How to Port Forward Subnautica
When you are playing Subnautica 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.
Before You Forward a Port
Before you can forward a port you need to know the following things:
- The IP address of your network router.
- Your gaming machine's IP address.
- A list of TCP and UDP ports that need to be forwarded.
How to find your router's IP Address
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.
How To Forward Ports
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 normal process for forwarding a port is:
- Open a web browser and navigate to your router's IP address.
- Locate your routers port forwarding section.
- Put the IP address of your computer or gaming console in the proper box in your router.
- Put the TCP and UDP ports for your game in the corresponding boxes in your router.
- Intermittently you have to reboot your router for the changes to take effect.
