This is how to open a SSH connexion to a serveur hidden behind a NAT gateway.

We use a reverse SSH tunnel:

nated-host$ ssh -R 2222:localhost:22 anyuser@public-host

This command opens 2222 port on public-host, forwarding it to local 22 port on nated-host.

Finally, from public-host we connect to 2222 local port with SSH, to end on nated-host:

public-host$ ssh -p2222 localhost
