FRITZ!Box with Fritz!OS 7.50: Port sharing and dynamic DNS

This tutorial was made using a FRITZ!Box running on OS version 7.50. Most of the functionalities will be analog on other OS versions, although they may look slightly different.

From the main menu (left sidebar) you go to Internet –> Permit Access –> Add Device for Sharing. That will bring you here:

The only thing you need to do here is to select your camera device. Either by its name in the network or by the IP address you noted earlier. Then you click “New Sharing”:

You fill out this form according to the image above and then click “OK”. That should be enough to establish the port sharing. In this example, we have connected a camera that works with the RTMP protocol (port 1935). In case you want to use a different protocol you need to use another port:

  • RTMP: 1935
  • HTTP: 80
  • RTSP: 554
  • HTTPS: 443

IMPORTANT: When connecting two or more cameras listening to one port, like e.g. 554, each camera must have its own unique external port.

For example: Camera1 external port = 554, Camera2 external port = 10544, Camera3 external port = 20544.

The last thing you need to do is to write down your dynamic DNS address. From the main menu, you go to Internet –> MyFritz!Account, In the center of the upcoming screen you will find it here:

If you don’t have a MyFRITZ! account yet, get one here. It’s easy!
