mangle p2p traffic

i try to mark packets from all p2p with no success.
chain=forward action=mark-packet new-packet-mark=P2P passthrough=no p2p=all-p2pi have tried prerouting chain also.

I see in uTorrent that it has downloaded some mb but winbox shows to have marked some kb only.

How can i mark p2p traffic? I use version 6.4.

I would try searching the forums: https://encrypted.google.com/search?q=+site:forum.mikrotik.com+block+p2p

i found info about how to block p2p. Layer7 seems to do the job. But i neet to mangle p2p so cant use them on queues for example, not to block them.

Ah, ok. Maybe these will be helpful:
