It's an in-game feature, which doesn't use extra protocols to retrieve ping, hence counter-trike server uses port 27015 to both game packets and "ping-in-game"-packets. And besides, it wouldn't make any difference to only prioritize the "ping-in-game"-packets, even if you could - the game would still lag as without traffic control. > this is what i try, beacouse i dont realy play the game, i generate > trafic to saturate the link, and ping from shell from an externat host In which case, you should check if your downstream is not chocking. Even if you shape outgoing packets, you can still get get bad pings, if your downstream is running at max. -- Theepan
