Unified Services Router User Manual 2.5 Captive Portal  DSR-250/250N does not have support for the Captive Portal feature. LAN users can gain internet access via web portal authentication with the DSR. Also referred to as Run-Time Authentication, a Captive Portal is ideal for a web café scenario where users initiate HTTP connection requests for web access but are not interested in accessing any LAN services. Firewall policies underneath will define which users require authentication for HTTP access, and when a matching user request is made the DSR will intercept the request and prompt for a username / password. The login credentials are compared against the RunTimeAuth users in user database prior to granting HTTP access.  Captive Portal is available for LAN users only and not for DMZ hosts. Advanced > Captive Portal >Captive Portal Sessions The Active Runtime internet sessions through the router's firewall are listed in the below table. These users are present in the local or external user database and have had their login credentials approved for internet access. A ‗Disconnect' button allows the DSR admin to selectively drop an authenticated user. Figure 10: Active Runtime sessions 27
