Scenario: Using VPN Client 3.5.1 (B) behind a 2600 router doing NAT and IOS ver 12.2.(8)T4. Destination is a VPN 3000 concentrator. Client can authenticate and connect, but can't reach anything. Tried both no tunneling and udp tunneling... tcp tunneling isn't enabled on the 3000.
Any ideas why this won't work? Debugs reveal some packets from 3000 are being dropped, but not enough info to determine why...
