Hi all, I've been trying to do the above and read everything I can find on Google on the subject, but something seems to be going wrong. I tried the following sample rules in iptables (initially I just set the first one, but I added more as my desperation escalated): iptables -t mangle -A PREROUTING -p icmp -j MARK --set-mark 1 iptables -A FORWARD -p icmp -j MARK --set-mark 1 iptables -t mangle -A POSTROUTING -p icmp -j MARK --set-mark 1 With the following in my traffic shaping script: tc filter add dev eth0 parent 1:0 protocol ip prio 1 handle 1 fw classid 12:0 The problem is that all ICMP traffic is going out of the default queue (classid 15:0) even though the firewall is catching it (checking the packet counts with 'iptables -t mangle -L -nvx' and 'iptables -L -nvx' shows packets were being caught). So, why are the filters not catching the packets? What obvious mistake have I made? :) Many thanks for any help, Mark Lidstone IT and Network Support Administrator BMT SeaTech Ltd Grove House, Meridians Cross, 7 Ocean Way Ocean Village, Southampton.
