Troubleshooting Issues Related to NAT
While troubleshooting NAT related issues, it is recommended that you test your Internet connection after making any changes to the settings of your network to determine if the change improved your network's NAT type.
Networks with a more strict NAT type may prevent you from performing some online activities, such as connecting with other players online.
Both your NAT type and the NAT type any player you are attempting to connect with can affect the connection process. If you are having trouble connecting to a specific player, it is possible the issue may be caused by that player's NAT type.
What to Do:
Power cycle your gateway.Restarting your network device may resolve this issue. Ensure that it powers back on again prior to performing a connection test on the Nintendo Switch console.
Within your gateway's settings, place the Nintendo Switch console into a "DMZ."Setting up a DMZ will allow the Nintendo Switch system to communicate directly to the Internet and bypass the network firewall features of your gateway, which may be blocking some traffic necessary to connect with others.
While Nintendo provides this information for our consumers' use, it is up to each consumer to determine what security needs they have for their own networks, and to decide how best to configure their network settings to meet those needs.
If this does not resolve your issue and you continue to the next step, disable this setting on your router. A DMZ is not needed in combination with port forwarding.
Within your gateway's settings, forward ports to the Nintendo Switch console.If your network is blocking traffic needed for online communication, setting up port forwarding may resolve this.
Situation Not Resolved:
If you are still unable to connect, this may indicate an issue related to the network environment or wireless gateway being used.
If you would like to continue troubleshooting potential issues related to the gateway, contact the device's manufacturer for assistance with performing the following steps:
Updating the gateway's firmware
Resetting the gateway back to its factory default settings
