Hamachi is a program that allows you to form connections over the internet that usually could only be done physically-basically making it computer networking software. It's free and is available for compatibility with Microsoft Windows (Vista included), Linux, and Mac OS X.
Once Hamachi is downloaded and installed the rest of the process is relatively simple and anyone can set up a private server. Once Hamachi is opened up, there are three icons that show up along the bottom of the rectangular menu. Clicking on the triangular icon opens up the networking menu, where you can join a network if you have the proper information or set one up. Setting one up is as simple as choosing a name and creating a password.
