 SSH remote port forwarding is built right into ssh itself, and is quite simple:

 Here is an example of this in practice, forwarding port 80 and 443, by forwarding ports 8080 and 8443:
 
-	/usr/bin/ssh -nT -R 8443:localhost:443 -R 8080:localhost:80 -i $IDENTITY_FILE -p $SSH_PORT $DEST "(sudo socat TCP-LISTEN:80,fork TCP:localhost:8080) & sudo socat TCP-LISTEN:443,fork TCP:localhost:8443"

 However this command assumes that the remote user has access to sudo with **NO PASSWORD**. Alternatively you could create a similar service (this time as a system service) on the remote server running the socat commands.
