SSH tunnel

ssh -N -R 5555:1.2.3.4:666 user@hostname
  • 5555 is a port you make up
  • 666 is the port to which you are forwarding
  • 1.2.3.4 is the IP of the target host to which you are fowarding
  • hostname is the host where port 5555 will be made available
  • you run this command on a third machine (e.g. your local host)

This results in  hostname:5555  getting forwarded to  1.2.3.4:666
