Routers feature a firewall that blocks incoming network requests. While this feature is vital in protecting your network against malicious traffic and hackers, it limits your gaming experience. If you want to get the best experience when playing FSX, you will need to deal with this limitation by forwarding specific ports in your router. Through FSX port forwarding, you can unblock the firewall to allow incoming connections and forward these connections through the router to your game.
