    Hello

         I need to count p2p downloads and uploads to/from my
         small NATed network. I have all i need - ipp2p module for
         iptables, CONNMARK etc. (2.4.26)

         Here is an example (little modified) from ipp2p site:

         iptables -t mangle -A PREROUTING -p tcp -j CONNMARK --restore-mark
         iptables -t mangle -A PREROUTING -p tcp -m mark ! --mark 0 -j ACCEPT
         iptables -t mangle -A PREROUTING -p tcp -m ipp2p --ipp2p -j MARK --set-mark 1
         iptables -t mangle -A PREROUTING -p tcp -j CONNMARK --save-mark

         iptables -t mangle -A POSTROUTING -m mark --mark 1 -j ACCEPT

         With this i can count all p2p traffic passing my linux box, but i
         need to separate downloads and uploads. Any suggestions how i can
         do that? My natwork - 10.0.0.8/8
