I presume you mean "RADSL", since that's the variety of DSL offered
around here.  :-)

If you're using NAT, you don't.  You could set up something on your NAT
machine so that the incoming X connections are forwarded to your
internal machine, but your best bet would probably be to use SSH
to connect to CSU (check, but I think licensing would allow it for
SSH version 1.2 and older), and have it proxy the X connection
for you.

If the SSH licensing bites you, you could use the dxpc software to set up
a similar tunnel (and you get REALLY good compression over it too).  This
is probably the preferred way to do it, except that it doesn't offer
encryption.  It DOES offer GREAT X compression though.
