I am currently working on a not so simple firewall setup on a modern machine (Xeon, Gigs of memory, SCSI subsystem). As part of it, I would like to know various "event" statistics.Questions I would like to answer is "How many hits on port 1433 have i got, and how is that distributed amongst the machines". Think pivot table data. Is there some way to get netfilter to collect rule hits (like with no -j clause) for a each port/ip-address individually within a range ? Other than creating thousands of lines of rules and add them to my "firewall-startup" script (which is currently slightly less than 80 rules). I have thought of just logging all traffic and running it through a userspace program via syslog-ng, but frankly I worry about performance (the firewall should be able to filter at least the 100Mbps connection, it currently sits on) under flooding. Your thoughs are apprieciated :) Svenne
