Hello everyone. Thank you very much for this great project. My plan is to use a script to create/activate/deactivate port forwarding on a timer. The reason for this is that port 80 is required for LE extension on one NAS and then also on another, and I don't always want to have port 80 open permanently. I am using a Fritz Box 7590 and two Synology NAS devices. Ideally, I would also like to be able to control the call from an external web server, but if I understand correctly, the call must be made internally. What works is: Connect to the Fritz Box List the services List the port forwarding.

However, setting and deleting one does not work. I am using FRITZ!OS: 8.03 and Python 3.13.

I haven't found any relevant documentation either, so I don't know whether a parameter is missing or in the wrong format or something similar.
