>Description:
By default if you natd_interface="out0" into your rc.conf it makes the
ipfw rule if natd_enable="YES" and then it makes the natd flag -n out0
this is good but if you want to make another IP the nat IP, you have to
make natd_interface="192.168.0.1" or whatever, but if that's not your
external interface, the ipfw rule is wrong and doesn't work. I have an
aliased IP that I want my nat traffic to leave as so, I set the
natd_flags="-a 192.168.0.2" and my natd_interface="out0" and then I needed
to edit /etc/rc.network, to look for that and not reduntantly
set -n to out0 as well as -a to 192.168.0.2
