I'm not sure that FreeBSD withstand an over 20k rules of the form:
ipfw nat 3 config ip 100.1.2.3
ipfw nat 4 config ip 100.1.2.4
ipfw nat 5 config ip 100.1.2.5
ipfw nat 6 config ip 100.1.2.6
...
+ Two rules to handle each nat N
Probably need to somehow use nat tablearg, but I do not understand logic.
