This happened to me recently and I stumbled across a neat feature of OpenSSH (the ssh client on everyone’s computer). The wonders of ssh never cease to amaze me!

You can use the “-D” flag of openssh to create a SOCKS proxy.

The command first:

$ ssh -D 9999 username@ip-address-of-ssh-server

This of course connects you to the server specified by “ip-address-of-ssh-server”. Needless to say, you (username) must have an ssh account on the server. In addition, this will create a SOCKS proxy on port “9999″ of your computer. This is a tunnel to the server. Now all you have to do is set the preference in Firefox to use a SOCKS proxy. The proxy is, of course, “localhost”, with the port 9999.

Now when you browse, all the connections you make to websites will seem to originate from the server to which you SSH-ed. In addition, all outgoing and incoming data for the browsing session will be encrypted since it passes through the SSH connection.
