Your local X server listens on tcp port 6000 + display number (usually
0).  You need to allow this traffic through your firewall.  Make sure
you only allow traffic from the Matlab server's IP address and *only*
when you want to use it.  You'll also need to use xauth to allow the
remote box to connect.

An even better solution would be to use ssh with x11 forwarding enabled.
It will automatically set $DISPLAY and tunnel the traffic so that you
don't need to make a hole in your firewall.  All connections to your
local X server will originate from the local ssh process with source
address 127.0.0.1, with no need for any holes in your firewall and no
need to play with xauth.


Cheers.
