You need to configure the NAT (Network Address Translation) on your router
to directect any incoming packets for the port you're using for your X
display. If you're setting your DISPLAY parm to XXX.XXX.XXX.XXX:0, the
port would be 6000. It's normally the display ID (ie :n) plus 600.
(..xxx:1 would be 6001).
