A Virtual Private Network (VPN) allows you to securely link two or more machines together over the Internet. Such a network setup comes in useful when it is not feasible to have a direct network connection. A VPN is widely used when requiring to link offices which are a great distance apart and for individuals to connect to the network from a remote location. This allows clients to use the facilities of the local network even when not physically in the same location.
