Does anyone know why I would have a bunch of entries in my arp table that are all zeros? 00:00:00:00:00:00

    It means something on the network attempted to ARP for that address, but no reply was seen by the firewall.

    It could mean that a device went offline, never existed, or that it has manual IP/subnet settings that are incorrect.
