PS4 NAT Type Failed is a voice chat problem on PlayStation 4 that often occurs during group chats and games. When the problem occurs, the console displays a NAT type error message.

NAT stands for Network Address Translation, which translates public IP addresses into private IP addresses. A NAT type error can be corrected by configuring the network settings to change the NAT type.

This article on IR Cache presents effective methods to resolve PS4 NAT type failure. Try the following methods.

What Causes a PS4 NAT Type Failed Problem

PS4 NAT type Failed is usually triggered by incorrect network settings, or the problem occurs because of the network firewall. Changing the NAT type is one of the effective solutions to resolve this behavior.

Sometimes PS4 NAT errors may be caused by incorrect network settings saved on the console. You should check the IP address of your PS4 and make sure that it is assigned correctly or that it has been changed correctly.

In some cases, the problem may be caused by your router using the IPV6 connection type to connect the PS4 to its servers, and this can usually be solved by changing it in the router settings, but you will need a computer to broadcast these changes correctly.

How to Resolve the PS4 NAT Type Failure



Turn on Universal Plug and Play (UPnP) on the router

You can enable Universal Plug and Play (UPnP) for your router, which allows network devices to discover each other over the Internet and set up functional network services.

So, if you encounter a “PS4 NAT Type Failed” problem and can’t communicate with other people over the network while playing, you can do the following steps to enable UPnP.

1. Check the IP address, user name, and password on the back of the wireless router.
2. Open the browser on your PC, enter the IP address in the browser, and press Enter.
3. Enter your user name and password, then press Enter.
4. Find the UPnP menu and enable the UPnP service.
5. Save your changes, then restart the router.
6. Then go to PS4 Settings -> Network -> Check Internet Connection and see if the PS4 NAT failed error is gone.

Make your PS4 a DMZ server

DMZ stands for “demilitarized zone.” It is a physical or logical subnet that contains an organization’s outgoing services to an untrusted network.

It can help you fix router network configurations and improve network performance if the settings are checked correctly. (Some people may be concerned that this method will cause security problems, but that’s not a problem since you’re using the network at home and not in public places.)

1. Look up the IP address, username, and password of your wireless router.
2. Open the browser on your computer or cell phone, enter the IP address in your browser, and press enter.
3. Enter your user name and password and log in.
4. Go to Advanced -> Forwarding and you will see the DMZ section on the left (or you may find the DMZ section in another tab, depending on different routers).
5. Click Enable to activate the DMZ.
6. Change the IP address to match the IP address of your PS4.
7. If you are using routers with the NAT filtering option, such as NETGEAR routers, you can also click to open NAT filtering. (You can skip to the next step if you do not have this option).
8. Click Apply/Save to save your settings.
9. Restart the router and wait for it to connect.
10. Go to PS4 Settings -> Network -> Check Internet Connection and make sure the NAT type is enabled (you will see Type 1 or Type 2 if it works).

Manually configuring PS4 network settings

Incorrect network settings can cause a PS4 NAT Type Failed error. So check if the IP address of your PS4 has changed. If it has, you can manually adjust the network settings to fix it in your PS4.

1. Prepare a computer or laptop that uses the same network as your PS4.
2. On your computer, type cmd in the Windows search bar and click on the most appropriate command line to open it.
3. Type the following command in the command prompt window and press Enter: ipconfig/all.
4. Note the IP address, default gateway, subnet mask, and DNS server.
5. On the PS4, go to Settings -> Network -> Configure Internet Connection.
6. Select Use WiFi if you are connecting the PS4 to the Internet via WiFi, or select Use LAN cable if you are using Ethernet.
7. Then select Custom to manually add network information.
8. Select Do not use for proxy server.
9. When you see that your Internet settings are updated, select Check Internet Connection.
10. After that, you will be able to see the NAT Type and the PS4 NAT Type Failed error should be fixed.
