I wanna solve such a problem: When I see that byte counter on some chain reaches or exceedes any fixed value - then IMMEDIATELY insert into that cahin new first rule (e.g. -j DROP) or delete some rules from any other chain. Or more abstract - how can can discover that byte counter is higher than smth without "polling" chains? Sorry for sending such a mail into announce, developers and user maillists but I need help as soon as possible. :)
