What is NAT type B on Switch? (2023)

Is NAT Type B good for switch?

For Nintendo consoles, NAT Types range from Type A (best for peer-to-peer communication) to F (unable to complete peer-to-peer communication). If your NAT type is A or B, your console is connected properly and shouldn't run into issues.

Restarting your network devices may resolve this issue. Ensure both devices power back on again prior to performing a connection test on the Nintendo Switch console.

NAT type B is compatible with most other NAT types as well. Users with NAT type C network environments may have difficulty connecting to some users with more restricitive NAT types. NAT Type D indicates that your network will make it difficult to connect with other players.

Open NAT: This is the ideal NAT type. With an Open NAT, you should have no issue connecting to other players, as well as being able to chat and party up with players with no problem. You are also able to host multiplayer games with people of any NAT type.

In some scenarios, you may be able to resolve connectivity issues by refreshing the Network Address Translation (NAT) table. To refresh the NAT table on a router where UPnP is already enabled, you need to disable UPnP, save your changes, and then power cycle your router.

If you are having problems, it may be due to a glitch with your connection and may be resolved with a simple reboot. If your NAT Type is Moderate or Strict, this generally indicates that there is some sort of restriction or blockage that is preventing your console from communicating properly.

The Nintendo Switch gaming device is not able to connect to online games. Nintendo Switch work on the basis of UPnP (Universal plug and play). UPnP will allow dynamic port opening for TCP and UDP to forward Nintendo gaming traffic and Palo Alto Networks devices are not compatible with UPnP traffic.

Can different NAT types play together?

Users with a Strict NAT type can connect to games hosted by a user with an Open NAT type, however, if a game supports multiple users, they will get disconnected if a user with Moderate NAT type joins the same game.

Ports needed for Nintendo Switch Port Forwarding

UDP: 1-655359 or 45000-65535* TCP: 6667, 12400, 28910, 29900, 29901, . 29920.

The Bottom Line is. Port Forwarding is not that risky because it relies on your network safety and the targeted ports that you are using. The whole process is actually safe as long as you have a security firewall or a VPN connection on your computer or network.

PlayStation Network

PlayStation defines NAT as three different types: Type 1: Connected directly to the Internet. Type 2: Connected to the Internet via a router. Type 3: Connected to the Internet via a router.

For example, Moderate/Type 2 NATs can only connect with gaming consoles or PCs using Moderate/Type 2 or Open/Type 1 NAT, and Strict/Type 3 NATs can only connect with gaming consoles or PCs using Open/Type 1 NAT. Ultimately, an Open/Type 1 NAT will provide the best connection quality.

Sometimes your Internet connection restricts available ports to a strict NAT type 3. This usually is the case when connecting from campus WiFi, office networks, public WiFi networks etc. In this case, in order to get a moderate NAT type 2, you'll have to bypass the port restrictions on these networks.

If you are having problems, it may be due to a glitch with your connection and may be resolved with a simple reboot. If your NAT Type is Moderate or Strict, this generally indicates that there is some sort of restriction or blockage that is preventing your console from communicating properly.
