# Configuring Routers and Firewalls

Each game which has an online component requires certain 'Ports' to be available to connect to that feature. [Ports are numbered connections that a computer uses to sort types of network traffic.] By default, all ports to the Internet, and most LAN ports are closed by your router so that traffic cannot flow through them. By opening just the ports required by a game, you will be able to connect to the online service while still keeping unwanted traffic closed. Please select your specific router type for basic instructions on opening ports:
