  1. Local Port Forwarding

    Forwards a connection from the client host to the SSH server host and then to the destination host port.

  2. Remote Port Forwarding

    Forwards a port from the server host to the client host and then to the destination host port.

  3. Dynamic Port Forwarding

    Creates a SOCKS proxy server that allows communication across a range of ports.

  • Client: Any machine where you can ssh to enable Port Forwarding
  • SSH Server: A machine that can be SSHed into by Client
  • Target Server: A machine to which you want to establish a connection, usually to open services on this machine to the outside world.

Notice: both Client and SSH Server can be Target Server, it doesn’t really need three machines to perform Port Forwarding! However, Dynamic Port Forwarding will not be only one Target Server, but it can be dynamically determined.
