we have a problem concerning secure guest access. One controller 4402 is installed in DMZ and is working as guest anchor WLC. The guest user terminates as this anchor wlc. From this controller the client will get the ip address but when the user will open the browser and insert the url like www.cisco.com, there is no redirect to the web authentication page. If we try to reach the virtual IP via Web browser the authentication page will not be seen. Proxy setting in browser are deactivated. DNS works, if no authentication is configured Internet access is working well. But if we configure "Pass Thru", the client is in status "Authentication required" again.
Has anybody any ideas?
Thanks a lot, Martin
