Thnx. Well this solution will not work for me. Since the bandwidth is
already payed, I've interested to fill my backbone with traffic :-). The
problems are more during the peak time. If no other customer uses http,
nntp, vpn... then I don't care about p2p traffic. But I saw that the p2p
traffic is growing rapidly. Much more than any other traffic. So at the
moment I do queuing with ipfw/dummynet without any problem. This works
fine untile the p2p clients are starting to use port 80 more often. This
makes it very difficult for filtering. So I'm looking for a solution
for this specified problem. Frist I thought about snort. But I'm not
sure if this works very well with gigabit backbones.
