You know SQUAT about filtering on Linux. You want a bridging solution? 
Then forget about Linux. Even FreeBSD will perform better at bridging 
firewalling than Linux and OpenBSD is the best performer available.

That ipset solution came way after OpenBSD and pf had such a feature and 
which was already mature and stable too. I should know, I tested ipset 
while it was still new some years ago.
