I think the x2go proxy can do that. Mike Gabriel and others could give you a definite answer.

Stefan Baur's instructions for using SSH forwarding via the command line will work. Just note that in the SSH server settings, you will need to enable TCP forwarding if it is not enabled by default. The settings are usually in /etc/ssh/sshd_config .

I think that you can also use x2go client's built in feature to use a "proxy server". I think this feature is just SSH forwarding. Ultimately, which way of doing SSH forwarding is your preference. To use the x2go client's built in feature:
1. In x2go client, define a session for each x2go server host your ultimately want to connect to. The host should be the hostname or the IP address of the x2go server host
2. Under the preferences for each session, enable "Use Proxy server for SSH connection".  Then enter the vpn client box's hostname or IP address as the "host" of the proxy server. The "type" of proxy server should set to "SSH".

And of course, you can use x2go to connect to this headless box. I recommend you install the full desktop environment you intend to use, but disable X from starting automatically. How to do this varies from distro to distro. For example, on Red Hat and Fedora, you would make the default runlevel 3 instead of 5. On Ubuntu, you would disable the service / upstart job "lighdm" (or "gdm" if using GNOME Ubuntu, or "kdm" if using kubuntu, and so on.)

Hi,

it is a VPN client with multiple VPN clients.
Kind of a VPN concentrator. But this is not
important. It is a headles system.
I am looking for the best solution
to use other systems via this box with x2go
but also use the box itself with x2go.

So I thought I could to from client computers:

1. Have one session with x2go to the box.
2. Create ssh forwardings on the box.
3. Connect with other x2go sessions via the box
   (ssh forward) to the systems behind the box.

What I do not know is, if x2go does have some
kind of proxy server. Meaning that I could connect
to the box and would have beeing presented a list
of hosts I could connect further via x2go.

Thanks a lot,
Matt

I don't follow you here.
Is this box a VPN server or a VPN client?
