Duplicate IP - Minisforum MS-01

[adresner]

Have upward of 10 Proxmox hosts now, Dell, Supermicro, HP, etc... have never seen an issue like this. Have not even posted in here in a while because Proxmox is damn good. But clearly I don't understand something about Proxmox networking.. and hope to learn.

The duplicate IP 10.0.3.11 is coming off two different NICs from different bonds.

Getting warning in Unifi about Duplicate IPs. Coming off 2 different Bonds.




What am I missing here?

My hardware, Minisforum MS-01.

Hello,
setup for vmbr1/ bond0 other ipv4 network segment, as you did 10.0.3.0/24.
e.g. you have free 10.0.33.0/24.
