NAT (Network Address Translation) is a method routers use to translate a public IP address (used on the internet) into a private IP address (used on your home network) and vice versa.
On Boosteroid, you may encounter the Strict NAT type, which causes connection problems in some multiplayer games — mainly peer-to-peer games and games where one of the players hosts the match instead of a dedicated server.
Strict NAT does not affect playing on public servers.
Strict NAT currently causes problems in the following games:
Farming Simulator 19;
GTA V (when joining a friend’s server);
Call of Duty: Black Ops III.
