[LARTC] limiting upload speeds does not work

[Tomáš Hnyk]

Hello, I want only a very simple thing, but I have been unable to get it working so far. I would like to shape my DC++ traffic firmly to certain speeds. I am using an embedded linux router (asus wl500g), and a NATed PC (address 192.168.1.100). eth1 is a WAN interface and br0 is the LAN interface of the router.DC++ client is running on 4111 ports(tcp and udp) I actually managed to shape download wth this script:
iptables -t mangle -A FORWARD -p tcp --dport 4111 -j MARK --set-mark 1
tc qdisc add dev br0 root handle 1:0 htb default 0
tc class add dev br0 parent 1:0 classid 1:1 htb rate 1024kbit
tc class add dev br0 parent 1:1 classid 1:11 htb rate 256kbit
tc filter add dev br0 parent 1:0 protocol ip handle 1 fw flowid 1:11
And I thought it would be similar with upload, but it is not, I tried this script:
iptables -t mangle -A FORWARD -p tcp --sport 4111 -j MARK --set-mark 2
tc qdisc add dev eth1 root handle 2:0 htb default 0
tc class add dev eth1 parent 2:0 classid 2:1 htb rate 1024kbit
tc class add dev eth1 parent 2:1 classid 2:11 htb rate 256kbit
tc filter add dev eth1 parent 2:0 protocol ip handle 2 fw flowid 2:11
but it did not work. However, the problem seems to be in the way how I mark packets since when I type this:
iptables -t mangle -A FORWARD -i br0 -j MARK --set-mark 2
or this:
iptables -t mangle -A FORWARD -s 192.168.1.100 -j MARK --set-mark 2
upload immidiately goes to 64kbits or something, but so does everything else too - which is not exactly what I am trying to accomplish;-).
Since I am running out of ideas, have you got any? Or even an completely different approach to the problem? 
Thanks in advance,
Tomas
