Re: Having problems using a wlan bridge with cisco wlc
The issue your experiencing is exactly what you think it might be. By default the WLC's don't like to see multple IP's coming from a single mac address if the client is detected as just a client. If it detects it as a WGB (Workgroup Bridge) Client then there are no issues. One possible solution is to enable 802.3 Briding mode on the WLC which should resolve your issue. You will find this setting under Controller> General on the WLC GUI. If this doesn't resolve the only other option I am aware of is to use a CIsco IOS AP in Workgroup Bridge mode in place of your linksys bridge.
I had a similar issue with some older linksys bridges that used to be connected to an autonomous system.
