments with Anchor Controllers In this example the Dependent / Independent Access Points are adopted and managed by a cluster of RFS 6000 Wireless Controllers in the private network using Level 1 MINT links. The Dependent / Independent Access Points are adopted and managed over VLAN 21 and communicate with the RFS 6000 Wireless Controllers over a high-speed local area network. The guest / visitor Wireless LAN traffic (VLAN 25) is tunneled from the Dependent / Independent Access Points to the cluster of RFS 6000 Wireless Controllers managing the Access Points. The guest / visitor traffic is then tunneled over static MINT links to a cluster of RFS 4000 Wireless Controllers in the isolated network that perform the captive portal capture redirection using a virtual hostname. User authentication is provided by the RFS 6000 Wireless Controllers managing the Dependent / Independent Access Points. This model allows the guest / visitor traffic to be completely isolated from the internal private network. Figure 2.3 – Campus Deployment with Anchor Controllers Note: This configuration example can also b e followed for deployments using a single RFS X000 Wireless Controller in the isolated network or DMZ. Page 48 WiNG 5.X How-To Guide – Captive Portals This deployment leverages Virtual Router Redundancy Protocol (VRRP) to provide redundancy for the captive portal capture and redirection on the cluster of RFS 4000 Wireless Controllers. VRRP is enabled on VLAN 25 on the RFS 4000 Wireless Controllers which use a virtual IP address and hostname to provide the captive portal capture and redirection. Each RFS 4000 Wireless Controller has a unique SVI defined on VLAN 25 and share a VRRP virtual IP address (one is master, one is backup). During normal operation the RFS 4000 operating as the VRRP master provides the capture and redirection services. To forward the captive portal capture and redirection traffic to the cluster of RFS 4000 Wireless, an SVI is defined on an isolated VLAN 125 on both RFS 6000 Wireless Controllers in the private network with their IP addresses set to the VRRP virtual IP address assigned to the RFS 4000 Wireless Controllers. The isolated VLAN is not extended between the RFS 6000 Wireless Controllers. These SVIs allow the RFS 6000 Wireless Controllers to redirect the captive portal traffic over MINT to the VRRP virtual IP interface in the isolated network. 2.3.1 RFS 6000 Wireless Controllers – Private Network 2.3.1.1 AAA Policy Each guest / visitor user will be authenticated by the integrated AAA server on the cluster of RFS 6000 Wireless Controllers. An AAA policy needs to be defined to tell the WiNG 5 system where to forward the authentication requests when a guest / visitor user provides their credentials on the captive portal login page. The AAA policy will be assigned to the captive portal enabled Wireless LAN. 1 Using the Web-UI select Configuration Wireless AAA Policy Add: Page 49 WiNG 5.X How-To Guide – Captive Portals 2 Name the policy then click Continue: 3 Set the Server Type to onboard-self then click OK, Exit then Exit again: 4 A AAA policy has now been defined: 5 Commit and Save the changes: Page 50 WiNG 5.X How-To Guide – Captive Portals Running-Configuration Changes: ! aaa-policy INTERNAL-AAA authentication server 1 onboard controller ! 2.3.1.2 Management Policy To allow front desk personnel to create guest / visitor user accounts on the cluster of RFS 6000 Wireless Controllers, a special administrative user account must be defined in the Management policy assigned to the Controllers. This will allow front desk personnel to login to the web-based management interface on RFS 6000 Wireless Controllers to create guest / visitor user IDs, passwords and define time limits as guest / visitors check into the site. 1 Note: Front desk personnel are only provided limited access to the RFS 6000 Wireless Controllers and will not b e ab le to view or change configuration parameters.

Using a profile each RFS 4000 Wireless Controller will be assigned the Captive Portal policy. In addition both RFS 4000 Wireless Controllers will be configured to tunnel the guest / visitor traffic for VLAN 25 over statically defined IP based MINT links which terminate on the RFS 6000 Wireless Controllers management interfaces in the private network. Finally an Auto-Provisioning policy will be assigned and MLCP disabled so that the RFS 4000 Wireless Controllers will not be able to adopt any Independent / Dependent Access Points. 1 Note: If a firewall resides b etween the private and isolated networks, the firewall must b e configured to permit UDP port 24576 (MINT traffic).

