Hi, I have done this setup to give the machine 192.168.1.4 (masqueraded over dialup) the highest priority: #! /bin/bash WHAT="add" iptables -A PREROUTING -i eth0 -s 192.168.1.1 -t mangle -j MARK --set-mark 1 iptables -A PREROUTING -i eth0 -s 192.168.1.4 -t mangle -j MARK --set-mark 4 tc qdisc $WHAT dev ppp0 root handle 1: prio bands 3 priomap 0 1 2 tc qdisc $WHAT dev ppp0 parent 1:1 handle 2: pfifo limit 1024 tc qdisc $WHAT dev ppp0 parent 1:2 handle 3: pfifo limit 1024 tc qdisc $WHAT dev ppp0 parent 1:3 handle 4: pfifo limit 1024 tc filter add dev ppp0 protocol ip parent 1:0 prio 0 handle 4 fw classid 1:2 tc filter add dev ppp0 protocol ip parent 1:0 prio 2 handle 1 fw classid 1:3 and it is working because form the stats I can see the packets are flowing: [root@xxx /root]# tc -s -r qdisc show dev ppp0 qdisc pfifo 4: limit 1024p Sent 42374 bytes 804 pkts (dropped 0, overlimits 0) qdisc pfifo 3: limit 1024p Sent 16535 bytes 381 pkts (dropped 0, overlimits 0) qdisc pfifo 2: limit 1024p Sent 589 bytes 10 pkts (dropped 0, overlimits 0) qdisc prio 1: bands 3 priomap 0 1 2 2 1 2 0 0 1 1 1 1 1 1 1 1 Sent 59498 bytes 1195 pkts (dropped 0, overlimits 0) There is just 1 problem, the prioritization is not working. When I start downloading FTP on on the machine 192.168.1.1 , wait 20-30 secs and start another FTP session on 192.168.1.4 it does not gets the full bandwidth as it should get. What could be wrong? One workstation is linux (.1) , other is Win98 (.4), I don't know if this could be the issue. Thanks in advance Nikolai
