Wireless: no dhcp over a bridge

baracus

I want to setup a wireless bridge going from a current network (siteA), to a new small network across the street (siteB). I have 2 Cisco 1131AG Access points. I have no need for any client access, only the bridge. I have the interfaces up and can ping across, however, no dhcp requests seem to come over the bridge. Where am I going wrong??

DHCP messages are broadcasted via UDP and will not route across a layer 3 interface. Have you tried the ip helper-address on the interface? try putting the helper-address command with the dchp server's IP address on the client side L3 interface.

ip helper-address is the shizzle.
