I have a Lenovo Laptop running Windows7 x64. Using the 3g sim within the laptop I can connect to the internet, browse internet sites, and connect to my Cisco VPN router. But I cannot connect to any resources within the domain, or ping anything behind the router. I can from every other device connecting to that vpn router so I know that the router is configured correctly. If I connect to a local wireless source and then connect to the vpn I have complete access.
