LARTC - May 2005 - newbie downloading not working

Hi guys

Finally , after reading a lot of docs from larc/opalsoft/etc, I decided
to start learning some QoS

First of all I''m trying to shape only download from a
iptables+squid+qos
machine for 4 machines at LAN ( eth0)

Can anyone help me , cause it is not working properly..

If you want to shape traffic from the internet to squid then you need to 
use imq (www.linuximq.net) set in kernel config to hook after prerouting 
nat. The traffic to squid will still have your internet address not 
192.168.0.1.
