Microwave internet.

I have an internet connection via microwavelengths. I am able to get on psn and play mw2, borderlands, etc. But my nat type is strict for mw2, and i wanted to know if i can fix this. There is a dish thing on my house with an ethernet running to my computer. This ethernet then has a black box conected to it with an ethernet cable on the other side. Dish-ethernet-black box-ethernet-computer. I use this same connection to get on psn with my ps3. I don't think there is any router involved, but any input would be greatly appreciated. (In changing my NAT to open or moderate, that is) -also, no router=no port forwarding.

That's what i was thinking. But it's like an inch wide. I assume its some form of router or something, but it has no wireless. so im stumped
