Hi I have set of rules that doing upload/download stats for my NATed network (10.0.0.0/8): # Marking $IPTABLES -t mangle -A FORWARD -p tcp -j CONNMARK --restore-mark $IPTABLES -t mangle -A FORWARD -p tcp -m mark ! --mark 0 -j ACCEPT $IPTABLES -t mangle -A FORWARD -p tcp -m ipp2p --ipp2p -j MARK --set-mark $P2P $IPTABLES -t mangle -A FORWARD -p tcp --dport $FTP_PORT -j MARK --set-mark $FTP $IPTABLES -t mangle -A FORWARD -p tcp --dport $SSH_PORT -j MARK --set-mark $SSH $IPTABLES -t mangle -A FORWARD -p tcp --dport $TELNET_PORT -j MARK --set-mark $SSH $IPTABLES -t mangle -A FORWARD -p tcp --dport $SMTP_PORT -j MARK --set-mark $SMTP $IPTABLES -t mangle -A FORWARD -p tcp --dport $HTTP_PORT -j MARK --set-mark $HTTP $IPTABLES -t mangle -A FORWARD -p tcp --dport $HTTPS_PORT -j MARK --set-mark $HTTPS $IPTABLES -t mangle -A FORWARD -p tcp --dport $POP3_PORT -j MARK --set-mark $POP3 $IPTABLES -t mangle -A FORWARD -p tcp --dport $IRC_PORT -j MARK --set-mark $IRC $IPTABLES -t mangle -A FORWARD -p tcp -j CONNMARK --save-mark Rules above (IMO) marks specified trafic traveling through FORWARD chain, and this is only traffic from localnet <-> internet, not from localnet <-> linuxbox. Ok, now i make chains for counting uploads/downloads from/to my lan. $IPTABLES -t mangle -N statsin $IPTABLES -t mangle -N statsout My internet interface is ppp0 ($INET_IF), and lan is connected to eth0 ($LOCAL_IF). So, with rules below I send packets leaving my box with ppp0 to statsout chain, and with eth0 to statsin. $IPTABLES -t mangle -A POSTROUTING -o $INET_IF -j statsout $IPTABLES -t mangle -A POSTROUTING -o $LOCAL_IF -j statsin And here is real counting. Note, that $OTHER is for not marked packets. $IPTABLES -t mangle -A statsin -m mark --mark $P2P $IPTABLES -t mangle -A statsin -m mark --mark $FTP $IPTABLES -t mangle -A statsin -m mark --mark $SSH $IPTABLES -t mangle -A statsin -m mark --mark $SMTP $IPTABLES -t mangle -A statsin -m mark --mark $HTTP $IPTABLES -t mangle -A statsin -m mark --mark $POP3 $IPTABLES -t mangle -A statsin -m mark --mark $IRC $IPTABLES -t mangle -A statsin -m mark --mark $OTHER $IPTABLES -t mangle -A statsout -m mark --mark $P2P $IPTABLES -t mangle -A statsout -m mark --mark $FTP $IPTABLES -t mangle -A statsout -m mark --mark $SSH $IPTABLES -t mangle -A statsout -m mark --mark $SMTP $IPTABLES -t mangle -A statsout -m mark --mark $HTTP $IPTABLES -t mangle -A statsout -m mark --mark $POP3 $IPTABLES -t mangle -A statsout -m mark --mark $IRC $IPTABLES -t mangle -A statsout -m mark --mark $OTHER Ok, this works fine for me. But there is one thing, that wondering me. I want to count only traffic from lan <-> internet. But these rules: $IPTABLES -t mangle -A POSTROUTING -o $INET_IF -j statsout $IPTABLES -t mangle -A POSTROUTING -o $LOCAL_IF -j statsin should also match packets generated on linuxbox destined to lan or internet. Is that true? These packets are not marked, so my rules count them as $OTHER. I dont want count these packets, so I wrote 2 new rules $IPTABLES -t mangle -A FORWARD -s 10.0.0.0/8 -j statsout $IPTABLES -t mangle -A FORWARD -d 10.0.0.0/8 -j statsin but this dont work :( So how can I count trafic only from lan <-> internet?
