We are deploying 4402 controller ( ver 4.2), and trying to define a WLAN for guest access with web auth.
Our VLAN address in the controller is 192.168.20.2 and default gateway is 192.168.20.1 ( which is defined in the core L3 switch.
When clients connect to thic WLAN, follwing happens.
If the default gatway given from the DHCP is set to 192.168.20.2, wnd client try to access internet by entering any URL, the auth page displays . But after authentication the traffic cannot go out form the VLAN becase the defauld gateway is 192.168.20.2
But when we set the default gateway to 192.168.20.1 the AUTH page does NOT displays. We have to enter "https://18.104.22.168/login.htm" to get this page. After authentication, traffic can flow in and out VLAN without any problem.
Is there any additional config to be done at the WLC to diaplay the web auth page for any URL ?
