Of course, each script can be tuned. Some remarks: - you are only shaping traffic leaving eth0, if you add class/filters to eth1, you can also shaping traffic leaving eth1 - you are shaping traffic leaving eth1 because you are shaping traffic entering eth0 with the ingress qdisc. but using htb/cbq for shaping gives you much more control. - try http://docum.org/ for other/more information.
