from an example off the website, ive change a couple of values... what
do i need to start limiting to *only* port 80

#!/bin/sh
RATE_TOT=256kbps
RATE1=128kbps

IP=210.54.175.12

DEV="dev eth0"
OPTION="allot 1514 maxburst 20 avpkt 1000"

tc qdisc del $DEV root
tc qdisc add $DEV root handle 10: cbq bandwidth 10mbit avpkt 1000
tc class add $DEV parent 10:0 classid 10:1 cbq bandwidth 10mbit rate
$RATE_TOT $OPTION prio 3 isolated
tc class add $DEV parent 10:1 classid 10:10 cbq bandwidth 10mbit rate
$RATE1 $OPTION prio 3 bounded

tc filter add $DEV parent 10:  protocol ip prio 3 handle 1 fw classid
10:1
tc filter add $DEV parent 10:1 protocol ip prio 3 handle 1 fw classid
10:10

iptables -F
iptables -X
iptables -N acc_0
iptables -N acc_1
iptables -A OUTPUT -t mangle -p tcp --dport 2000 -d $IP -j MARK
--set-mark 1
iptables -A OUTPUT -p tcp --dport 2000 -d $IP -j acc_0
