4 Configuring the computer's firewall

A firewall on the computer with the FRITZ!Box USB remote connection can interfere with the communication between the software and the FRITZ!Box:

  • Configure an exception for the FRITZ!Box USB remote connection software in the firewall on the computer with this application,
    • or:
  • Configure the firewall so that it allows incoming and outgoing TCP and UDP connections from port 2066 on the FRITZ!Box to any destination ports on the computer.

    Note:Refer to the manufacturer of the firewall for information on how to set it up, for example consult the manual.

The FRITZ!Box and the computer are now completely configured to use the FRITZ!Box USB remote connection software. We are not aware of any further measures for this issue. Further causes could be disturbances or an error of the operating system or firewall on the computer.
