In this video I go through the process of setting up an SSH tunnel to hide an IP and also setting one up to create a simple router, in this case, on a dual-homed host. The second instance could also be used to route traffic through an encrypted channel on an unexpected port. For example, it could be used to route IRC traffic through port 80 to avoid a network policy. In addition to the demonstration of setup, I analyze traffic from the points of view of the browsing computer, the host for the tunneling, and the recipient of the tunneled traffic.
