VPN works under Vista but NOT with Access Connections

[jamess]

I have a strange problem. When I enable the VPN using windows scheme etc. it works perfectly, I can access all my shared company data etc. But when I do the "magic" enable VPN and enable all that's needed in Access Connection Advanced options, when I switch to my home network, the VPN connection gets established, but I can not access the "outside" world.

In short:
Vista Connect to: everything OK, VPN working and internet access working

AC by ThinkVantage: VPN ok, no access to the internet WWW

Why? Can somebody help me? I would really like to have the "automatic" functionallity of the Access connections.

Thanks
