VNC and VPN working together problem

Here is the situation. I connect via VNC to a computer running UltraVNC server. Then, I connect to a VPN on the UltraVNC server computer that I 've just connected to. Once the VPN connection is established, the VNC connection to the UltraVNC server is lost, thus ending my VNC session. How can I connect to a VPN from the UltraVNC server computer and not kill the VNC session? All computer are running Windows 7.

I think you need to untick the Use default gateway on remote network option on the VPN connection.

1. Edit the VPN connection properties.
2. Click on the Networking tab.
3. Click on Internet Protocol Version 4.
   1. You may also need to disable Internet Protocol Version 6
4. Click the Advanced button.
5. Untick the Use default gateway on remote network option.
6. Press OK to apply the new settings.
