Are you concerned with manually entering every MAC address to your filter list? Yeah, that will be a hassle but it's your use case.Ah I see. So I just had the order wrong? So have all mac address block as the last filter rule, and preceding filter rules are "allow" for each mac address?
Is there a more efficient way to do this than to manually make a new allow filter rule for each mac address?
You can inspect all MACs on your network and figure out their common OUIs (first 3) and maybe some of their remainder octets and use a wildcard or forgo filtering it in this way and use rules from your firewall/DHCP server instead. You may have more flexibility with not using MAC filters as in the video that device only supports 64, but I assume you can reconfigure a global setting to have more.
