	I'm not positive that this will address your problem, but they may be
work a look :

bounce-1.0 in the ports collection, from the description there :

	A little program to bounce tcp connections to another machine/port.
	By default it listens on port 1523.

fwtk-2.1 in the ports collection also has tools for creating firewalls,
and I think a method for port fowarding is in there also.  I think there
may be some license restrictions on it's use.

I've never actually used either of these so I can't say if they will do
the trick or not.  I think there are more than a handle full of programs
out there similar to the bounce program listed above.

In the past I've successfully used nat to forward requests to other
machines, usually on the same port, but that shouldn't make a
difference.
