A vpn is "Virtual private network". A great tool for secure communication between networks through the internet. It has always been expensive and hard to configure for most people. But there is a great program that can do this with p2p technology. Hamachi creates a secure tunnel so two or more networks can connect.

Hamachi is easily configured and uses the same technology as Skype. This makes it extremely easy for clients to connect to each other, despite firewalls and routers and so on.

Home users can with ease use Hamachi to connect two or more separate LAN networks.
