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

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,
