Limiting BT (p2p) speeds [iptables]

[Vict0r]

OK.
I've looked on google how to limit bittorrent speeds using iptables but I found nothing.

So since this is a networking forum I assume *someone* should know how to do this.

Here is what I need.
I need a iptable script that I can input in my DD-WRT WRT54GL Linksys router.

This iptable should limit download speed to 200kbp/s MAX download speed and 25kbp/s MAX upload speed while using bittorrent. I will limit it on a specific MAC adress. But first make a table and put like "<mac-address-goes-here>" and I will edit script and input the MAC

Thank you in advance guys ! I hope you can help me
