Filter incoming ARP requests
Hi forum, I'm seeing a lot of ARP request packets ("who-has ... tell ...") in the guest VM, I suspect this is because of a larger VLAN and many unused IPs. Any solution to filter out the ARP broadcast packets flooding into VMs? I'm using PVE 7.4 in bridged mode. Thank you in advance.- r84q
