Hi,
I fully agree with you. it must be very helpful during the
configuration, especially in your network scenario.
Maybe, you can try to implement a script to do that, update the ipfw3
whenever the IP changes.

Thats from the ipfw manual, not the ipfw3 manual. ipfw3 doesn't
support that syntax in the nat config. Looking at the source, it
parses the ip with inet_aton, which only accepts ips in the form
xxx.xxx[.xxx[.xxx]]
Just curious if you've tried it anyway. Might be an undocumented
feature. Or maybe you can assign an alias ip to the interface and use
that ip for natting to.
