Forwarding X across firewall

I would like to forward X sessions (XDMCP and DISPLAY stuff) across my
firewall machine, which is masquerading a bunch of internal machines with
2.2.x kernel.

ssh does the job transparently, and it's great. However, for the external
servers without ssh, I am wondering how to re-route X to specific
machines. If I use rinetd to route all 5999-600x ports for X, it will have
to be to a specific machine - and this is not what I want.

Of couse if I

remote> export DISPLAY=myfirewall.domain.com:0

on the remote host, then the display is sent to the firewall machine and
not to the internal host that initiated the connection.

Any insight would be appreciated, and thanks,

Martin
