Subject: Re: IPFW Firewall NAT inbound port-redirect
We're not talking about natd. The question was about the use of ipfirewall nat.

NATD and IPFW work together. It's a little hard to explain in this format so as
Dan suggests, you should read the manpage on each. Also, do some google
searches
and you will find many helpful articles. But take my word for this, you can do
exactly what you want with IPFW+NATD. There are those who will probably promote
PF as the firewall of choice as well. It all depends on what you become
familiar
with.
