WISPr-Redirection-URL with Cisco 3550 switch

[Morris, Andi]

Thanks for the swift and informative response.  I think there's an option to do with ACLs inside the Cisco routing features.  I hadn't intended on using ACLs, but it may be that I have to.

Cheers,
Andi

  No.  RADIUS does authentication, not routing, and not HTTP.   You need
a captive portal.

  It's specific to wireless ISPs who implement a captive portal.

  I don't think so.

  See the Cisco documentation for how to configure filtering/firewalling on Cisco NASes.

  In RADIUS, the server just sends *hints* to the NAS.  The NAS is really in charge of all filtering, firewalling, etc.
