htb + tc + iptables strange problems

[ii95m]

Dear all,
In my machines, there are two interfaces (eth0 for internal, eth1 for internet), the machine is running masquerade.
I'm using kernel 2.6.6 love 4, iptables-1.2.9-r4 (compiled with extensions), iproute2 [2.6.7.20040608].
I've tried using kernel 2.6.7 (development gentoo)
The problem I'm having is like this:
if I make an iptables rules only using dport or sport, mark it with a marker, the htb works fine.
the problems occur only when I add source ip address, destination port, PREROUTING, INPUT, FORWARD rule, then the htb catches none of the mark, it goes to default class of htb.

here's my htb config:

#!/bin/bash

tc qdisc del dev eth1 root

tc qdisc add dev eth1 root handle 1: htb default 80 debug 3333333
tc class add dev eth1 parent 1: classid 1:1 htb rate 65kbit ceil 65kbit
tc class add dev eth1 parent 1:1 classid 1:10 htb rate 20kbit ceil 65kbit prio 3
tc class add dev eth1 parent 1:1 classid 1:20 htb rate 5kbit ceil 10kbit prio 0
tc class add dev eth1 parent 1:1 classid 1:30 htb rate 8kbit ceil 11kbit prio 2
tc class add dev eth1 parent 1:1 classid 1:40 htb rate 23kbit ceil 23kbit prio 1
tc class add dev eth1 parent 1:1 classid 1:80 htb rate 8kbit ceil 10kbit prio 4

tc qdisc add dev eth1 parent 1:10 handle 10: sfq perturb 10
tc qdisc add dev eth1 parent 1:20 handle 20: sfq perturb 10
tc qdisc add dev eth1 parent 1:30 handle 30: sfq perturb 10
tc qdisc add dev eth1 parent 1:40 handle 40: sfq perturb 10
tc qdisc add dev eth1 parent 1:80 handle 80: sfq perturb 10

tc filter add dev eth1 parent 1:0 protocol ip handle 1 fw flowid 1:10
tc filter add dev eth1 parent 1:0 protocol ip handle 2 fw flowid 1:20
tc filter add dev eth1 protocol ip parent 1:0 handle 3 fw flowid 1:30
tc filter add dev eth1 parent 1:0 protocol ip handle 4 fw flowid 1:40
tc filter add dev eth1 protocol ip parent 1:0 handle 80 fw flowid 1:80

Here's my iptables:

-A PREROUTING -p tcp -m tcp --sport 3128 -j MARK --set-mark 0x2
-A PREROUTING -p tcp -m tcp --dport http -j MARK --set-mark 0x2
-A PREROUTING -p tcp -m tcp --dport https -j MARK --set-mark 0x2
-A PREROUTING -p tcp -m tcp --dport 53 -j MARK --set-mark 0x1

-A PREROUTING -p tcp -m multiport --dports 110,25 -j MARK --set-mark 0x3
-A PREROUTING -p udp -m udp --dport 123 -j MARK --set-mark 0x4
-A PREROUTING -p udp -m udp --dport domain -j MARK --set-mark 0x1
-A OUTPUT -p tcp -m tcp --sport 3128 --destination 192.168.1.145 -j MARK --set-mark 0x4

here's the output of iptables -L -v -x -t mangle

notice the class htb 1:40 doesn't have packet lended.

Please help me , and pardon my english.
has anyone experience this?
