When I connect to an XP VPN the default gateway for the connection is the IP address of the VPN server machine.
I think this is the reason I cannot connect to the internet via the VPN.
How do I change the default gateway of the VPN connection to the IP address of the remote router?
Disable the option
Use default gateway on remote network.
You can find this bygoing to network connections and clicking the Advanced button in the properties page of Internet Protocol Version 4 (or 6) of your VPN connection.Why do I lose internet when making a VPN connection?
