bandwitdh is not limited

[Yudi]

I'm student who's doing final project about QoS in ipv6,
Finally, I can use dummynet by changing FREEBSDv4.9 to FREEBSDv5.3 for limiting my local bandwitdh.
But, i'm confused that the bandwitdh is not limited. I know that by using ethereal and some streaming video.
the sintag is oke , here it is :
 
# ipfw add pipe 1 ipv6 from any to any
# ipfw pipe 1 config bw 10kbit/s
# ipfw show
00100 0 0   pipe 1 ipv6 from any to any
65535 0 0   allow ip from any to any
 
Can anyone figure it out ???
Thanks before
