e in an ethernet frame from your default gateway's MAC address. That might fail if for any reason that MAC address changes, so I'd be a little afraid of this. Pretty sure it would work though. -Original Message- From: AF On Behalf Of Nate Burke Sent: Thursday, December 08, 2022 12

[AFMUG] Broadcast/ARP traffic on a CMTS Plant

2022-12-08 Thread Nate Burke
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
