FRITZ!Box Reconnect

 Activate UPNP

By default, UPNP is already activated. If not, follow these steps:

Enter the login page of your FRITZ!Box, typically  http://fritz.box or http://192.168.178.1 and login.

Click on “Settings” in the overview.

1. Click on “System” (shows the submenu)
2. Click on “Network Settings”
3. Activate UPNP
4. Apply your changes

Important for users of FRITZ!OS 8.25 and higher

Starting from version 8.25, the option “Allow independent port sharing and the disconnection and reconnection of the internet connection for this device” must be explicitly enabled for the respective device for security reasons.

Go to Internet -> Permit Access…
Click on Add device for sharing/permit access and enable the option “Allow independent port sharing and the disconnection and reconnection of the internet connection for this device.”
