NAT Related Issues


My games tells me that I have a closed NAT, a strict NAT or a moderate NAT type. How do I get an Open NAT type?


Having a closed, strict or moderate NAT type can prevent you from fully enjoying all the features of an online multiplayer game.

NAT stands for Network Address Translation. It is, roughly speaking, a method of directing the traffic coming from the Internet - whether it's from a website, a game server or a P2P network - to the right device - computer, console, tablet, etc. -  on your local network. Since this method takes into account both the device and the origin of the traffic engaged in the 'conversation', you can very well have an open NAT type for some services or game, and a closed one for others.

The piece of hardware responsible for NAT on a local network is the router. While other factors might negatively impact your NAT, your first step to troubleshoot NAT related issues should be to check your router configuration.

This last piece of information can be good news, or not:
- Some routers are easier to configure than others
- If you are using a shared internet connection in a communal building - dorm, military base, hospital, etc. - you might not have access to the router
- Some ISP might ostensibly provide you with a router, but put you behind a second router-like device that you do not have access to (your router is then not directly connected to the internet, but to a second 'local' network. This scenario is called Double NAT)
