Real IP under NAT

[DerAlSem]

Hello everybody.

Need any info (man page, forum topic, etc) regarding making a DMZ host
under FreeBSD (5.3).

I've 5 external (real) IP, one is assigned on external if. Also there
are 20 internal computers with 192.168.0.* ip's (NAT+IPFW). I need to assign one
of that computer an external ip. Somebody told me, that it can be done
with ARP-proxy, but i couldn't find any info on that. 10x in advance.
