I have a three node cluster, wherein vmbr1 is dedicated as a wan interface. I recently upgraded the motherboard of two of the nodes, and their nics seems to fight with themselves for the wan ip when they run my router vm (pfsense), because they seem to have two mac addresses.
The wan interface will go down within an hour or two of reboot and I can see in dmeg:
That mac address does not belong to any device on my network. I can only assume that it comes from the onboard i350 nics of the previous very similar motherboard, because all 3 motherboards with i350 nics have macs that start with 00:25:90.
This can occur when the node hosting the router vm is the only device connected to the ONT, so the rouge mac addresses must be coming "from within".
If I migrate the vm to the other node with a recently upgraded motherboard, the same problem occurs, but the mac address is slightly different. Once again, it does not belong to any device currently on my network, and I assume it belongs to the motherboard that the OS disk was previously attached to.
I've been grepping around the systems, but I can't find an instance of that mac anywhere. I suspect it mat not be in a plain text file.
Any help is much appreciated., as I can't bring myself to just reinstall the OS or edit my real mac to match the rouge mac (yuk!).

Code:
arp: 00:25:90:ed:70:43 is using my IP address 71.187.2.56 on vtnet1
