It is not a filter issue, it is a routing issue.

Look at the properties for the vpn connections. Under tcp/ip settings there is a check box for using the default gateway on the server. If that box is on, you will lose the ability to use the internet while the vpn is up.

To fix this, uncheck the box. This will allow you access to the internet while the vpn is up, but may lose the route to the LAN on the other side, depending on how your system does routing.

To force a correct route to your LAN over the vpn:

Create a batch file on your machine with a route command in it which specifies the server on the other side of the vpn as the router for the LAN address at the other end.

Example:
Address at the far side of the vpn 192.168.42.1
Network at the far side of the vpn 192.168.3.0

The route command is:
ROUTE ADD 192.168.3.0 MASK 255.255.255.0 192.168.42.1 METRIC 1

Set up a desktop icon to run the batch file.
Double-click the icon after you connect the vpn.

Good luck.
