I had a PC set up with a VPN. I used the Windows 7 firewall to block all NON-VPN traffic to the internet, but all LAN traffic was allowed. So, with the VPN connected I could connect to all networked machines and the internet. Without the VPN connected I could only connect to the LAN and had no internet access.

Unfortunately my drive failed, and I'm setting up the machine again with a replacement drive. I can't for the life of me work out how to set up the firewall again.

I can easily set it up to block all NON-VPN traffic, but can't work out how to that and still allow all LAN traffic whether the VPN is connected or not.

Some pointers would be useful.

Thanks.
