U can try and this. Put ip's how u want, and then use ipfw+natd, with
natd configured how i explain at previous message. In ipfw rules u
need to have an rule like:
100 natd ip from any to any
Shoul be work but i think that u need to manipulate and routing
table, because packets need to know where to go.
For that try to set this in rc.conf (but i think that u have already
set that)
defaultrouter="192.168.1.2"
gateway_enable="YES"
where 192.168.1.2 (for example)is ip of external interface on your firewall.
