Upload problem with traffic shaping though a Linux router.

So I want to limit the download and upload speed of a specific ip adress in a local network. To do this I are using a bach script running in a linux OS (Ubuntu 11.04). The issue here is that the upload shaper does not work. I have tried an alternate solution aswell though that does not work as intended

# Remove old shaping
tc qdisc del dev eth1 root 2> /dev/null > /dev/null
tc qdisc del dev eth1 ingress 2> /dev/null > /dev/null

# Create qdisc
tc qdisc add dev eth1 root handle 1: htb default 30

# Download shaper (works as intended)
tc class add dev eth1 parent 1:1 classid 1:4 htb rate 30000kbt
tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip dst 192.168.0.101/32 flowid 1:4

# Upload shaper (does not seam to do anything)
tc class add dev eth1 parent 1:1 classid 1:3 htb rate 3000kbit
tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip src 192.168.0.101/32 flowid 1:3

### Version 2 of the upload shaper:
# Need eth0 aswell to do this
tc qdisc add dev eth0 root handle 1: htb default 30

# Upload shaper (limits the entire network and not just the one IP)
# The reason for 192.168.0.101/0 is because the src is 10.0.0.166. 10.0.0.166 is the WAN IP adress. I dont get why this is.
# I dont know why i need to change it to eth0 either. It does nothing if i dont.
tc class add dev eth0 parent 1:1 classid 1:3 htb rate 3000kbit
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip src 192.168.0.101/0 flowid 1:3

Any help at all would be MUCH appreciated!

Match-all classifier in tc(8)                                          Linux                                         Match-all classifier in tc(8)

NAME

       matchall - traffic control filter that matches every packet

SYNOPSIS

       tc filter ... matchall [ skip_sw | skip_hw  ] [ action ACTION_SPEC ] [ classid CLASSID ]

DESCRIPTION

       The matchall filter allows to classify every packet that flows on the port and run a action on it.

OPTIONS

       action ACTION_SPEC
              Apply an action from the generic actions framework on matching packets.

       classid CLASSID
              Push matching packets into the class identified by CLASSID.

       skip_sw
              Do  not  process filter by software. If hardware has no offload support for this filter, or TC offload is not enabled for the inter-
              face, operation will fail.

       skip_hw
              Do not process filter by hardware.

EXAMPLES

       To create ingress mirroring from port eth1 to port eth2:

              tc qdisc  add dev eth1 handle ffff: ingress
              tc filter add dev eth1 parent ffff:           
                      matchall skip_sw                      
                      action mirred egress mirror           
                      dev eth2

       The first command creats an ingress qdisc with handle ffff: on device eth1 where the second command attaches a matchall filters on it  that
       mirrors the packets to device eth2.

       To create egress mirroring from port eth1 to port eth2:

              tc qdisc add dev eth1 handle 1: root prio
              tc filter add dev eth1 parent 1:               
                      matchall skip_sw                       
                      action mirred egress mirror            
                      dev eth2

       The  first  command  creats  an egress qdisc with handle 1: that replaces the root qdisc on device eth1 where the second command attaches a
       matchall filters on it that mirrors the packets to device eth2.

       To sample one of every 100 packets flowing into interface eth0 to psample group 12:

              tc qdisc add dev eth0 handle ffff: ingress
              tc filter add dev eth0 parent ffff: matchall 
                   action sample rate 100 group 12
