You need to make sure you have X11 forwarding enabled with ssh.

You can do this by modifying the sshd_config file or by using the -X or
-Y options when you startup ssh.

You will also need to use xhost to allow another system to send a
dispaly to your system.  xhost + opens up permissions to all systems. 
You can refine that to allow specific systems.  

It would help if you posted the specific error your are getting as well
as specific commands you are using to attempt this.

If you use ssh to do the x11 forwarding for you you don't need to mess
with iptables as long as you allow ssh to connect to the remote system.
