Hi, I think that writing custom conntrack helper module which can be used to mark packets created by p2p software is the only solution acceptable in my case. I am also thinking about purchasing cheap E1 link and use it for p2p trafic. Two months ago I was thinking about writing such a module. Anyway, I didn't do anything because of lack of time and knowledge. I would like to be informed about your progress though. I also offer my help with testing. I think described module would be very usefull for large number of netadmins. RK
