Hello everyone, I've been facing ARP Conflict problems in a Mikrotik installed on Proxmox, I've struggled a lot on Mikrotik and I didn't find the error. On the Mikrotik forum, I received a suggestion that the problem could be in Proxmox. Analyzing Proxmox I saw a way out that made me curious, we have a Public IP range that is only used statically, so there should be no requests by any device from these addresses, but even so, there is a flood of them.

I would like to know how I can know:

1º If these requests by addresses make any sense, considering that there is no DHCP server that provides them in any ProxMox service?

2º If the Mikrotik ARP conflict can be caused by some configuration made in Proxmox?

3º Any tips are welcome!

I don't know if this situation is related to my ARP Conflict problem in Mikrotik, which has as characteristics, many IPs Assigned to the same MAC addresses.

Note: My public network was overshadowed with the physical network: 111.222.333.0/24.
