We have a WRT160NL router with OpenWRT 10.03, and a 60-70 Mbit connection (from ISP, don't ask why). This router can do 30-35 Mbit on ethernet(i mean cable)..ok!
There are ~7 PC's using this Wireless router, 6 through wifi (wep, because of the speed.. :\ ), 1 with cable.
Question: How can we limit P2P/torrent traffic, to have very-very-very-very low priority? I mean if someone downloads from torrent, the speed is getting about e.g.: ~0,5 Mbit/sec etc.
Without recompliing (i only want to use "stock" packages) are there any chances that i can do this? how?
max connection limiting? how?
topology:
ISP -> WRT160NL -> 7 clients (NAT, 192.168.1.0/24)..
I don't want to completely "disable" P2P/torrent traffic, I just want to slow them down, so the network would be usable even if several people use it, and e.g.: one of them is downloading st. over torrent. But if only e.g.: 1 person is using the network, then allow him to use all the bandwidth without limiting P2P.

I agree with Caleb that splitting the bandwidth is probably going to be the easiest, however, as a more roundabout solution, you might want to take a look at Micro Transport Protocol. uTP has been designed by the uTorrent guys to try and mitigate latency issues caused by BitTorrent which I assume is the root of your issue. In my experience it works quite well and there's a noticeable difference on my ADSL connection, for example.
In the free software ecosystem, uTP is supported by KTorrent (4.0+) and Transmission (2.30+). Vuze also implements it, but not on Linux. And, of course, the official uTorrent client supports it.
