The RemotePort Property syntax has these parts:

The RemotePort property defines where all accepted connections will be forwarded, in association with the RemoteAddress property. You should always set this property. If you create a LocalListen tunnel, RemotePort defines where the SSH server will connect at the other end. If you create a RemoteListen tunnel, RemotePort defines where the SSH server will listen for connections that will subsequently be forwarded to the local computer.
