Hi, This router has worked fine but I want to play on-line using my Xbox One but i recieve an error message when trying to connect to others.  I know that I have a diuble nat and assume that the double nat is the issue.

I have read some other threads but I havent been able to redolve the problem.  I have created a new profile and the UPnP is enabled. I trided to enable DMZ but it appears I have to entnter a DMZ Host IP address but I don't know what that is.  

Also I have read that I need to make sure my router has a public ip address and not a private one.  But I have no idea what a public IP address is?

Can anyone offer some help please. Many thanks.
