No problem. You have to go to Control Panel => Network and sharing center => On the left click change adapter configuration => Select your network card, right click, properties (UAC will prompt here) => Select TCP/IPv4 and click properties.
Here you'll see the screen where you can change your local IP for that machine, select use this IP address and enter a number in the same range as your router and fill the other fields.
With that fixed address you can then, on the router, forward the uTorrent port to your PC to have full connectivity.
