Maybe someone can help me out?
I just finished setting up a trial "Cisco Virtual Wireless Controller" with nearly the same configuration as our Physical "Cisco Wireless Controller" with the exception of having 2 ports. Anyhow, I managed to get everything working except for the WEB AUTH on the Guest WLAN. When a client connects, he gets a DHCP address from our ASA but when we try to get to a website, we never reach the WEB AUTH page.
What I tried so far is..
add a DNS Host Name to the virtual interface and assign it to our internal DNS server.
dns name was resolving but we were unable to ping 126.96.36.199
changed the virtual ip from 188.8.131.52 to 184.108.40.206 and modified the DNS entry
dns name resoved but still could not ping 220.127.116.11(I think this is normal)
changed the virtual IP to a private address of 192.168.102.1 and modified the dns entry
I've attached some screenshots of our configuration.