Page 89 WiNG 5.X How-To Guide – Captive Portals 2.4 Trustpoints The HTTPS captive portal connection mode requires Public Key Infrastructure (PKI) to provide privacy and mutual authentication. In WiNG 5 certificates are installed into Trustpoints which can be used by the HTTPS service for securing credential exchanges over a captive portal Wireless LAN and device management. By default each WiNG 5 device includes a self-signed certificate which is that installed into a default Trustpoint. As the certificate is self-signed there is no ability for the wireless user’s web-browser or operating system to verify the server certificate used by the HTTPS service. While the default Trustpoint can be used for demonstrations or lab trials, it is recommended that a signed certificate be installed into a new Trustpoint that is assigned to the HTTPS service when the HTTPS captive portal connection mode is enabled. This will greatly enhance the end user experience and reduce support calls. A signed certificate can be issued from a public or private certificate authority. For guest / visitor access applications it is recommended that the certificates be signed by a certificate authority that the guest / visitors web-browsers or operating systems already trusts. For enterprise applications the certificates can be signed by a private enterprise certificate authority which may be already trusted by the managed devices. This section provides a step-by-step example of how to generate an RSA keypair and certificate signing request for WiNG 5 devices which can be signed by public or private certificate authority. The signed certificate and CA root certificate can then be installed into a Trustpoint on the WiNG 5 devices and assigned to the HTTPS service. In this example a common RSA keypair and signed certificate will be installed on two RFS 4000 Wireless Controllers and assigned to the HTTPS service using device overrides. The common name field can be set to an IPv4 address, hostname or wildcard depending on which WiNG 5 device it is being installed on. In this example the common name will use the hostname virtual.tmelabs.local matching the virtual hostname assigned using the captive portal policy. 1 Note: The common name (CN) field in the signed certificate identifies the device to the web -b rowser. The CN field can contain a hostname, IP address or wildcard depending on th e application. For remote Access Point deployments using HTTPS, each remote Access Point will require a static IP address and certificate with the CN field set to each individual Access Points static IP address. Generate a 2048-bit RSA keypair and name it. The RSA keypair will be installed on multiple RFS 4000 Wireless Controllers in a cluster: rfs4000-dmz-1# crypto key generate rsa rfs4000-dmz 2048 RSA Keypair successfully generated 2 View the installed RSA keypairs: rfs4000-dmz-1# show crypto key rsa -------------------------------------------------------------------------------# KEY NAME KEY LENGTH -------------------------------------------------------------------------------1 rfs4000-dmz 2048 2 default_rsa_key 1024 -------------------------------------------------------------------------------- Page 90 WiNG 5.X How-To Guide – Captive Portals 3 Generate a Certificate Signing Request (CSR) using the RSA keypair created above. The CSR in this example uses a wildcard in the common name field so that it can be installed on multiple RFS 4000 Wireless Controllers. The CSR will also be exported to a TFT P server where it can then be signed by a private or public CA: rfs4000-dmz-1# crypto pki export request use-rsa-key rfs4000-dmz subject-name virtual.t melabs.local us tn "Johnson City" "Motorola Solutions" "Field Enablement" email [email protected] tftp://192.168.10.10/rfs4000-dmz.csr Successfully generated and exported certificate request 4 Import the Root CA Certificate issued from the public or private CA that signed the CSR generated above.

