 I'm not sure if Net::SSH supports this, but basically what you want is
 this:

    $ ssh -f -L 1234:remote_host:22 proxy_host < /dev/null &> /dev/null &

    $ ssh -p 1234 localhost

 where "1234" is a number you pick.  It will be the port on the client
 machine that you can use to initiate a SSH connection to the remote
 machine (remote_host).  Note that "remote_host" will be resolved by
 "proxy_host", not by the client.

 I'd suggest you try it first on the command line and once you get it
 working wrap it with Ruby.

 HTH,
