Considering that I have used IPFW since FreeBSD > version 2 or something or another these fancy features have not always > been around :) 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