Customized login, welcome, fail and agreement pages are typically based on the default pages included with the WiNG 5 system which are downloaded, modified then uploaded back to the WiNG 5 devices or deployed on an external HTTP server. The following highlights the procedure used for customizing captive portal pages when the pages are hosted on a WiNG 5 device. 1. Create a captive portal with the web page source set to Internal. This will generate the required default pages on the WiNG 5 device which can then be downloaded and modified. Ensure the correct connection mode (HTTP or HTTPS) is defined in the captive portal policy as this impacts the HTML code in the pages. 2. Using TFTP or FTP download the login.html, welcome.html, fail.html and agreement.html pages from the WiNG 5 device. The pages will be located in the flash:/hotsport/captive-portal policy-name> folder on the device. 3. Customize each page following the guidelines in this section so that mandatory elements are maintained. 4. If customized pages are hosted on a WiNG 5 device, modify the captive portal policy so that the web page source is set to Advanced. This will ensure that the customized pages are not overwritten with default pages. 5. Upload the customized pages and images onto the WiNG 5 device. 2.5.1 Captive Portal Policy When customized captive portal pages are hosted on a WiNG 5 device the web page source in the captive portal policy must be changed from Internal to Advanced. This ensures that the customized pages will not be overwritten by the default pages if the captive portal policy is modified at a later date. Page 93 WiNG 5.X How-To Guide – Captive Portals If the customized captive portal pages are being hosted on an external HTTP server, a DNS whitelist policy will need to be defined, the web page source changed to Externally Hosted and the URL for each page defined. Externally hosted captive portal pages are covered in section 2.6. 2.5.2 Customizing Pages Each captive portal page includes standard HTML elements which can be customized as well as mandatory elements which must be maintained. The default pages include standard CSS which provides the formatting, layout and colors for the pages as well as various java scripts which are used to pass information to the WiNG 5 device performing the capture and redirection. The login and welcome pages also include a HTML forms which are used to authenticate and logout the users. When the default pages are generated the appropriate java and form scripts are automatically generated in the default HTML pages. This includes if the terms and conditions page is required as well as the TCP port used by the captive portal service. While these variables can be modified it is recommended that the terms and conditions requirement and correct connection mode are defined prior to generating the default pages that are being modified. 2.5.2.1 Login Page The login.html page includes two java scripts and a HTML form which must be maintained in the customized page. The java scripts must be included as -is with no modification; however the HTML form can be reformatted to suit the specific application as long as the action, method and input strings, names and values are maintained: Java Script (between the </head> and <body> tags): <script language=javascript> //Function to get param value from URL. function getQueryVariable(variable) { var query = window.location.search.substring(1); var vars = query.split("?"); for (var i=0;i<vars.length;i++) { var pair = vars[i].split("="); if (pair[0] == variable) { if (pair[0] == "Qv") { return vars[i].substr(3, vars[i].length); } return pair[1]; } } alert('Query Variable ' + variable + ' not found'); } </script> <script type="text/javascript"> function clear() { document.getElementById('f_user').value = ""; Page 94 WiNG 5.X How-To Guide – Captive Portals document.getElementById('f_pass').value = ""; return true;} </script> HTML Form (between the <body> and </body> tags): <table style="width: 100%;" cellpadding="0" cellspacing="0"> <form name="frmLogin" id="frmLogin" action="/cgi -bin/hslogin.cgi" method="POST" onReset="return clear()" onSubmit="return check()"> <tbody> <tr> <td colspan="2" class="form-text">Username:</td> </tr> <tr> <td colspan="2"><input style="width: 250px;" name="f_user" type="text"></td> </tr> <tr> <td> </td> <td> </td> </tr> <tr> <td colspan="2" class="form-text">Password:</td> </tr> <tr> <td colspan="2"><input style="width: 250px;" name="f_pass" type="password"></td> </tr> <tr> <td colspan="2"> <input size="64" name="f_hs_server" id="f_hs_server" type="hidden"> <input name="f_Qv" id="f_Qv" type="hidden"> </td> </tr> <tr> <td colspan="2" class="form-message"><input name="agree" value="yes" type="checkbox">I agree to these <a href="agreement.html" target="_blank">terms and conditions</a></td> </tr> <tr> <td style="text-align: left;"><input name="submit" value="Sign In" type="submit"></td> <td style="text-align: right;"><input name="reset" value="Reset" type="r eset"></td> </tr> <tr> <td> </td> <td> </td> </tr> <tr> <td colspan="2" class="form-message">Please contact the front desk if you have not been issued a username and password.