Lartc readers I have a peculiar problem with shaping and firewalling.
My tc rules work great, below is a smaller version: #Root tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 100 #Root Class tc class add dev eth0 parent 1: classid 1:1 htb rate 1024kbit quantum 20000 burst 15k #Class for each user tc class add dev eth0 parent 1:1 classid 1:2 htb rate 32kbit ceil 128kbit prio 0 quantum 20000 burst 15k tc class add dev eth0 parent 1:1 classid 1:3 htb rate 32kbit ceil 128kbit prio 0 quantum 20000 burst 15k ... # SFQ qdisc for each user class tc qdisc add dev eth0 parent 1:2 handle 12: sfq perturb 10 tc qdisc add dev eth0 parent 1:3 handle 13: sfq perturb 10 ... #Filters tc filter add dev eth0 protocol ip parent 1: prio 0 handle 2 fw classid 1:2 tc filter add dev eth0 protocol ip parent 1: prio 0 handle 3 fw classid 1:3 ... #iptables mangle rules iptables -t mangle -A POSTROUTING -o eth1 -d 192.168.0.1 -j MARK --set-mark 2 iptables -t mangle -A POSTROUTING -o eth1 -d 192.168.0.2 -j MARK --set-mark 2 ... #iptables allow forwarding on MAC address iptables -A FORWARD -o ppp0 -m mac --mac-source 00:0D:61:30:10:75 -j ACCEPT iptables -A FORWARD -o eth1 -m mac --mac-source 00:10:B5:01:AA:D0 -j ACCEPT ... Should note that the default policy of filter->forward is DROP. All other chains are defaulting on ACCEPT Now, no users can connect through the gateway. Our test traffic for the shapping works perfectly, but no internet traffic works. iptables -nvL output shows that the packets move through the forward chain in filter, but it doesn't reach the mangle table for marking the packets. It's as if the packets disappear... Anybody got some ideas? I still have to test the shaping using u32 matching, using iptables to do forwarding.
