I recently got an Aironet 1240AGs that is connecting to a catalyst 3560 switche (layer 3 switche). I have DHCP on a Windows 2003 server. The native vlan on the Aironet gets a DHCP address from the Windows 2003 server and assigns it to the wireless clients. However, clients on different SSID's on different VLANs do not pick up a DHCP address. The same VLANs on the switches work fine with the helper address configured. I tried assigning helper address on the fast ethernet sub interface for each VLAN on the aironet but it did not help. Can anyone point me in the right direction?
I have this problem too.
