Ok so i recnetly change modems and then I switched them back but now on COD AW its showing STRICT/MODERATE Nat Type
Is there anyway I can get this to NAT TYPE: OPEN

Hello,

I may be going over things you already know, if so I apologise in advance...

NAT stands for Network Address Translation which is the way your router controls the local 192.168.X.X address of your Xbox and broadcasts all of your packets over the internet using the address assigned to your router/modem. Which means that the setting is going to be in your modem/router configuration. With that said, here is a link to a site that discusses the issues and solutions for the issues that you are having and specifically addresses the Xbox:
