NAT, or Network Address Translation, is a set of procedures used to translate private IP addresses within a network into a single public IP address. This translation allows multiple devices within the network to access the internet using a shared IP address. NAT serves as a temporary solution to the limited availability of IPv4 addresses until the widespread adoption of IPv6.

What is NAT?

NAT, or Network Address Translation, is a fundamental aspect of network management that involves translating private IP addresses used within a local network into a single public IP address. This translation process enables devices in the network to communicate with devices outside the network, such as servers on the internet. NAT acts as a bridge between the private network and the public internet, ensuring smooth data transmission and connectivity.

How to change the NAT type on a PC: 5 methods

There are several methods you can use to change your NAT type on a PC. Each method offers different options and levels of control. Here are five commonly used methods:

Method #1: Turn on UPnP on the router

UPnP (Universal Plug and Play) is a protocol that allows devices on a network to automatically configure port forwarding, simplifying the process of opening ports for applications like gaming. Enabling UPnP on your router can help achieve a more open NAT type. Follow these steps to turn on UPnP:

1. Find your router’s IP address by following the instructions mentioned earlier.
2. Enter the router’s IP address into your preferred web browser.
3. Access your router’s advanced settings.
4. Locate the option to enable UPnP and check the corresponding box or button.

Remember to save the changes after enabling UPnP. Note that enabling UPnP may pose some security risks, so it’s essential to keep your router’s firmware up to date and regularly monitor your network for any suspicious activity.

Method #2: Port forwarding

Port forwarding allows you to manually open specific ports on your router to direct incoming traffic to a particular device or application. By forwarding the required ports for gaming, you can achieve a more open NAT type. Follow these general steps to set up port forwarding:

1. Determine the ports needed for your game or application. This information is often available on the creator’s website or through online sources.
2. Access your router’s configuration page using the steps mentioned earlier.
3. Locate the port forwarding settings in the advanced settings section.
4. Enable port forwarding and enter the necessary details, such as the port numbers and the device’s IP address.
5. Save the changes to apply the port forwarding configuration.

Depending on your router model and internet service provider, your router may have predefined ports available for popular games or applications. These predefined ports can simplify the port forwarding process.

Method #3: Turn on Network Discovery on Windows 10

Network Discovery is a feature in Windows 10 that enables devices on a local network to easily find and communicate with each other. Enabling Network Discovery can help achieve a more open NAT type on Windows 10. Follow these steps to turn on Network Discovery:

1. Open the Windows Control Panel.
2. Click on “Network and Internet” and navigate to the “Network and Sharing Center.”
3. Click on “Change Advanced Sharing Settings.”
4. Find the “Network Discovery” subheading and select the option to turn it on.

Ensure that you activate Network Discovery only within your local area network to maintain security.

Method #4: Edit the configuration file

Editing the configuration file of your router allows you to make specific changes to its settings. This method requires caution and should only be performed if you have a good understanding of your router’s configuration. Here are the general steps to edit the configuration file:

1. Open the configuration file using a text editor like Notepad.
2. Use the search function (usually activated with Ctrl+F) to find the “last bind” section.
3. Type “bind application=CONE(UPD) port=XXXX-XXXX” in the configuration file, replacing the X’s with the desired port number.
4. Save the changes to the configuration file.
5. Access your router’s settings and search for the option to load or restore the configuration file.
6. Select the edited configuration file and apply the changes.
7. Restart your PC for the changes to take effect.

Note that editing the configuration file requires caution, and any changes should be made after creating a backup to ensure you can revert to the previous configuration if needed.

Method #5: Enable DMZ mode

DMZ (Demilitarized Zone) mode is a feature available in some routers that exposes a single device on the network directly to the internet. Enabling DMZ mode can result in a more open NAT type, but it comes with security implications. Use this method only as a last resort and for temporary purposes. Here’s how to enable DMZ mode:

1. Access your router’s configuration page using the steps mentioned earlier.
2. Navigate to the advanced settings section.
3. Find the DMZ mode option and enter the static IP address of the device you want to expose to the internet (use the same IP address from your IP config readout).

It’s important to note that enabling DMZ mode exposes the selected device to potential security risks. It is recommended to use port forwarding or UPnP instead for long-term solutions.

By following these methods, you can manage and optimize your NAT type for a seamless online gaming experience across various platforms, operating systems, and devices. Remember to consult the specific documentation or support channels provided by the platform or device manufacturer for detailed instructions tailored to your setup.

NAT type connectivity issues

While NAT offers benefits for managing network traffic and providing internet connectivity, it can also lead to connectivity issues in certain scenarios. Here are some common NAT type connectivity issues:
