Here is how I do it.  Works perfectly.

#!/bin/bash
#shaping passive and active outbound ftp traffic on an internal computer 
without affecting inbound and lan speed

# mark the outbound passive ftp packets on ports 50000-51000
iptables -t mangle -D OUTPUT -o eth0 -j MYSHAPER-OUT 2> /dev/null > 
/dev/null
iptables -t mangle -F MYSHAPER-OUT 2> /dev/null > /dev/null
iptables -t mangle -X MYSHAPER-OUT 2> /dev/null > /dev/null
 
iptables -t mangle -N MYSHAPER-OUT
iptables -t mangle -I OUTPUT -o eth0 -j MYSHAPER-OUT

iptables -t mangle -A MYSHAPER-OUT -m mark --mark 0 -j MARK --set-mark 20
iptables -t mangle -A MYSHAPER-OUT -p tcp --sport 59999 -j MARK 
--set-mark 26
iptables -t mangle -A MYSHAPER-OUT -p tcp --sport 50000:51000 -j MARK 
--set-mark 26
iptables -t mangle -A MYSHAPER-OUT -p tcp -m length --length :64 -j MARK 
--set-mark 30

# clear it
tc qdisc del dev eth0 root

#add the root qdisk
tc qdisc add dev eth0 root handle 1: htb default 20

#add main rate limit class
tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit

#add leaf classes
tc class add dev eth0 parent 1:1 classid 1:2 htb rate 100mbit
tc class add dev eth0 parent 1:1 classid 1:3 htb rate 40kbps

tc class add dev eth0 parent 1:3 classid 1:31 htb rate 30kbps ceil 
40kbps prio 2
tc class add dev eth0 parent 1:3 classid 1:32 htb rate 10kbps ceil 
34kbps prio 1

#filter traffic into classes
tc filter add dev eth0 parent 1:0  prio 0 protocol ip handle 20 fw 
flowid 1:2
tc filter add dev eth0 parent 1:0  prio 0 protocol ip handle 26 fw 
flowid 1:31
tc filter add dev eth0 parent 1:0  prio 0 protocol ip handle 30 fw 
flowid 1:32