</td> </tr> Page 95 WiNG 5.X How-To Guide – Captive Portals </tbody></form> </table> Java Script (before the </body> tags): <script language=javascript> var hs_server = "NONE"; var port = 444; var postToUrl = "/cgi-bin/hslogin.cgi"; hs_server = getQueryVariable("hs_server"); Qv = getQueryVariable("Qv"); postToUrl = ":" + port + postToUrl; document.getElementById("f_hs_server").value = hs_server document.getElementById("f_Qv").value = Qv document.getElementById("frmLogin").action = "https://" + hs_server + postToUrl; </script> Page 96 WiNG 5.X How-To Guide – Captive Portals 2.5.2.2 Welcome Page The welcome.html page includes various java scripts and a HTML form. Some java scripts can be optionally removed if required as they are used to display the remaining time for the session, however the first and last java scripts must be maintained as-is for the logout URL to function. The HTML form can be reformatted to suit the specific application as long as the action, method and input strings, names and values are maintained. If the remaining time is not required, these elements can be safely removed from the form table: Java Script (between the </head> and <body> tags): <script language=javascript> //Function to get param value from URL. function getQueryVariable(variable) { var query = window.location.search.substring(1); var vars = query.split("?"); for (var i=0;i<vars.length;i++) { var pair = vars[i].split("="); if (pair[0] == variable) { if (pair[0] == "Qv") { return vars[i].substr(3, vars[i].length); } return pair[1]; } } alert('Query Variable ' + variable + ' not found'); } </script> <script language="JavaScript"> //Function to get param value from URL. function getQueryVariable(variable) { var query = window.location.search.substring(1); var vars = query.split("?"); for (var i=0;i<vars.length;i++) { var pair = vars[i].split("="); if (pair[0] == variable) { if (pair[0] == "Qv") { return vars[i].substr(3, vars[i].length); } return pair[1]; } } alert('Query Variable ' + variable + ' not found'); } Page 97 WiNG 5.X How-To Guide – Captive Portals (function() { function listenEvent( o, evtType, fn ) { if(o.addEventListener) { o.addEventListener(evtType, fn, false); return true; } else if(o.attachEvent) { // For MSIE return o.attachEvent("on"+evtType, fn); } else { return false; } } // Gets the timeout from the URL function getTimeout() { var rez = window.location.search.match(/timeout=( \d+)/); if(rez&&rez.length==2) { return parseInt(rez[1],10) } return -1; // No timeout found } listenEvent( window, 'load', function() { var timeout = getTimeout(); var txt='', days, hrs, mins, secs, days_str='', hrs_str='', mins_str='', secs_str=''; if(timeout==0) { txt = "Your allotted time has expired.<br/>Please purchase a new voucher."; } else { if(timeout == -1) { txt = "Your session is valid till the expiry date/time on your voucher."; } else { var seconds_remaining = timeout; // in seconds var interval = setInterval(function() { days_str='', hrs_str='', mins_str='', secs_str=''; seconds_remaining -= 1; if(seconds_remaining<=0) { clearInterval(interval); txt = ''; document.getElementById('txt').innerHTML = txt; alert("Your voucher duration is over.

Individual file uploads are fine when the captive portal pages are hosted on a small number of devices, however this is very inefficient when distributing customized captive portal pages to large numbers of devices such as remote Access Points. To address this limitation WiNG 5.4 includes various enhancements to aid in simplifying the distribution of customized pages to remote Access Points. Both enhancements allow a .tar archive of the customized content to be uploaded to the Controller. The archive is assigned to the captive portal policy so that the Controller knows which pages to deploy for each captive portal enabled Wireless LAN. The archived pages can either be automatically uploaded to the remote Access Points upon adoption or distributed using the CLI or WiNG 5 UI. Note: The .tar file must b e compatible with Linux. When archiving files using Windows it is recommended that WinAce or IZArc b e used as the .tar files from other Windows applications may not b e compatible. Page 103 WiNG 5.X How-To Guide – Captive Portals 2.5.3.1 Web Page Auto Upload The web page auto upload enhancement allows customized pages to be automatically distributed to remote Access Points upon adoption. Upon adoption each Access Point will request the pages from the Controller. If the pages on the Controller are newer than the pages on the Access Point, the Controller will upload the .tar archive to the Access Point over MINT. The Access Points will then un-tar the archive and install the pages into the appropriate directory. 1 Using the Web-UI select Operations <device> Captive Portal Pages CP Page Image File. In the Captive Portal List select the captive portal policy the pages apply to then enter the TFTP or FTP server information where the .tar archive resides and the Path / Filename. Click Load Image. Note for redundant Controller deployments the archive will need to be installed onto both Controllers: 2 Once uploaded a dialog message will be displayed. Click OK: Page 104 WiNG 5.X How-To Guide – Captive Portals 3 Once the .tar archive has been uploaded to the Controller(s), modify the captive portal policy and enable the Web Page Auto Upload option.

