i use to forward about 200 machines through one IP (+ipfw2 to manage 
bandwidth). all works fine except no authentication of user is possible.

for NetBSD i wrote a simple program (identd replacement) that parsed
ipnat -l output and made and answer.

but under FreeBSD there is no thing similar to /sbin/ipnat -l with natd.

or maybe is? something that will output natd map table.
