[PLUG] Any Win2000 based X server can go through firewall?

[Zhang Tianpei]

I am sharing a cable modem with my roomate, by a router, and so behind a
firewall.

Using ssh in Linux, I can easily connect to a remote machine and run X.
However, I am wondering if there is any Window 2000 based X server that
can go through the firewall?(I tried XWin32, but have to use IP forwarding
, and so only one machine can use). Thanks a lot for your guys' kind
advice.
