I've just started to look into traffic shaping and have the following environment. ISP--------eth1-LINUX-eth0----------intranet I want to mark all traffic coming from host 192.168.0.19 so that i can = pick up these packages and filter them before sending out on eth1/ppp0 I've tried things like: /usr/sbin/iptables -A POSTROUTING -t mangle -s 192.168.0.19 -p tcp \ -o eth0 -j MARK --set-mark 12 /usr/sbin/tc filter add dev eth1 protocol ip parent 1:1 prio 100 \ handle 12 fw classid 1:3 but this dosn't seem to work.....what's am I doing wrong or don't understand? -Svein Foss=E5en- -----------------------------------------------------------------------= ------------------------ This is Unix land.
