Hi, I am setting up a new wireless network using WLC 4402 running in Layer 3 mode, LAP 1242AG and a NAC Appliance running In-band/real ip gateway. My problem is that I cannot get the NAC Appliance to assign a DHCP address to the Wireless clients.
I can get a dhcp address from the controller ok. And If I connect via a wired port I can get a dhcp address from the NAC Server.
I have sniffed the untrust interface of the NAC and when I try to get a DHCP IP using wireless, I can see the DHCP Discover going in and DHCPOFFER coming back out, however it is like the WLC is not passing the offer back to the wireless client. I have configured DHCP Override on the WLC to point to the untrust interface of the NAC but it still does not work. I have a VIP of 22.214.171.124 configured on the WLC.
The WLC is running code 126.96.36.199. If I give the wireless client a static ip address I have no problem connecting out via the NAC.
