Vodafone 3G connect to VPN but can connect to any servers?

whiteford · ‎01-15-2008

Hi, I have a Cisco Concentrator that has site-to-site VPN's and Client VPN's all working. Users can connect from home using their Cisco VPN client either by DSL or wireless in a cafe.

The problem I have now is we are trying to get a Vodafone 3G card to connect. It does connect to the concentrator as I get the logon box and it authenticates my username (RADIUS). However I can't ping any servers from the laptop once connected.

Does I need to do anything special with the Concentrator?

Uninstall the vpn client and the wireless application. Install the vpn client and test the connect and verify works. Then install the wireless application. In the TCP/IP config of the card select "Disable NetBIOS over TCP/IP" and reboot the system. Make sure Client for MS networks and File and Print sharing are enabled. Make sure transparent tunneling is not unnecessarily checked.

As last resort you can try using IPSec over UDP instead of IPSec over TCP.
