I work with a Business WOW!/Astound connection on Coax. I see about
400-500kb/s ~800pps continuous of Broadcast ARP Traffic coming in the
connection. That's not normal, is it? Basically, ARP Requests for
every IP address on the Cable plant. Shouldn't the cable modem be
filtering those, even if it is in bridge mode? The Mikrotik seems to be
handling them fine, but I have a Grandstream PBX on a public IP Address,
and I think that the volume may be causing it problems.
Is there a way in the mikrotik to filter any ARP that is not part of my
/29 subnet?
