Strict NAT, all attempts made
Strict NAT, all attempts made
Hey there, friends. I see you're facing some challenges with your PS4's NAT settings. It sounds like you've already tried many common fixes, but still stuck. UPNP is active, static IP assigned, ports opened, and you've even tried placing the device in DMZ. You're juggling two networks due to your home layout, and both are acting as DHCP servers, which might be causing confusion. I'm not sure if powering off the XR500 and connecting the PS4 directly to the modem resolves the issue, but it’s worth testing. Have you checked the router's DHCP settings or considered switching to a different IP range? Let me know if you want more specific steps!
To enable NAT type open on Modern Warfare for my PC, I had to follow these steps: disable the firewall on the modem/router provided by the ISP, enable specific ports for the game and the second router on the ISP setup, configure the second router as a DMZ, switch off the firewall on the ASUS router, allow game ports to be open for the PC’s IP address on the second router, turn off UPnP on both routers, add the PC to the DMZ on the second router, disable the Windows firewall, reset the firewall settings and restore them, and perform multiple reboots—especially of the ISP router—to ensure the changes take effect. Having ports open and using DMZ was necessary because it seemed contradictory, but it was required for the configuration to function.
If the second router operates in router mode, you're dealing with two NAT layers. This setup is likely the cause of your problem. Connecting a router to another router isn't recommended due to double NAT issues. Either switch the second router to AP mode or configure port forwarding on your modem/router, and see if that resolves the issue.
This approach works with two wireless networks, but avoid having separate subnets inside your home. If your modem behaves like a router, turn off its routing features—either switch it to AP mode (if unavailable), disable DHCP, assign a LAN IP like 192.168.1.2, and connect via a LAN port instead of WAN. Alternatively, switch the modem to bridge mode so your router handles routing, though this will also turn off its WiFi.
