|It seems by the make / model of your router you don't need to configure a static ip address as the router defines your connection by identifying your pc.|
I was going to refer you to the page pibelman has linked you to.
When you start a torrent download click on peers in the bottom left of the bitcomet window. Do you get connections that show both remote and local? If you do that means that the port forwarding is working. I've noticed sometimes bitcomet will give the orange light when it is working fine.
If it is any consolation I've never noticed a significant speed increase with port forwarding, although I use bitcomet to download the latest linux distros, so there are always plenty of seeds anyway.
