Separate statistics/logging counters is fine, but i don't need per-rule limits, a global limit is ok --> sysctl -w for raising and ipfw zerolog (or reset) for resetting. And then ... securelevel == 3 I think it is better NOT to permit 'sysctl -w', 'ipfw *' AND a logging limmit, just process the logfile faster to avoid DoS > > > > We need more input from people who use the code, to make sure they don't > > depend on the current 'features', or can live with changes to them.
