--MYWAYBOUNDARY_000__def60337a6667d3acb2b77c2d7b3816d Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Hi Thanks for your reply.One question - The lartc documentation says - that in a NATed environment you should mark packets in the PREROUTING stage while you have done in FORWARD stage - is that ok ?Actually, I had asked this question earlier in this forum and I was told to mark packets in the PREROUTING stage. Similarly while receiving packets (downstream) on eth1 ; which stage should I mark packets ? I am not that conversant with iptables.

The network diagram is as given below.Yes indeed! All you need is create the appropriate classes on thenetwork-interfaces. As I'm only using HTB and iptables I can give you just a HTBexample:> eth1 : internal interface> eth0/ppp0 : outgoing interfaceOk, let's say you create the following classes according to yourinformation:eth1: -1:1 512kbps (user1)-1:2 1Mbps (user2)ppp0:-2:1 128kbps (user1)-2:2 256kbps (user2) user1's ip is 192.168.0.1user2's ip is 192.168.0.2The iptables rules would be:#marking packetsiptables -t mangle -A FORWARD -s 192.168.0.1 -j MARK --set-mark 1iptables -t mangle -A FORWARD -d 192.168.0.1 -j MARK --set-mark 1iptables -t mangle -A FORWARD -s 192.168.0.2 -j MARK --set-mark 2iptables -t mangle -A FORWARD -d 192.168.0.2 -j MARK --set-mark 2#putting packets in HTB classesiptables -t mangle -A POSTROUTING -o eth1 -m mark --mark 1 -j CLASSIFY--set-class 1:1iptables -t mangle -A POSTROUTING -o eth0 -m mark --mark 1 -j CLASSIFY--set-class 2:1iptables -t mangle -A POSTROUTING -o eth1 -m mark --mark 1 -j CLASSIFY--set-class 1:2iptables -t mangle -A POSTROUTING -o eth0 -m mark --mark 1 -j CLASSIFY--set-class 2:2As I don't know your setup you can make sure that nothing goes wrong byadding the incoming and outgoing interfaces at the marking part like this:iptables -t mangle -A FORWARD -i eth1 -o ppp0 -s 192.168.0.1 -j MARK--set-mark 1For putting the packets into HTB classes you can also use tc filter ifyou're not familar with CLASSIFY.Hope that helps!M.-- COMPUTERBILD 15/03: Premium-e-mail-Dienste im Test--------------------------------------------------1.
