Create a Port Forward for Subnautica: Below Zero in your Router

Subnautica: Below Zero is Unknown Worlds Entertainment's Adventure and Survival game released in 2021.

Subnautica: Below Zero has the following styles of play.

• In an adventure game you generally play through a story, usually as the protagonist. They rely heavily on story telling and can be inspired from books or movies.
• In a survival game you simply need to stay alive. Some have waves of enemies that get harder with each wave. Many are horror based, supernatural, or post-apocalyptic. They generally focus on conserving resources such as ammo and health, and sometimes employ elements of stealth.

When you are playing Subnautica: Below Zero you might need to forward some ports in your router. Forwarding ports is a useful trick in gaming because it can really help to make your network connection most stable and intermittently even faster. Routers were not designed to allow incoming network requests and some games can play tremendously better if an incoming connection is forwarded through the router to the game.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

When shopping for a VPN, make sure that they meet the following criteria:

• Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
• Make sure that your VPN provider has lots of exit nodes all around the world.
• Check that your VPN will not affect your speed.
• Verify that your VPN provider uses WireGuard as the underlying protocol.
• Many people prefer a VPN provider that is not based in the United States.

This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.

Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.

Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.

Before you can forward a port you need to know the following things:

• The IP address of your router.
• The IP address of the device that the game will play on: either your computer or your console.
• The TCP and UDP ports to forward.

The easiest way to locate your router's IP address is to run our free Router Detector utility. It's a part of the Network Utilities suite of tools and it's completely free to use.

A smart way to forward your ports is to use Network Utilities. Since Network Utilities allows you to both forward and un-forward ports easily you can keep your network security maximized, and then forward ports only when you need them. Alternatively you can do it by hand.

The process for forwarding a port is usually:

• Open a web browser and navigate to your router's IP address.
• Find your routers port forwarding section.
• Put the IP address of your computer or gaming console in the correct box in your router.
• Put the TCP and UDP ports for your game in the corresponding boxes in your router.
• On occasion you have to reboot your router for the changes to take effect.
