I can't do it better then you did :)Here are the rules Iam applying to control outgoing traffic at WAN(eth0) interface for public hosted services. Here actual Isp rate = 512Kbit, rate taken = 97% of 512Kbit, eth0 ip is 192.168.1.2

Pls let me know whether the above rules are framed correctly or can be
done in a better way.
Traffic Control is not taking place after applying the above rules. Here follows the test setup:-
1. The linux m/c 's eth0(100Mbits, WAN) is connected to 128 Kbits ADSL and eth1 to the LAN.
2. I tried doing traffic control for incoming(at eth1) and outgoing(at eth0) traffic using CBQ(above rules).
3. In LAN, I connected 3 m/c's(all linux).
4. The ISP rate taken is 97% of 128Kbits.
5. Bandwidth Monitoring is done by using IPTraf on each LAN m/c's.
I have few observations and queries, as follows:--
1. Here the ISP rate is fluctuating in the range of 21Kbits to 131 Kbits for 128Kbits ADSL.
2. I have not added any filter for the parent class. Is it required...? What happens if I add...?
3. Is "iptraf " tool OK for monitoring the distribution of bandwidth on each LAN m/c.
4. Whether shall I take outgoing and incoming ISP rate's in 30:70 ratio, i.e 30% if 128Kbits for outgoing Qdisc(eth0) and 70% for incoming
Qdisc(eth1). As 128 Kbits rate being asyncronous(ADSL).
Can you pls guide me where amI going wrong..?
