This post seems to follow on from my previous post regarding a quick and easy proxy server on Ubuntu! And sticks with the proxy theme quite nicely.
I’ve come across a couple of corporate VPN solutions that appear to open a SSH tunnel for the VPN and push all traffic down it accordingly. Sometimes it’s very useful to be able to test routing from a remote source, or to give your users a cheap and quick VPN. (As well as in this case the VPN and Firewall provider didn’t provide a native Mac VPN client.)
