Perhaps worth noting that on FreeBSD 2 (and iirc, 3) 'ipfw delete $rule'
only deleted the first of any set of same-numbered rules, ie you had to
issue multiple delete commands. This behaviour changed somewhere in 4.x
to a single delete command removing all same-numbered rules; I had to
modify several scripts at the time to accomodate that (sensible) change.
Cheers, Ian
