SSH port forwarding

To forward a connection from a local port over an ssh connection to a port on a remote system use: ssh user@host -L source_port:dest_host:dest_port

• host - The host that user is logging into via ssh.
• source_port - The port on the local system to forward over the ssh connection.
• dest_host - The remote system that connections made to the local port will be forwarded to from the other end of the ssh connection.
• dest_port - The port of the remote system that connections will be forwarded to.

Only root can forward privileged ports.
