That's the wrong procedure, you should not set DISPLAY yourself, ssh takes care
of that, and the value of DISPLAY is not <your client IP>, ssh will set it to
<your server IP>:10 or similar.

That's what happens when you set DISPLAY wrong, in this case there is a firewall
 that prevents direct connections.  Ssh doesn't use direct connections, it
tunnels the X protocol over the same connection you used to log-in.
