What is the Port Forwarding option on your ZyXEL Router?

Port forwarding is a method of routing connections over the internet to a device on a local network. By configuring port forwarding on your ZyXEL router, you can enable a variety of services such as remote access to a media server, hosting a game server, or self-hosting a website.

You should now be able to connect to your device via a web browser. Simply enter your hostname followed by the port number into the address bar. For example http://hostname.ddns.net:8000

Please Note: If you are using a mobile application, you will simply need to use your hostname to connect. The application should already specify the port when attempting to make the connection.
