XBOX and setting NAT to OPEN with a Linkseys E1000

Question

And before someone posts it, I have used this guide as well as dozens of others.
http://www.xbox360forum.com/xbox-forum/threads/51908-How-To-Open-NAT.-xbox-360.
I really don't know what to do. No matter what I do, I just can't get it to go from Moderate to Open. I'm honestly thinking about returning the router and going with a new brand. I have followed multiple guides and nothing works.
