dummynet + ack http

[bogdan oprea]

i was wondering if the following scenario is possible:
i am running a small isp with upto 20Mbps download speed and 10Mbps upload speed
i want to prioritize http traffic (and dns, ping, possibly voip and some games) over other traffic (p2p etc)
i know that this is done with queues but i don't know the right weights for the queues
3 queues i think should be enough: queue1-ack http, queue2-ack-other, queue3-rest of the traffic

so if anyone knows what are the weights of the queues or a ipfw.rules example please help me
