You don't have any filters? How do you redirect traffic to a class? > You need some filters to do so. The filters are there... if you take a closer look you'll that my copy/paste was falty... But I can tell you I solved the problem. I attched my solution below. Stef, you are right, my filters are not working... In fact I don't konow what I did wrong: for marking packets depending on their source I used ipchains -A output -p all -s 192.168.1.0/30 -m 1 tc qdisc del dev eth1 root tc qdisc add dev eth1 root handle 1: cbq bandwidth 10Mbit cell 8 avpkt 300 mpu 64 tc class add dev eth1 parent 1: classid 1:1 cbq bandwidth 10Mbit rate 72Kbit weight 7.2Kbit prio 7 allot 1514 maxburst 20 avpkt 300 bounded isolated tc class add dev eth1 parent 1:1 classid 1:3 cbq bandwidth 10Mbit rate 64Kbit weight 6.4Kbit prio 6 allot 1514 bounded isolated ip route add 192.168.1.8/29 via 192.168.1.1 realm 1 tc filter add dev eth1 parent 1:0 protocol ip prio 1 route to 1 classid 1:3 tc class add dev eth1 parent 1:1 classid 1:2 cbq bandwidth 10Mbit rate 14Kbit allot 1514 cell 8 weight 1.4Kbit prio 7 maxburst 20 avpkt 300 split 1:0 bounded isolated ip route add 192.168.3.8/29 via 192.168.3.1 realm 2 tc filter add dev eth1 parent 1:0 protocol ip prio 7 route to 2 classid 1:2
