Everything depends on the routes. If the same network he is going out on happens to be matched by a route assigned to the vpn connection, you'll definitely have problems. That was my point. Routing is the first thing I'd check into. > > I would be interested... In windows when you use the Cisco VPN client > (assuming you do) does it use Ipsec/UDP or Ipsec/TCP ?

The Cisco client defaults to udp (udp encapsulation of ipsec). The vpnc program defaults to using a special protocol (something to do with ipsec) called "ESP." If you pass vpnc the --udp flag, it defaults to udp packets. (I think). I'd definitely try the --udp flag to force vpnc to use the udp encapsulation.
