Strict NAT, I've tried everything

[TheZephyrBlade]

Hi Friends,

 

Really struggling with NAT type in my home network for my PS4.

I know this is a question asked a million times but no forum or site has helped me so far.

I've tried the usual troubleshooting and nothing is working, I'm out of ideas.

UPNP is enabled.

I've given the PS4 a static IP and opened the appropriate ports for it.

I've put the PS4 into the DMZ, still NAT Type 3. 

 

I currently have 2 networks going because of the size of the house. I have a NetComm NF18ACV Modem/Router running a network and a Netgear Nighthawk XR500 connected via ethernet and broadcasting a separate network simply because I'm unsure how to get them to work as one network. As such both are being used as a DHCP server and I'm not sure if this is a conflict.

That said, as a troubleshooting step I have powered off XR500 and connected the PS4 directly to the modem with the PS4 in the DMZ and still get NAT Type 3.

 

Does anyone have any idea what I could do next, my ISP was less than helpful, are there any other settings I can look at?

 

Thanks in advance

To get NAT type open on Modern Warfare for my PC I had to do all of this:

- Turn off the firewall of the modem/router from the ISP

- open ports for the game and the second router on the ISP router

- turn off upnp on the ISP router

- add the second router as DMZ

- turn the firewall off of the second router (asus)

- open the ports for the game for the PC-s IP address on the second router

- turn off upnp on the second router

- add the PC to the DMZ on the second router

- turn off the Win firewall, reset the firewall settings and turn it back on

- multiple restarts of the routers, especially the ISP one, in order for the settings to register

Having ports open and DMZ makes no sense since DMZ should mean all ports are open, but in my case it had to be done in order to work.

If the second router is in router mode, which it sounds like. You have TWO LAYERS of NAT going. This is your issue. Hooking a router to a router is never a good solution becuase of double NAT. You either have put the second router in AP mode, OR port forward on your modem/router as well and hope it works.

This! Having two wireless networks is fine, but you never want two different subnets in your house. If your modem is acting like a router, then you need to disable the routing services on the other router (either set it to AP mode, if it doesn't have that, then disable DHCP, set the LAN IP address to something on your network, perhaps 192.168.1.2 and then connect it VIA a LAN port, not the WAN port).

 

The other option is to change the modem to bridge mode so that your own router can function as a router, but doing that will also disable its WiFi, which you may not want to do.
