If you are running your GPS tracking system using RavTrack PC on a Windows XP computer, you may want remote users to be able to access the tracked objects database from a remote computer that is not on your local netwrok. You may be able to do this using a Virtual Private Network (VPN) connection.
This article describes how to setup VPN access to a Windows XP computer. VPN access will allows you to network two computers together, even if they are not on the same local network. It will work across the Internet, while still maintaining security and privacy.
You will need Windows XP Professional with SP2 or SP3 installed.
