Network Address Translation (NAT) is a method used by routers to translate a public IP address (used on the Internet) into a private IP address (used on your home network) and vice versa.
When it comes to Boosteroid, you can run into NAT Strict type that causes connectivity issues in some multiplayer games.
This is mainly reflected in peer-to-peer games and games where the host is the player rather than the dedicated server.
However, that type does not affect the game on public servers.
Currently NAT Strict interferes with the following games:
Spintires: Mudrunner, Spintires: Showrunner
FIFA 21, FIFA 22 (when connected to friends)
Steep (when connected to friends)
Dying Light, Dying Light 2
Farming Simulator 19
Total War Warhammer 2,3

theHunter: Call of the Wild™
Nioh: The Complete Edition
