I'm out of public IP addresses.

I have iFolder, Groupwise, and a host of other services running on my
server
Mars.

I have my NDPS manager running on my server Saturn.

Mars has a NAT'd public-private IP address with all of the ports I
want to
exposed available to the Internet - including 443. However I really
don't
want to move my NDPS manager over to Mars if I can help it, yet all of
the
iPrint URLs point to Mars.

Is there a way that I can tell MARS to forward all iPrint requests
coming
from the Internet to Saturn? When I click on "Install Printers" on
Mars, it
barks at me stating: "iPrint service is currently not active at this
location".

Indeed, IPPSRVR.NLM isn't loaded on Mars- it is loaded on Saturn (my
NDPS
manager).

What are my options? Is it just a matter of loading IPPSRVR.NLM on
Mars?
Does iPrint have "forwarding" functionality built in? Am I locked-in
to
getting another public IP just to run iPrint?

Again, I really don't want to move NDPS manager over to Mars. It's
not the
most stable server in my tree.

Thanks for any ideas,

Brian
