I had to change peergaurdian2 to allow the utorrent site to be allowed. It was blocking their site and for some reason screwing my download and upload speeds.
If you want use utorrent and peergaurdian2 (you should use PG2), then use the port testing function and grab the website address and make sure to allow it in PG2.
BTW, I agree that port forwarding is a must! Here is a site that will give a really good description for a variety of routers.