Page 105 WiNG 5.X How-To Guide – Captive Portals 2.5.3.2 Captive Portal Page Upload Secondly the customized pages and content can be distributed to remote Access Points using the captive-portal-page-upload command or Captive Portal Pages within the WiNG 5 UI. For this feature the customized pages and content are archived (tar) then distributed to the remote Access Points. The pages can be distributed to individual remote Access Points, Access Points in a specific RF Domain or all Access Points. 1 Using the Web-UI select Operations <device> Captive Portal Pages CP Page Image File. In the Captive Portal List select the captive portal policy the pages apply to then enter the TFTP or FTP server information where the .tar archive resides and the Path / Filename. Click Load Image.

Click OK: 3 Using the Web-UI select Operations <rf-domain-name>. In the Captive Portal List select the captive portal policy the pages apply to. Verify the Upload Via RF-Domain option is selected then click Upload Pages. The status of the upload will be displayed in the Upload History window: Page 107 WiNG 5.X How-To Guide – Captive Portals 2.6 Externally Hosted Pages The captive portal login, welcome, failed and agreement pages can be optionally hosted on an external HTTP server. This is useful for large scale deployments when complex customized pages need to be deployed or the web-browsers session needs to be redirected to an external secure guest access provisioning server. To enable externally hosted pages the web page source in the captive portal policy is set to Externally Hosted and the URLs are defined for each page type. The URL can include the IPv4 address or FQDN of the server hosting each page as well as the path and page name. When secure guest access is deployed only the login URL needs to be specified as the web-browsers session will be captured and redirected to the XpressConnect server where the device can be provisioned for secure access. By default a captive portal will only permit limited access to the network for unauthenticated devices. To permit access to the externally hosted pages a DNS whitelist policy must be defined and assigned to the captive portal policy. The DNS whitelist can include the IPv4 addresses and/or hostnames of the external hosts you wish to permit access to. This provides a walled garden for unauthenticated devices as it permits access to only the hosts you specify until the user has been permitted access to the captive portal network. For secure guest access applications or BYOD the access type in captive portal policy can be configured in a number of different ways depending on the specific deployment model required. For example the RADIUS access type can be enabled with no AAA policy assigned to lock the users into the captive portal network. The users will only be permitted access to the XpressConnect server and cannot break out of the walled garden. Once their device has been provisioned by the XpressConnect server, their device will automatically associate and authenticate to a secured Wireless LAN. A different approach would be to permit secured and non-secured guest access. The access type can be set to no authentication with a terms and conditions page assigned. With some minor customization to the login page the guest / visitor users can either elect to provision their devices using the XpressConnect server or accept the terms and conditions page and be permitted access to the non-secured Wireless LAN. The guest / visitor users can also be authenticated via RADIUS if desired. Page 108 WiNG 5.X How-To Guide – Captive Portals 2.6.1 DNS Whitelist Policy A DNS whitelist policy will be defined that permits access to a HTTP server deployed in the isolated network or DMZ that is hosting customized login, fail and agreement pages. The servers IPv4 address 192.168.25.5 will be added to the DNS whitelist which will be assigned to the captive portal policy. 