Having a issue getting DHCP working with clients. We have 1131 access points. They have assocaiated with the controller. Clients can connect but are not getting an IP address from the DHCP server. Not using internal DHCP in the WLC.
At our school the main networking group from a VPN for authenication. We place the AP and controller on the back side of the VPN. Security is open on the AP as the VPN handles that. We are given the IP address of the 2 DHCP servers. The DHCP server exist outside the VPN. The WLC and APs exists on the same private subnet. The DHCP servers exist on another subnet outside the VPN.
I have tested using the WLC DHCP and it works as long as the DHCP addresses are in the same subnet as the WLC and APs.
To have the WLC and 1131 APs work on this wireless nework we need to get the WLC to work with the external DHCP servers. I didn't know id this is a routing issue or if the DHCP servers do not support DHCP relay.
