The problem started after I upgraded my 2811 router to IOS 15 (from 12.4xxx).
I had to reinstall VPN AnyConnect.
Router IP: 192.168.123.1
Connecting to VPN gives me 192.168.123.200
Now I can ping 192.168.123.1, but no more any other IP at the same subnet at all.
I have done a diff of the old config and the new one and can't find any difference on the webvpn parts and access-lists/NAT.
