Overview of Traffic Redirection
The redirect server is part of a captive portal system that redirects subscribers' Web requests to a captive portal page. You can use a captive portal page as the initial page a subscriber sees after logging in to a subscriber session and as a page used to receive and manage HTTP requests to unauthorized Web resources.
If you run the SRC software on Solaris platforms, a captive portal uses an instance of the redirect server installed on a host in the same network as a JUNOSe router. Your network configuration must not have any routers between the JUNOSe router and the redirect server. An intermediate router would look at the destination address that is still present in the packets and would route the packets there rather than to the SAE. One way to overcome this limitation is to set up a tunnel between the JUNOSe router and the redirect server.
