Assuming you are using OpenSSH (since you don't say), on the DMZ server,
set "X11Forwarding" to "yes" in /etc/ssh/sshd_config and send a HUP
signal to the ssh daemon to force a config file re-read. This will
transparently forward X11 connections from the server to your client's
Xserver through the SSH tunnel. Assuming you are allowing the inbound
SSH connection to the DMZ server on TCP port 24, you can just login via
SSH to the server and start up an x-based client, say "xterm". This
should work as expected. Make sure "UseLogin" is set to "No" in the same
config file (it should be by default); if it is set to "yes" this will
disable X11 forwarding.
