WLC module in 2811 not forwarding wlan traffic

i have a WLC module inside a 2811 router. everything is working (ap connecting, administration) except traffic from WLAN is not leaving the wlc to the router.

The wlc is sending the dhcp packages to the default gateway (asa5510). See file wlc_dhcp.txt. The 2811 router isnt receiving the packace (at least a debug ip package didnt show it). Router interface config:

interface wlan-controller1/0

ip address


interface wlan-controller1/0.18

encapsulation dot1Q 318

no snmp trap link-status

bridge-group 18

bridge-group 18 spanning-disabled

interface Vlan318

no ip address

bridge-group 18

bridge-group 18 spanning-disabled

Whats wrong, why are the packages from vlan318 not reaching the router? Why are they not forwarded?

thanks, Martin

Why don't you use 2811 router as your gateway instead of the ASA5510?? I think it will be easier, cause your problem could not be of wireless, it seems that's a problem with your ASA to access your inside network.

Hope this helps,

Because the ASA is handling the WLAN Traffic (Firewall, VPN) and not the 2821. Also 6 WLC440x at our main locations are setup the same and they are working .
