Hmm, I'm brand new to both tc and the list, so forgive me if I'm uttering nonsense :) The example below seems good to me if eth1 is the interface connected to the side your clients are on, not the side the ftp servers are on. Are u sure that is the interface setup you have? I have done a similar setup, but based on ip-range. I both used fw marks and route realm marks and that worked in both occasions. serge. -----Original Message----- From: David Coello [mailto:dcoello@quarkinside.com] Sent: Wednesday, December 11, 2002 7:16 PM To: lartc@mailman.ds9a.nl Subject: Re: Bandwidth by port Hi But why the code of above doesn´t work?
