I keep getting a Strict NAT on xbox live even though it is connected directly to my modem. How do i fix this?


I’m trying to get an open NAT on Xbox live. It says it is strict I run my xbox directly to my modem, so in theory there should be no problem, but there is any help would be much appreciated.

  1. Are you sure thats a modem? Or is it a gateway device that acts as a modem and a router at the same time? If it’s a gateway device, then you will want to follow these steps to obtain open nat:

    1) Make sure the xbox will always be assigned the same IP address, you can do this by reserving an IP address in the DHCP reservation area of your gateways firmware, or by entering the IP, Subnet, and Default gateway into the console.

    2)The easiest way to make sure you have the proper ports for the console is to assign the consoles IP address as the DMZ host.


    If it is a modem only then that means your ISP is doing routing on the back end of their network, and you will need to call them and ask about obtaining a static IP address for your modem
    I highly suggest you call xbox netwrking support for assistance in obtaining open NAT.
