How to Setup a VPN using DD-WRT Router

Definition

A VPN (Virtual Private Network) is a virtual encrypted tunnel through an network (e.g. the internet) to connect a client (or whole network) to a server (or network). This allows you to not only use local network resources, such as printers or file servers, from anywhere you have an internet connection but also gives you a safe tunnel to browse the web through. Using a VPN you can browse web sites from a free access point at a hotel without worrying about others seeing your data. This is also a common way to bypass web content filters. -DD-WRT Wiki
