In order to provide more control over the port forwarding feature, it would be nice to add these options to the per-key configuration on the server side: no-X11-forwarding no-agent-forwarding no-pty command="sleep 10" client-local-forward 25 client-remote-forward 26 This would allow a remote client to establish port forwarding, but only sending to the server port 25 (SMTP) and only listening on server port 26. The client could connect server port 26 to his own mail server. The purpose is that you can have multiple people with authority to port-forward, but each must use a specifically assigned server port (here 26). Noone could `steal' another person's assigned port.
