In my case, after updating the firmware, the settings were reset to the factory settings and new functions were added, for example, when you select a Wi-Fi channel, you can see the noise levels of channels by other devices.
In this article I will give some examples of blocking IP addresses, MAC addresses, DHCP packets from DHCP servers, etc.

To block multicast ip addresses I will use ACL. Using an example of multicast, IPTV is broadcast via D-Link DGS-3612G and suppose that some channels need to be blocked, for this we create the following ACL rules:
