Hello, it's me again, finally p2p traffic is getting shaped, but now I still have one problem: download seems to be affected when shaping the traffic, ack packets are in the interactive queue too, as someone adviced me, what fixed the problem was to change the rates, to match (the sum of all subclasses) the root class rate, and to give the p2p class a very low rate (1k actually) and 75% of the bandwidth for the ceiling. Well as I said this is working, but downloading seems to be affected to, I get pretty low rates (this doesn't happen when I'm not shaping the traffic, but then I can't do anything else but bittorrent). Does anyone have a clue on why's this happening?

Thanks to everyone that help me, I really appreciate it.

Shaping upload will affect bittorrent downloads as it it part of the protocol for peers to favour the connections that are giving them the highest rates.

That may not be the only thing though, if you are marking with ipp2p then the acks for the download will be queued with the upload traffic - this happens with the ones that get piggybacked anyway, but I let empty bt acks have priority over those.

It would help if you make the bt queue fairly short.

Andy.
