iptables counter

[epsilon_da]

hi.

I am finding some tool which uses the iptables counters and make statistics, like with vnstats but with the ports which i want to monitor.

I think this could be stripped with normal tools like grep, sed, cut, etc. directly from iptables -L -v -n -t mangle, but it turns dificult when you have lots of ports or ips which you want to monitor. The best way, i think is tell to iptables to count to a separate file on /proc/net/whatever, maybe some new target like

${iptables_bin} -A POSTROUTING -o ${LAN_IF} -t mangle -j COUNT --name LAN
${iptables_bin} -A PREROUTING -i ${LAN_IF} -t mangle -j COUNT --name LAN

and then look at the files on /proc/net/count/LAN

somebody know something like that?
i looked for account module but it makes counts depending on the ip who sends the packet.
