What are the ways to change NAT type? (2024)

Like most people, you probably don’t think about your internet connection often. But did you know there are different types of connections, and each has benefits and drawbacks? This article will look at the NAT type, what it is, and what to consider when choosing your connection.

For example, a strict NAT type can cause issues when trying to play multiplayer games. This guide will walk you through the various methods for changing your NAT type. Learn how to configure your router and troubleshoot connection issues.

What Is NAT and What Is Its Purpose?

Network Address Translation (NAT) is a technology most commonly used by firewalls and routers to allow multiple devices on a LAN with ‘private’ IP addresses to share a single public IP address.

The primary purpose of NAT is to improve security by hiding the internal network structure and IP addresses from the outside world. NAT also has the added benefit of conserving limited public IP addresses.

However, NAT can cause problems with specific Internet applications requiring all users to have a public IP address. For example, NAT can prevent two-way voice communication (e.g., VoIP), gaming, or other real-time applications from working correctly.

What Are the NAT Types?

A NAT type is a configuration setting on a router that determines how the router handles incoming and outgoing traffic. There are three main NAT types:

• Open: This is an ideal NAT type as it allows your computer to connect to any other computer or network without restrictions.
• Moderate: This NAT type allows your computer to connect to most other computers and networks, but some restrictions may exist.
• Strict: This is the least ideal NAT type as it severely restricts your computer’s ability to connect to other computers and networks. In some cases, it may not be possible to connect at all.

Which NAT Type Is the Best?

The ideal NAT type is Open, allowing your computer to connect to any other computer or network without any restrictions. However, Moderate and Strict NAT types are also common and can often still provide good speeds and reliability.

If you have difficulty connecting to other computers or networks, try using a VPN, which can often bypass NAT-type restrictions.

Hopefully, this article has helped you to understand NAT types and how to change them. Now we will proceed to change the NAT Types.

How to Moderate NAT Type With a Router?

NAT can be a useful tool for moderating traffic on your network. It can also be used for security purposes, by hiding the real IP addresses of devices on your network. If you want to use NAT to moderate your traffic, you need to enable it on your router and create a mapping between the internal and external IP addresses.

However, to do it right, you must follow some rules. We will describe these rules in the next two blocks.

Check Your Router’s Documentation

Before making any changes to your router, it is always a good idea to check the documentation first. Many routers have a web-based interface that you can use to change the NAT type. Consult your router’s documentation for specific instructions on how to do this.

Change the router’s NAT settings

If your router does not have a web-based interface, or if you can’t find the appropriate settings, you may need to change the NAT settings directly on the router. Again, consult your router’s documentation for specific instructions on how to do this.

How to Change Nat Type on PC

Changing the NAT type on your computer may help resolve these issues. There are a few different ways to change the NAT type, which we will outline below:

• Use port forwarding: Port forwarding is a technique that can improve some applications’ connection speed and reliability. When you use port forwarding, you are essentially creating a rule that tells the router to send traffic from a specific port on your computer to a particular port on another. To use port forwarding, you need to know the computer’s IP address to which you want to forward traffic.
• Use a VPN: A Virtual Private Network (VPN) can be used to improve the connection speed and reliability of some applications. A VPN creates a secure, encrypted tunnel between your computer and another computer or network.
• Use UPnP: Universal Plug and Play is a technology that allows devices on a network to discover and configure themselves automatically. Many routers support UPnP, and it can be used to change the NAT type. To use UPnP, ensure it is enabled on your router.

How to Do It on Windows

It depends on the Windows version:

• Windows 7/8/10/11:
  1. Open the ‘Network and Sharing Center and click ‘Change adapter settings.
  2. Right-click on the network adapter you are using and select ‘Properties.’
  3. Click the ‘Advanced’ tab and select ‘Internet Connection Firewall.’
  4. Click ‘Settings’ and select the ‘UPnP’ tab.
  5. Check the ‘Enable UPnP’ box and click ‘OK.’
• Windows Vista:
  1. Open the ‘Control Panel and click ‘Network and Internet.
  2. Click ‘Network and Sharing Center and click ‘Manage network connections.
  3. Right-click on the network adapter you use and go to ‘Properties.’
  4. Click the ‘Advanced’ tab and select ‘Internet Connection Firewall.’
  5. Click ‘Settings’ and Select the ‘UPnP’ tab.
  6. Check the ‘Enable UPnP’ box and click ‘OK.’

As you can see, the Windows Vista instruction differs only in one paragraph.

How to Do It on Mac OS X

Open the System Preferences application and click ‘Network .’Select the network adapter you are using from the list on the left and click ‘Advanced .’Click the ‘TCP/IP’ tab and select ‘Using DHCP with manual address. Enter your router’s IP address in the ‘Router’ field and click ‘OK.’

How to Do It on Linux

Most Linux distributions come with a UPnP client called ‘MiniUPnPc.’ To install it, open a terminal and enter the following command (delete quotes when using these commands):

• ‘sudo apt-get install miniupnpc’

Once MiniUPnPc is installed, you can use it to change the NAT type. Open a terminal and enter the following commands:

• ‘sudo su’
• ‘echo 1 > /proc/sys/net/ipv4/ip_forward’
• ‘iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE’
• ‘miniupnpc -a $(ip addr show eth0 | grep “inet ” | cut -d’ ‘ -f6 | cut -d/ -f1)’

Replace ‘eth0’ with the name of your network adapter.

How to Change NAT Type With a VPN?

A VPN can be used to improve the connection speed and reliability of some applications by creating a secure, encrypted tunnel between your computer and another computer or network. This can often bypass NAT type restrictions and other types like content or links restrictions.

You must sign up for a VPN service and install the VPN software on your computer to use a VPN. Once you have done this, connect to a VPN server, and your traffic will be routed through the VPN tunnel.

Is It Secure to Modify Your Nat Type?

Yes, it is perfectly safe to modify your NAT type. NAT types are simply configuration settings on your router and have no bearing on the security of your network.

In fact, in some cases, modifying your NAT type can improve your network’s security as it can help prevent malicious traffic from reaching your computer.

Can I Change My Nat Type Permanently?

Yes, you can change your NAT type permanently by changing your router’s configuration. However, if you are using a VPN, you must keep the VPN software installed on your computer to maintain a secure, encrypted connection.

Do All Games Require an Open Nat Type?

No, not all games require an Open NAT type. However, some games may have difficulty connecting or run less smoothly if you have a Moderate or Strict NAT type.
If you have difficulty connecting to other players or your game is running slowly, try using a VPN, as this can often bypass NAT type restrictions.

Conclusion

NAT types are configuration settings on your router that determine how the router handles incoming and outgoing traffic. The ideal NAT type is Open, allowing your computer to connect to any other computer or network without restrictions.

However, Moderate and Strict NAT types are also common and can often still provide good speeds and reliability. Hopefully, this article has helped you to understand NAT types and how to change them.

And if you decide to use a VPN for changing NAT type, you should find the best VPN among the others. Read reviews, watch videos on YouTube, and test the service on your own.
