If your EXTERNAL IP (Like 89.43.94.272) is Dynamic, you have No problem. You need your LOCAL IP (Like 192.168.0.3) to be static (Not always, mind you), then you shouldn't have any problems.

Find out the IP address for your computer (the LOCAL network address), then use that IP when you are port-forwarding on your router.
