openwrt routing issue

I think this is a configuration issue in openwrt, but I'm far from an 
expert. I figured I would try here just in hase I am wrong or someone 
here sees something obvious.
I'm using openwrt backfire 10.03 on a Buffalo WZR-G300NH and the 
openconnect 2.25 with a patch david provided a few months ago.
I am able to connect to the Cisco VPN server and pass traffic from the 
router itself. I can't pass any traffic from a PC connected to the 
Buffalo by wifi. Since I can from the router, I'm assuming this is a 
configuration issue on the router itself. See ifconfig and route info 
below. The VPN IP I receive is 10.70.6.105. I am trying to ping 
10.92.X.X IPs on a remote network. The routing info on the router itself 
looks correct. Anyone see anything obvious I am missing? I don't see any 
openconnect activity when running it with the verbose option. I swear I 
had this working while testing a few months ago. I had to put it aside 
to work on some urgent projects, and now something seems to have died....
