LARTC - Apr 2006 - QoS Solution for an ISP - Need help on my build tryout

Hello all,

    I am doing many trys on put a QoS Solution to work at my ISP/WISP. I 
have this network topology:

router <> eth0.srv <> eth1.srv <> clients

    I just want to make that ALL http, mail, ssh and icmp traffic have 
preference in any instace. So, what I tryed to do was this:

My link has 3096 Kbps upload and 3096 Kbps download (it is a ppp from a 
telecom)

    I set a class (tc class) in both interfaces making all trafic going 
to default class 1:20 that has prio 5. In this class I put a max 
velocidade of 2500 Kbps. Them I made a filter that will direct all 
marked (with mark 40) packets to class 1:10 in both interfaces and this 
class has prio 1 and parent to 1:0. I have marked packges like this:

iptables -t mangle -A PREROUTING -p tcp -m tcp --dport 80 -j MARK 
--set-mark 40
iptables -t mangle -A PREROUTING -p tcp -m tcp --sport 80 -j MARK 
--set-mark 40

    I made this for every port and every protocol I want but I could not 
make this QoS works fine. This is still too slow (http browsing).

    Can someone help me?

Att,

Nataniel Klug
