I can't open NAT for my Xbox when it's connected to my laptop?

Hmm, is it possible?

I've tried a couple of things, but they never worked, any information would come in handy.

I have it set up something like this: Xbox-Ethernet cable-Laptop-Wireless-Router

Edit: I am connected to Xbox Live btw. Just the NAT won't open, so I can't connect to any games online :/
