Please Note: This page may differ depending on your firmware version.
Step 4: Enter the Name, IP Address, and Port. The port number should go under both “Start” and “End.” Choose “Always” under Schedule and “Any” under Traffic Type.
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.
