andreas first thanks for the answer and the advices. well. let me say some things: inspite of saying that i have 600kbit for 20 users, it is really rare to have more than 7 at the same time and about that you say take a look at ipp2p or l7-filter: errr, can they identify when a user changed edonkey or any other p2p default port and limit such packet even so ???? ----- Original Message ----- From: "Andreas Klauer" <Andreas.Klauer@xxxxxxxxxxxxxx> To: <lartc@xxxxxxxxxxxxxxx> Sent: Sunday, October 17, 2004 10:19 AM Subject: Re: htb > Am Sunday 17 October 2004 14:42 schrieb James Lista: > > 600kbit ------------ 50% for port 80 > > 30% for port 25 and 110 > > 20% for the rest > > Sure, that's possible.
