Set up a SSH-based point to point connection

OpenSSH version 4.3 introduced a new feature: the ability to create on-the-fly “Virtual Private Networks” via the tunnel driver (the so-called “tun” driver). This allows you to create a network interface that bridges two physically disparate network segments in different locations. This article explains how to use SSH to set up SSH-based point to point connections with OpenSuse 11.0 which can then be used to create routes that create virtual private networks.
