I want an advise, because I don't know much about lartc, I am using
htb.init. 
What I want to accomplish: 
I have a RH9 as gateway in a network with 30 computers. RH9 make SNAT
for them to go out on internet, and I want to be able to assign
different bandwidth to different computer in local network.

If I understand corectly I must: 
 
1. include both eth0 and eth1 in traffic control: eth0 will limit
download and eth1 will limit upload from lan host perspective 
2. because on eth1 I make SNAT I cannot differentiate by source IP
different classes, all packets will have the public IP as source after
SNAT so I must MARK packets and different classes by this MARK 
 
Are any other issue to take in account here? 
 
 
Thank you.
