The following is a list of steps and screenshots to set up a VPN connection to a site-to-site VPN on Apple Mac OS X. This happens to be a Windows 2003 Server running a VPN for this example but this tutorial should work for other VPN's as well. Mac OS X has a built-in VPN client so there is no need for 3rd party software to make the connection to a VPN:

Open System Preferences from the Apple menu.

The following are the steps you would need to take if you want to configure a VPN on a Windows 2003 server where you only have a single network card (NIC) exposed to the Internet. What we will do here is configure a site-to-site VPN so that clients can connect securely while still allowing other types of web traffic such as HTTP (port 80) and/or RDP (port 3389) to connect. This method sets up a secure tunnel for clients while allowing other types of web-based services to still be open and exposed on the same network card.
