Problem with router and utorrent

[Ultiweap]

Hi everyone,

I just get my new livebox(router) for my new internet connection. The problem is that I don't know how to configure it to open a port for that router for utorrent to be eligible to download well as everytime the utorrent status is red or yellow and never green as it should be.

I would to know if someone could help me for that as it is very annoying.

The router is a Sagem Fast 3202

Thanks in advance for the help
