In the meantime, I found out via Reddit that this is definitely how it works. :)

If you want to use it as an access point with the Bridge Mode, this could be possible according to the supplier. However, I recommend that you discuss this again in more detail with our consulting team in connection with your specific device configuration: https://helpcenter.digitec.ch/hc.... The LAN connection to the repeater should run via one port and you can then use the other port to connect to an end device/switch or a repeater again.
