I have a 4402 WLC configured with a guest wlan using the internal DHCP on the controller and web authentication. The client is finally getting an IP, the web authentication page and can login, but cannot get to the internet. The wlc connects to a 3750E switch, and we have an ASA 5510 appliance. I have configured a vlan for the guest clients, but still cannot see the ASA. It looks like the wlc cannot send to the ASA, but, the internal wireless users are working fine.
