Hello.
After server reboot I received a MAC abuse notification from Hetzner.
Looking the networks device, now I have found this 2 mac in 2fwbr.
I have on vmbr0 opnesense with vmbr1 and vmbr2 as private LAN.
Others vps and xlc are directly connected on the vmbr0 with separate public ip's and dedicated MAC address relased from hetzner and someone at the same time on the vmbr2 private LAN
Why this happen?!?
> Unallowed MACs:

> ea:9b:09:ea:b3:4f - (code line 12 and 14)
