What Is NAT type F? And How To Change NAT Type F?

There are different aspects that you need to take care of while setting up a connection on your Nintendo Switch. One of them is selecting the NAT-type settings on Nintendo Switch.

NAT, short for Network Access Translation helps with assigning a distinct IP address to all the devices connected to your router.

When you have a single Internet Service Provider for many devices, you will only receive one IP address for each device connected. To split these IP addresses into a distinct one for each device, NAT settings are important.

You will receive different prompts about the NAT type on the Nintendo Switch. We will talk about What is NAT type F and how to change it, in this article.

If you see NAT type F on the Nintendo Switch, it means that the Nintendo Switch is unable to connect to other devices on the network. This will restrict you from playing with other players on the network since your IP is not verified at that point.

Let’s see what might be the issues behind this and how to solve them.


How to solve the NAT type F issue on the Nintendo Switch?


We have established the fact that if you see NAT type F on the Nintendo Switch, this means that your IP Address is not verified for playing with others on the network.

You need to get to the NAT type A status to be able to play online with other players. We will talk about the steps to get to NAT type A.

Fix 1: Remove the Nintendo Switch from the perimeter of the network firewall

A network firewall is an important tool to keep you secure online. However, in some cases, there are issues that stem from the misjudgment of the network firewall.

The official Nintendo Support team also mentions the first solution as removing the Switch from the range of network firewall scan.

You can add the Switch as an exception and the firewall will not interfere with the processes of the Nintendo Switch.


Fix 2: Put the console into DMZ

The Demilitarized Zone is a setting that can help you bypass the router’s security zone in order to function properly.

However, before you try to do this on your router and console, keep in mind that Nintendo Support warns you about the network security being compromised when you do this and it might lead to security breaches on your account.

Here are the steps that you can use to put your console in DMZ.

For the PC or device that you are using

Make note of the following information so that it can be used later.

  • Select the option for Manual IP address Settings
  • Select the IP address and hold the B button. This will delete the IP address that already exists.

  • Click on OK
  • Now click on Subnet Mask and press the B button again to delete the existing setting for the same.
  • Now enter the new Subnet mask that you noted in the above step.
