Hello, I am trying to open my NAT on Xbox 360. I am using a Linksys E3000 and am directly connecting my Xbox to my laptop. I have previously received an Open NAT on this system with this router before (albeit with an automatic IP address), so I know my hardware is capable of managing multiple IPs.
The Xbox automatically assigns 192.168.0.xxx for my IP address, and automatically assigns 192.168.0.1 for my gateway. However, the number I type in to access my router administration (and the gateway address listed under my laptop's ipconfig in the command panel) is 192.168.1.1, and the Port Range Forwarding IP addresses/ DMZ destinations on my router requires the first three parts of the IP Address to be 192.168.1.xxx. If both of the numbers are 0, then my Xbox connects to the Internet, but has a moderate NAT; if I change any of those numbers to 1, I cannot connect to the network whatsoever.
I am careful to choose an IP which is not inside my DHCP range, if that makes a difference. I have already entered the ports to forward on my network admin and have enabled DMZ. I am certain the problem lies with the static IP address, and am utterly confused why my Xbox wants to connect to a different gateway than what my computer uses. Any help would be greatly appreciated.
