I just found a problem when using alpha3, the IP displayed by arpl can only be the actual IP of the device. the IP address assigned to my device now is: 192.168.5.133, if I set the custom MAC address, the IP of the DSM system will become: 192.168.5.134, but arpl still shows: 192.168 .5.133. I can only use Synology Assistant to find the correct IP address.
