Minor nit - I think you meant to write "stupid" not "outdated."
As far back as I can remember (and that's a long way!) some of
us have been saying that permit log entries are more important
than deny. In fact, the first codebase of my first firewall didn't even
bother logging denys because, at the time I felt that a deny log
message only meant "the firewall is working."
