Hi, I just bought a new router Draytek 2800G and im trying to setup the QoS on it. Can anyone please explain DiffServ to me, ive looked wikipedia etc but dont get it? The router has AF Class1 (High Drop) AF Class1 (Medium Drop) AF Class1 (Low Drop) .... AF Class7 (Low Drop) & IP precedence 1 .... IP precedence 7 & EF Class Im trying to setup so that DOD/CS get highest priority, then voip, then streaming music and downloads / etc are at the very bottom. Anyone any ideas? Thanks N4N01D
