Here's our topology:1130 series APs -> 4400 series WLC (mgmt vlan 51, client dynamic interface vlan 360) -> Catalyst 4500 series -> DHCP server (vlan id 11)We appear to be unable to relay DHCP requests from a wireless client on VLAN 360 to the DHCP s...

Well the option to have "disable dhcp proxy" as a configurable option on the WLC makes it just all the more confusing :)And just to report on what we're seeing: the virtual interface for the wireless VLAN is proxying the DHCP (say 10.5.18.2 on vlan i...
