hi..i posted this message sometime back.. can pls someone help me with it.. i basically want traffic to be restricted for all server outside my network ie. 4e.g 64kbps for internet but 512kbps for my lan servers(web/smtp).. i though of doing this(as the script will tell u)--mark packets with iproute & restrict the traffic with iprote2(lan-web or smtp)..if no mark then pass thru the default bandwidth for the ip group !! the linux box is always handling 1Mb+ traffic from eth0(net interface).. awaiting some guidance for u Gurus there... arindam haldar Message: 6 Date: Fri, 04 Jan 2002 11:24:30 +0530 From: Arindam Haldar <ahiam@yahoo.com> To: Stef Coene <stef.coene@docum.org> Cc: lartc@mailman.ds9a.nl Subject: Re: [LARTC] iptables mark & iproute related ! hi, Stef Coene wrote: > On Thursday 03 January 2002 15:17, Arindam Haldar wrote: >>hi >>i did those test & as i said in my last mail there is trafic passing thru >>ir bytes counter r increasing but the tc command doesnt show any >>restircition. seem like marked pkts r not going thru the iproute >> > Sorry, you wrote to encrypted for me to understand everything [;-)] > If I understand correctly, everything works if you use CBQ & SFQ, but the fw > filter is not working like it should be ?
