This article is designed to resolve a "NAT Type Strict" or similar message on a Gaming Console (Xbox One, Playstation 4, Wii U, etc.) when trying to communicate with online services.
Configuration Difficulty: Beginner
- Step 1: Log into the router's NCOS page. For help with logging in please click here.
Step 2: Click on the Security tab in the navigational pane.
Step 3: Select Zone Firewall.
Step 4: Choose Options from the Zone Firewall drop-down.
Step 5: Scroll down to the DMZ (Demilitarized Zone) section.
Step 6: Check the box next to Enable.
Step 7: Input the IP address of your console into the IP Address field, then click Save.
- Note: If your console is obtaining an IP address automatically, via DHCP, you may need to create a DHCP Reservation for it in addition to adding it to the DMZ.
- Note: The IP address of your console can be found within its Network Configuration settings, or within the Cradlepoint admin console, under Status>Client List.
After these settings are submitted, your gaming console will be outside of the Cradlepoint router's firewall, which resolves any local NAT issues. If you continue you to receive the "Strict NAT" messages generated on the gaming console it is likely that your internet provider has a firewall in use on your connection. Further troubleshooting will need to involve the ISP.
