If it were me, I'd opt to use a separate RFC1918 on the WAN (albeit not a class C [though you could since they are expendable addresses]), and route with proper IP next hops. Something like: ifconfig ng0 inet 192.168.2.1 netmask 255.255.255.252 route add -net 192.168.1.0/24 192.168.2.2 route add default <internet> ifconfig ng1 inet 192.168.2.2 netmask 255.255.255.252 route add default 192.168.2.1 This just seems cleaner to me.