1 Using the Web-UI select Configuration Services Captive Portals DNS Whitelist Add: Page 109 WiNG 5.X How-To Guide – Captive Portals 2 Enter a Name then click Add Row. Enter the IP Address, Hostname or FQDN of the HTTP server then click OK and Exit. In this example customized pages are hosted on a HTTP server in the isolated network with the IPv4 address 192.168.25.5: 3 Commit and Save the changes: Running-Configuration Changes: ! dns-whitelist TMELABS-GUEST permit 192.168.25.5 ! Page 110 WiNG 5.X How-To Guide – Captive Portals 2.6.2 Captive Portal Policy An existing captive portal policy will be modified to redirect captive portal users to the externally hosted pages hosted on the HTTP server (192.168.25.5) deployed in the isolated network or DMZ. The DNS whitelist policy will be assigned to permit guest / visitor access to the HTTP server which hosts the login, fail and agreement pages. The web page source will be changed to externally hosted and the URL for each page defined. The welcome page will URL will be defined to redirect users to the company websi te. 1 Using the Web-UI select Configuration Services Captive Portals Edit: Page 111 WiNG 5.X How-To Guide – Captive Portals 2 Assign the DNS Whitelist policy then click OK: 3 Select the Web Page tab then set the Web Page Source to Externally Hosted.

Verification 3.1 Web Based Guest User Provisioning The following outlines the procedure for creating a guest / visitor account on an RFS X000 Wireless Controller using the web-based management interface. The front desk personal will use the special Web User role account defined in the Controllers management policy to login to the management interface. This will present a special UI which will permit the creation and printing of guest / visitor accounts. When a guest / visitor account is created on the system it will be mapped to a user pool and group so that the user can be authenticated using the integrated RADIUS server. The accounts will be automatically purged 24 hours upon expiration. 1 2 Using a web-browser connect to the management interface on the RFS 000 Wireless Controller that is authenticating the guest / visitor users. Login using an account which has the Web User role assigned: From the list select the user pool for which the guest / visitor account is to be created on then click Create New User. In this example the user pool TMELABS-GUEST has been selected: Page 114 WiNG 5.X How-To Guide – Captive Portals 3 Define a Username, Password and optionally enter an Email address and Telephone number. Select a User Group then define the Start Date/Time and End Date/Time the account is valid for. Click Create User.

Page 115 WiNG 5.X How-To Guide – Captive Portals 3.2 Capture and Redirection The following provides an overview of the re-direct URLs as well as the different types of pages presented to captive portal users. The pages in this example are based on the default login, welcome, failed and agreement pages generated by the WiNG 5 system which have been customized using the captive portal policy: 1 When a user that is connected to a captive portal enabled Wireless LAN opens their web browser and attempts to access a web-site, their web-browser session will be captured and re-directed to a login or terms and conditions page. Depending on the captive portal policy configuration, the connection will either be HTTP (port 444) or HTTPS (port 880) and will include either the IP address or virtual-hostname of the WiNG 5 device that has performed the capture and redirection. The URL will also include the captive portal policy name, the name of the page being displayed as well as various strings of information used by WiNG: 2 If authentication is enabled, a login page will be displayed. The login page will require the Wireless LAN user to enter valid credentials before being permitted access to the Wireless LAN. The login page can optionally include terms and conditions which the user must agree before being permitted access to the Wireless LAN. The user can be authenticated locally on an RFS X000 Wireless Controller or against an external RADIUS server: Page 116 WiNG 5.X How-To Guide – Captive Portals 3 If the authentication succeeds, the web-browser will be redirected to a welcome page. The welcome page typically displays a message as well as presents information such as the remaining time for the session: 4 If the authentication fails, the web-browser is redirected to a failed page. The failed page typically includes a message as well as a URL so that the user can attempt the login again: Page 117 WiNG 5.X How-To Guide – Captive Portals 5 If no authentication with a terms and conditions page is enabled, the web -browser is redirected to an agreement page. The agreement page typically includes the terms and conditions the user must agree to before being permitted access to the Wireless LAN. Page 118 WiNG 5.X How-To Guide – Captive Portals 4.
