I have a Linksys WAG300N, I'm accessing my LAN with Wifi and everything works fine on my Windows 7 Enterprise laptop. When I try to connect to my company's VPN the connection succeeds, but I cannot access any internet site either within my work network or public site like Yahoo or Google.

In my Linksys control panel I already verified all types of VPNs are enable to passthrough. Normal IPSec and Windows VPN worked in the past without any problems.

CheckPoint seems to have a solution, but I do not have the ability to change the IP in my client and of course using another NAT device in between is not a solution for me.
