Quick+easy port redirect

[Tuc at T-B-O-H.NET]

Hi,

	Is there a quick/easy (cookbook?) way to do port
redirects. Basically I want that anything that leaves 
a specific interface to any ip on port 80 go to 
192.168.0.1 port 87.

	I'm using ipfw for some other things so it has to
work and play well with that.

			Thanks, Tuc
