	I have been stummped with this for a while; I thought it'd be 
relatively easy, but I have been unable to pull it off.

	I have a Linux box A that communicates with another Linux box 
over a VPN. I can access B from A without any problems. What I want to 
achieve is the following:

	In B there is a UDP application that listens for data on port p1. 
What I would like to do is to access this application from A, but using 
port p2, rather than p1 (don't ask why, please). I imagined this would be 
a simple thing to do with iptables, but I obviously overestimated my 
understanding of iptables.

	Any suggestions on how to proceed?
