I have 2 Exchange servers on two different LANs in two different states. I'd like to be able to connect the two Exchange servers to share resources between them. Each LAN has a static IP, so I was thinking VPN. One LAN uses a NT 4 Workstation with a proxy server on the static IP (the Exchange Server is behind the proxy server), the other LAN has the PDC (and Exchange server) directly on the the other static IP.
Can anyone give provide some advice as to how to create a VPN between the two (using MS platforms)? I tried running an OpenBSD box on both ends, but I had tons of problems with the VPN and using the box as a router for each LAN.
