SSH Tunnel Example

Tunnel ssh from Local Machine to Remote Machine
and from Remote Machine to a Local Machine on
Remote Machines network.

Local to remote machine with 5900 tunnel
ssh -L 5900:127.0.0.1:5900 -l username -p 22 theactualurl.net

Remote to machine on remote network with 5900 to 443 tunnel
sudo ssh -L 5900:127.0.0.1:443 -l username -p 22 remotemachine.local

This allowed one on the local machine to connect to a webserver using https on the remote machines network. The address on the local machine is https://localhost:5900 or https://127.0.0.1:5900 and the connection is tunnelled through port 5900 but the actual server uses port 443.
