Proxmox VE is a rogue DHCP

PVE doesn't host a DHCP server out of the box - either you set one up, or one inside one of your guests is exposed/broadcasting..

that's what I thought, but i don't have another on that host. in fact, the rest of the guests are linux servers or windows 10, and the Windows Server DHCP log specifically calls out the host's IP as the culprit. Our other IT guy, who set these up initially, said it's likely a firewall issue on the host, but didn't give specifics. AFAIK, we don't ahve another enabled dhcp on the network.
