Hi
I installed pi-hole on a VM on Proxmox and enabled DHCP. All other VM's und CT's on Proxmox can get IP addresses. But other hosts in my home network do not get a IP address. All firewalls are disabled in Proxmox.
Any ideas?
Thank you
 
Do you have the pi-hole VM attached to a bridge which also has as bridge port the physical NIC your PVE host is connected to your home network? As otherwise the hosts in your physical network cannot communicate with your VM.
 
Communication does work, only the DHCP response will be blocked.
My Proxmox is running on a minisforum MS-01. It has 2 nics. I switched to the other network interface and now dhcp works.
