How did you get it working?  I have been playing with natd for a couple of 
days now, and am having some problems.  I do the following:

	ipfw flush
	ipfw add divert 32000 ip from any to any via ppp0
	ipfw add pass ip from any to any

	natd -n ppp0 -verbose -dynamic -port 32000

Everything then talks fine both on the firewall machine, and from my work 
machine across the room, for 0-3 minutes.  After that, the logging on the 
console slows to a halt, and if I try to:

	ping prep.ai.mit.edu  (arbitrary choice 8)

I get:
	ping: sendto: No buffer space available

A little later the connection drops carrier, and then has to redial my ISP.
The interesting part is the same thing seems to occur when my network is 
completely idle.  Every 2-3 minutes carrier drops and it redials.

	TIA,
