Could it be as simple as this? ->
00100 divert 8668 ip from 208.194.173.xx:80 to 192.168.0.7:80 via dc0
I wonder about the line number though, my rc.firewall
rules do not have line numbers, they start with /sbin/ipfw,
so do I leave those off and replace them with /sbin/ipfw
when I add the necessary line to my rules?
