How to Change NAT Type on PC Windows 11: A Step-by-Step Guide

By / September 27, 2025

If you’re a gamer or someone who frequently uses online apps, you’ve probably faced network issues like lag, failed connections, or limited voice chat features. In many cases, the culprit is your NAT type. On Windows 11, having the wrong NAT type can cause frustration when connecting to online services.

In this step-by-step guide, we’ll explain what NAT is, why it matters, and how to change NAT type on PC Windows 11 using different methods. By the end, you’ll know how to switch from Strict or Moderate NAT to Open NAT for smoother online experiences.

Summary: Key Takeaways

  • NAT (Network Address Translation) controls how your PC communicates with the internet.

  • Windows 11 users often face Strict NAT issues, especially in gaming.

  • NAT types: Open (best), Moderate (okay), Strict (worst).

  • You can change NAT type on Windows 11 by:

    • Enabling UPnP in your router

    • Using Port Forwarding

    • Configuring Windows Firewall

    • Using a VPN

    • Turning on Network Discovery

  • Always restart your router and PC after making changes.

What Is NAT and Why Does It Matter?

NAT (Network Address Translation) acts like a traffic controller for your internet connection.

Imagine you live in an apartment building (your router), and each person in the building (devices like PC, phone, console) has a room number (local IP address). NAT is the receptionist who ensures data reaches the right room and manages outside visitors.

Why does NAT matter for gaming and online apps?

  • Open NAT = Easy connections with everyone, smooth online play.

  • Moderate NAT = Some restrictions, but generally playable.

  • Strict NAT = Limited connections, longer matchmaking times, voice chat issues.

How to Check NAT Type on Windows 11

Before changing it, you need to check your current NAT type:

  1. Press Windows + I to open Settings.

  2. Go to Gaming > Xbox Networking (yes, even on PC).

  3. Windows will test your connection and show the NAT type:

    • Open

    • Moderate

    • Strict

If you see Strict or Moderate, you’ll want to change it.

Methods to Change NAT Type on PC Windows 11

There are several methods you can try, from simple settings to router configurations.

1. Enable UPnP (Universal Plug and Play) in Your Router

UPnP automatically configures your router to allow applications to connect freely.

Steps:

  1. Open your web browser and type your router’s IP address (usually 192.168.1.1 or 192.168.0.1).

  2. Log in with your router credentials.

  3. Look for Advanced Settings > NAT Forwarding > UPnP.

  4. Enable UPnP.

  5. Save changes and restart your router.

✅ This often changes NAT type to Open instantly.

2. Use Port Forwarding

Some games and apps require specific ports to be open.

Steps:

  1. Find your PC’s IP address:

    • Press Windows + R, type cmd, and run ipconfig.

    • Note down your IPv4 Address.

  2. Log into your router’s admin panel.

  3. Go to Port Forwarding / Virtual Server settings.

  4. Add rules for required ports. Example (Xbox Live services):

    • TCP: 53, 80, 3074

    • UDP: 53, 88, 500, 3074, 3544, 4500

  5. Save and restart your router.

✅ Best for gamers who want permanent Open NAT.

3. Allow Ports in Windows Firewall

Sometimes the Windows Firewall blocks the necessary ports.

Steps:

  1. Press Windows + S, search for Windows Defender Firewall, and open it.

  2. Click Advanced settings.

  3. Select Inbound Rules > New Rule.

  4. Choose Port, then TCP/UDP, and enter required port numbers.

  5. Allow the connection and give it a name.

  6. Repeat for Outbound Rules.

✅ This ensures your firewall isn’t blocking connections.

4. Turn On Network Discovery

Enabling Network Discovery makes your PC more visible on the network.

Steps:

  1. Open Control Panel > Network and Sharing Center.

  2. Click Change advanced sharing settings.

  3. Turn on Network Discovery and File & Printer Sharing.

  4. Restart your PC.

This doesn’t always fix NAT issues but can help with peer-to-peer connections.

5. Use a VPN Service

A VPN (Virtual Private Network) can bypass NAT restrictions if your ISP uses Carrier-Grade NAT (CGNAT).

Steps:

  1. Download and install a reliable VPN (e.g., NordVPN, ExpressVPN).

  2. Connect to a server close to your region.

  3. Launch your game or app again.

✅ A VPN may reduce ping slightly but helps if your ISP enforces Strict NAT.

6. Set a Static IP Address

If your PC’s IP changes frequently, your router may not forward ports correctly.

Steps:

  1. Open Control Panel > Network and Sharing Center.

  2. Click your active network > Properties.

  3. Double-click Internet Protocol Version 4 (TCP/IPv4).

  4. Select Use the following IP address.

  5. Enter a static IP (within your router’s range).

Now configure port forwarding for this static IP.

Troubleshooting NAT Issues on Windows 11

If NAT still won’t change, try these fixes:

  • Restart router and PC after changes.

  • Update router firmware to latest version.

  • Check for double NAT (if you’re using two routers or modem + router setup).

  • Reset Windows Firewall to default settings.

  • Contact ISP if your NAT remains Strict (they may use CGNAT).

Comparison of NAT Types

Here’s a quick breakdown of NAT types:

NAT Type Connectivity Best For Limitations
Open Connects with all Gaming, streaming, voice chat None
Moderate Connects with Open & Moderate Casual use May cause slow matchmaking
Strict Limited connections Rare cases High ping, failed connections

Pro Tips for Gamers

  • Always use a wired Ethernet connection for the lowest latency.

  • If multiple PCs/consoles are on the same network, one device may get Open NAT while others get Moderate/Strict.

  • Use port forwarding with static IP for the most stable Open NAT.

Conclusion

Changing your NAT type on PC Windows 11 can dramatically improve your online gaming, streaming, and communication experience. Whether you enable UPnP, configure port forwarding, or use a VPN, there’s a solution for every user.

If you’re serious about gaming, aim for an Open NAT—it gives you the best possible connection with fewer restrictions.

FAQs

1. How do I fix Strict NAT type on Windows 11?

Enable UPnP on your router or use port forwarding to open required ports.

2. Does VPN change NAT type on PC?

Yes, a VPN can bypass Strict NAT if your ISP uses Carrier-Grade NAT (CGNAT).

3. Can I change NAT type without accessing my router?

Yes, you can try using a VPN or enabling Network Discovery, but the best method is router configuration.

4. Will changing NAT type improve my ping?

Not directly. NAT type affects connectivity, while ping depends on network speed and distance to servers.

5. Is it safe to enable UPnP on my router?

Generally yes, but it can expose your network if not secured. For better safety, use manual port forwarding.
