If at all possible, I would still like to hear a suggestion as to how to
combine the two rules. From my pov, the first "allow" in rule 11 makes a
packet pass, provided there are less then 32 connections in total. Thus,
rule 12 never gets invoked (which, indeed, seems to be the case).
Someone suggested to me I was at fault for numbering the rules. Quite
frankly, that does not compute to me, as ipfw autonumbers anyway (in default
steps of 100, I believe). Seriously, I do not mind hearing how "all wrong"
my rules are; but, at the same time, I have not heard a proper way of doing
I appreciate suggestions,
