&nbs= p; = ; = &= nbsp; =20 Hi,

I hope that somebody = could help=20 me. I have the following structure:

Internet ------- Linux gateway1 = ------------- Linux=20 gateway2 ----------- Clients

CISCO---------eth1----------eth0------------eth0--------------et= h1-------switch--------

I have to limit=20 the download bandwidth of those clients placed after Linux = gateway2=20 connected through a switch. I have used the latest "cbq.init"=20 script from iproute ftp site. I've created the files=20 for limiting every client for upload and for download. Then I = started=20 the script and I had the qdisc, classes and the filters = running. My=20 clients had the right limitations but at the eth0 interface from Linux = gateway2=20 I had a lot of traffic, most of which was dropped. = All clients'=20 requests generate a lot of traffic between Linux gateway1 = and Linux=20 gateway2.

After running the = script I=20 have at the eth0 interface on the Linux gateway2 the same = traffic as=20 if the filter wouldn't exist. Sometimes even more traffic. In that = case the=20 filters were useless. It's important for me to limit the entire = client=20 traffic from CISCO to the switch client connection.

A few days ago I = though that I=20 found the solution but it wans't the good one: to limit the upload that = much=20 that it will produce less download. Ok. The HTTP upload was=20 limited drastic and requests was marked with iptables=20 and the fw filter was applied. At first view all was fine. So I = made the=20 limitation to 4 Kbit upload for the HTTP requests. For small files the = filter=20 was acting fine. But for large files HTTP downloads (over 1 Mb) I had 8 = (even 9)=20 KB/s in Internet Explorer speed. I really need to limit the entire = download=20 bandwidth to max. 6KB/s.

What's wrong = ?

Thank you,

Liviu
