I want an advise, because I don''t know much about lartc, I am using
htb.init.<br>
What I want to accomplish:<br>
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.<br>

<br>
<br>
If I understand corectly I must:<br>
<br>
1. include both eth0 and eth1 in traffic control: eth0 will limit
download and eth1 will limit upload from lan host perspective<br>
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<br>
<br>
Are any other issue to take in account here?<br>
<br>
<br>
Thank you.<br>
