We have a WLC4404 and and anchor controller WLC4402 to provide guest access to the wifi net. We configured both in the same mobility group, and the guest ssid to attach to the mobility anchor 4402. All is working fine until we enable the web policy authentication on the 4402. In this case the client join the guest ssid but neither get an ip address from the dhcp server nor go anywhere. Is we disable the web authentication all works fine again. We are runnig 22.214.171.124 on both WLC. Anyone can help us?
Two things you might check. (1) The 4404's mobility anchor should point to the 4402, and the 4402 should anchor to itself. (2) Make sure you are configuring the same security policy for the SSID on both the 4402 and 4404. So if the SSID is "guest" and you turn on web authentication on the 4402, make sure "guest" is on the 4404 with web authentication. We are using a similar setup for guest access at several sites.
