that's an alternative.  i'll have to figure out how with which script
lang (for lowest overhead on an embedded box ...).

thanks.

shame.  i certainly can't speak to the performance/tech issue you
raise, but, this (human-readable labels in my logs) is one of the very
few things i *do* miss from the 'old' iptables-based solutions i
migrated away from ...

the script should be an alternative.

thanks again.
