We just recently did this. We ran into the same problem, and it came down to address spoofing. I don't remember all the specifics, but when using office mode, the client uses the office mode IP address for all packets. The WLAN interfaces topology is probably set to some other address scheme that does not include this, and therefore it is going to drop it. Unfortunately, if you setup the topology to include the office mode subnet, the external interface may begin to drop traffic because they expect traffic originating from that subnet. I think all we have done to this point is disable anti-spoofing on the WLAN interface. This does pose potential problems, so be careful.
We have not had the time to really sit down and figure out how to implement this with anti-spoofing enabled on that interface, so if anyone has any suggestions, it would be appreciated.

Greetings, all. It's my first post to this list, so please bear with me. We are implementing a WLAN here. The WLAN is sitting on it's own interface on our R55 SecurePlatform box. Due to the 3-5 minute lag of being able to ping via WINS name (whether on the WLAN or from home) I decided to use Office Mode. Most of the WLAN users will also be VPNing in from home via SecureClient. When I connect up with SecureClient R55 it tells me Tunnel Test failed (-121). When I connect up with SecureClient R56 it tells me that it connected successfully, but it exhibits the identical symptoms to R55. The symptom is that I am unable to hit anything on the trusted side of our firewall. I researched the Tunnel Test Failed message and followed the step in sk10980 but I still got the Tunnel Test failed. I also set the Office Mode to "Support connectivity enhancement for gateways with multiple external interfaces" without any luck. Has anyone gotten Office Mode to work from a separate interface of the firewall (not external)? I would be happy to provide any additional information or logs. Thanks!
