I'd like to initiate an x2go session from a server behind a firewall to a listening client with port 22 open. How can that be done? thanks!
To my knowledge this is not possible with x2go. But I am pretty sure is possible by using the bare nx libs (nxagent/nxproxy. But you have to setup everything by hand then.

Maybe do some kind of SSH tunnel first?

There's no way to do that automatically. You could ssh in to the client and start x2goclient there, and, given a session profile that is configured for autologon, you could pass that session profile, but it would require that the user account you're sshing in with has permissions to access the local X display, and you'd need to set the DISPLAY variable accordingly.
Also, for this trick to work, you'd have to set up an SSH tunnel pointing back at your server.
Pretty hairy, if you ask me.
What's the point of doing this?

Run "ssh -R 12345:localhost:22 user@client" on the server (see man
page of ssh client for correct usage of -R option) and open up a
reverse tunnel from some port (e.g. 12345) on the client to port 22 on
the server (to be more precise, localhost:22).
Then configure X2Go Client on the client to connect to "Host:
localhost" and "Port: 12345" and you have your X2Go session ready to
roll.

That's not what he asked for. He wants a listening client, like vncclient in "-listen" mode, and wants the server to initiate the connection, without any manual interaction on the client side. The only way to approximate that behavior is starting x2goclient over the server-initiated ssh connection, and passing the required parameters for an autostarted session - see my more detailed reply to him.
