LinuxQuestions.org - traffic shaping with htb.init

Im trying to setup some basic bandwidth control for my connection to avoid mostly upload saturation due to outgoing mail. I have a 128Kbps line, shared among several users, behind a firewall. Web browsing is done via proxy. I have the following line to redirect http requests to port 3128:

Code:

iptables -t nat -A PREROUTING -s $INT_NET -d ! $INT_NET -i $INT_IF -p tcp --dport 80 -j REDIRECT --to-port 3128

Also I have the following lines:

Code:

# In the NAT table (-t nat), Append a rule (-A) after routing

# (POSTROUTING) for all packets going out eth1 (-o eth1) which says to

# SNAT the connection.

$IPTABLES -t nat -A POSTROUTING -o $EXT_IF -s $INT_NET -j SNAT --to $EXT_IP



#Mangle OUTPUT

# 16 Minimize delay

#  8 Maximize throughput



$IPTABLES -t mangle -A OUTPUT -o $EXT_IF -p tcp --dport 21 -j TOS --set-tos 16

$IPTABLES -t mangle -A OUTPUT -o $EXT_IF -p tcp --dport 80 -j TOS --set-tos 8

$IPTABLES -t mangle -A OUTPUT -o $EXT_IF -p tcp --dport 53 -j TOS --set-tos 16

$IPTABLES -t mangle -A OUTPUT -o $EXT_IF -p udp --dport 53 -j TOS --set-tos 16



#Mangle PREROUTING

# 16 Minimize delay

#  8 Maximize throughput



$IPTABLES -t mangle -A PREROUTING -i $EXT_IF -p tcp --dport 21 -j TOS --set-tos 16

$IPTABLES -t mangle -A PREROUTING -i $EXT_IF -p tcp --dport 80 -j TOS --set-tos 8

$IPTABLES -t mangle -A PREROUTING -i $EXT_IF -p tcp --dport 53 -j TOS --set-tos 16

$IPTABLES -t mangle -A PREROUTING -i $EXT_IF -p udp --dport 53 -j TOS --set-tos 16

My htb.init ocnfig is the following:

Code:

file eth2

DEFAULT=100

R2Q=100



file eth2-2.root

DEFAULT=100

R2Q=100



file eth2-2:10.www

# www

RATE=100Kbits

CEIL=128Kbits

LEAF=sfq

RULE=*:80

RULE=*:8000

PRIO=1



file eth2-2:20.torrent

# www

RATE=64Kbits

CEIL=108Kbits

LEAF=sfq

RULE=*:6889

RULE=*:6888

PRIO=2





eth2-2:40.smtp

# outgoing mail

RATE=24Kbits

CEIL=33Kbits

LEAF=sfq

RULE=*:25

PRIO=4



file eth2-2:100.default

# default

RATE=16Kbits

CEIL=24Kbits

LEAF=sfq

PRIO=30

But basically this doesnt helps in the main problem: web browsing is terribly slow, loading some pages takes 1-2 minutes and downloading a couple of megabytes takes up to 6 hours. The torrent download is working fine, but even if I close it when rate reach 7-8Kb, http traffic does not improves at all, so where did that 7-8Kb went?
an somebody see some error in my configuration?
Im using Gentoo Linux 2007.0 with kernel 2.6.26.
