How to Fix PS4 NAT Error NAT Type Failed on Windows 11: Complete Troubleshooting Steps

Experiencing a NAT Type Failed error on your PS4 while using Windows 11 can be frustrating. This issue often affects your ability to connect to online games and chat with friends. Fortunately, there are several straightforward steps you can take to resolve this problem.

This guide will walk you through easy-to-understand troubleshooting methods. Each step is designed for users with any level of technical knowledge. By following these instructions, you should be able to fix the NAT error and improve your PS4’s online experience.

Before diving into the fixes, it’s important to understand that NAT (Network Address Translation) controls how your console connects to other players and servers. A failed NAT type means your connection is being blocked or limited.

Let’s begin with some quick checks and prerequisites to save time and ensure you don’t miss anything simple.

Quick Note: Prerequisites and Initial Checks

  • Check your internet connection: Make sure your Windows 11 PC and PS4 have stable internet access.
  • Confirm your PS4 is connected to the same network: Both devices should be on the same Wi-Fi or wired network.
  • Restart your devices: Power cycle your router, Windows 11 PC, and PS4. Sometimes, this alone resolves connection issues.
  • Disable VPN or proxy: If you use any VPN or proxy on Windows 11, disable it temporarily to avoid interference.

Step 1: Verify Your PS4’s Network Settings

Before making any changes on Windows 11, check your PS4’s network status to understand the current NAT type.

  1. On your PS4, go to Settings > Network > View Connection Status.
  2. Look for the NAT Type information. It will show Type 1, 2, or 3, or it might say “Failed.”

Why this matters: NAT Type 1 means an open connection, Type 2 is moderate, and Type 3 is strict. Type 3 or Failed NAT often causes problems with online gameplay.

Step 2: Set Up a Static IP Address for Your PS4

Assigning a static IP to your PS4 ensures it always uses the same local IP address. This is important for forwarding ports later.

  1. On your PS4, go to Settings > Network > Set Up Internet Connection.
  2. Choose your connection type: Wi-Fi or LAN cable.
  3. Select Custom setup.
  4. For IP Address Settings, select Manual.
  5. Enter an IP address within your router’s range (e.g., 192.168.1.100). To find your router’s range, check your PC’s IP by running ipconfig in Command Prompt.
  6. Set Subnet Mask to 255.255.255.0.
  7. Set Default Gateway as your router’s IP (usually something like 192.168.1.1).
  8. For DNS settings, use 8.8.8.8 and 8.8.4.4 (Google DNS) or your ISP’s DNS.
  9. Complete the setup and test the internet connection.

Why this helps: A static IP ensures your router can forward the proper ports to your PS4 without confusion caused by changing IP addresses.

Step 3: Enable UPnP on Your Router

Universal Plug and Play (UPnP) allows devices to configure port forwarding automatically, which helps with NAT issues.

  1. Open a web browser on your Windows 11 PC.
  2. Enter your router’s IP address in the address bar (commonly 192.168.1.1 or 192.168.0.1).
  3. Log in using your router’s username and password (check your router or ISP documentation if unknown).
  4. Find the UPnP setting in the router’s menu. This is often under sections like “Advanced,” “Network Settings,” or “NAT Forwarding.”
  5. Enable UPnP and save the settings.
  6. Restart your router and PS4, then test the connection again.

Why enable UPnP: This helps your router automatically open the right ports for your PS4, improving connectivity without manual configuration.

Step 4: Manually Forward PS4 Ports on Your Router

If UPnP is unavailable or doesn’t solve the problem, you can manually forward ports required by PS4 services.

  • TCP ports: 80, 443, 1935, 3478-3480
  • UDP ports: 3478-3479
  1. Access your router’s web interface again.
  2. Find the Port Forwarding or Virtual Server section.
  3. Create new port forwarding rules for each port (or port range) listed above, assigning them to your PS4’s static IP address.
  4. Set the protocol to TCP, UDP, or both as appropriate.
  5. Save the changes and restart your router and PS4.
  6. Test your PS4’s network connection.

Why port forwarding matters: It opens specific communication channels on your router, allowing your PS4 to connect freely to PlayStation network servers.

Step 5: Use DMZ as a Last Resort

If you still face NAT errors, placing your PS4 in the DMZ (Demilitarized Zone) of your router can help. This exposes the console directly to the internet without firewall restrictions.

  1. Log in to your router’s interface.
  2. Locate the DMZ settings.
  3. Enter your PS4’s static IP address as the DMZ host.
  4. Save the settings and reboot your router and PS4.

Important: Using DMZ removes some security protections, so only use this if other methods fail.

Alternative Method: Use Windows 11 Internet Connection Sharing

If your Windows 11 PC connects to the internet via Ethernet and your PS4 uses Wi-Fi, sharing the internet connection through your PC might help bypass NAT issues.

  1. Connect your Windows 11 PC to the internet via Ethernet.
  2. Go to Settings > Network & Internet > Mobile hotspot.
  3. Turn on Share my internet connection with other devices.
  4. Configure the network name and password.
  5. Connect your PS4 to this new Wi-Fi network.
  6. Test the connection and NAT type on your PS4.

FAQs

What is NAT and why does it matter on PS4?

NAT stands for Network Address Translation. It determines how your console communicates with other players and servers. A strict or failed NAT can block connections, causing lag or inability to join games.

Can I fix NAT errors without touching my router?

Sometimes restarting devices or setting a static IP on PS4 helps, but usually, router settings like UPnP or port forwarding are necessary for a permanent fix.

Is it safe to enable DMZ on my router?

DMZ exposes your PS4 directly to the internet, bypassing firewall protections. It can fix NAT issues but may increase security risks. Use it only if other methods fail.

Why does my NAT type keep changing?

If your PS4 receives a dynamic IP from the router, the port forwarding rules may not always apply. Setting a static IP fixes this problem.

Can Windows 11 firewall cause NAT errors?

Typically, your router handles NAT, but if you use your PC as a hotspot or for sharing, firewall settings on Windows 11 might interfere. Ensure relevant ports are allowed if sharing connections.

When Nothing Works

If you have tried all the above steps and still face NAT Type Failed errors on your PS4, consider the following:

  • Contact your Internet Service Provider (ISP) to check if they block certain ports or have additional firewall settings.
  • Check for router firmware updates from the manufacturer’s website and apply them.
  • Reset your router to factory settings and reconfigure it from scratch.
  • Visit the official PlayStation Support page for detailed advice: https://www.playstation.com/support/network/connectivity-issues/

Conclusion

Fixing the PS4 NAT Type Failed error on Windows 11 involves a series of simple steps, starting from verifying your network setup to adjusting router configurations. Setting a static IP, enabling UPnP, and forwarding ports are the most effective methods. Use DMZ carefully if needed, and explore alternative connection methods if necessary.

By following this guide, you can enjoy smoother online gaming experiences with fewer connection problems. Remember to perform each step patiently, and always restart devices after changes to apply new settings.
