The rule-by-rule explanation of the ruleset was unnecessary; it did not
answer almost any of the questions I asked. My point is that the ruleset
that you propose will *not* mitigate virtually any exploit you can find
floating around, and as such is essentially useless. If you insist that
defending against nmap connect scans is a worthwhile goal, then we may
simply agree to disagree, but I don't expect you'll find many people who
 share your opinion.
