can != want != will

You may have a problem with the rate units -  bps != bit -, but i dont know the
type or rate of your internet link.
Post a detailed ascii diagram of your network. Which is the transfer rate of the
internet link?

IPP2P works very well for me.
How did you test your iptables & tc setup? In the real network or in a
controlled environment?
Did you try starting with a very basic tc setup and adding tc qdiscs, classes
and filters one by one and checking the results on every step?

Regards,
Francisco.
