Sorry if didn't reply you as expected Currently I use iptables to monitor how many bytes and packets each client has transmitted: Each client has an ACCEPT rule that matches their IP and MAC address I can see the byte and packet counters with iptables -L -n -v then, I use a script to parse this output and feed the apropriate RRD. Previously, I used to parse the output of tc -s class ls dev ifb0 which gave me almost the same result On 9/6/07, Ming-Ching Tiew <mingching.tiew@xxxxxxxxxxx> wrote: > > From: "Marco Aurelio" <marco.casaroli@xxxxxxxxx> > > > If you use IFB or IMQ you can shape the outgoing WAN traffic before NAT > > > > I am not sure if I understand this reply or the reply seems to me, > is not replying to my original question. > > I am asking how to collect statistics about LAN users with respect > to their WAN usage, with LAN IP as the breakdown. > > I am not asking how to do traffic shaping.
