Each router has 2 IP addresses: an internal IP address and an external IP address.

• Your router's internal IP address is what you use to talk to your router. Use this IP address to login to your router and configure it for things like port forwarding.
• Your router's external IP address is what the rest of the world uses to find you on the Internet. Tell this IP address to people who are trying to connect to you if you are hosting a game or other kind of server.
