I use an cable modem link, with an fixed IP adress, my out interface is eth0 and inside interface is eth1.
I'm trying to count the trafic my inside machine are making. Can you help me, because my script doesn't seam to work
whatever rule you setup with iptables it will count all data going through
let say you wanna know howmuch www you are using do this
iptables -I FORWARD -p tcp -s 192.168.1.0/24 --dport 80
or how much data comes in through http
iptables -I FORWARD -p tcp -d 192.168.1.0/24 --sport 80
then do
iptables -L FORWARD -v
and you will get all counters
You want to zero counters do
iptables -Z FORWARD
please note that you don't even need to do any jump (-j SOMEWHARE) -- don't do -j ACCEPT, because it may mess up your firewall. Also make sure to include your counter before forwarding rules, otherwise won't count
