Windows 11 > Windows Hyper-V > Proxmox VE 7.2 > Debian 11.2 VM
In order for my Debian VM to be able to access the DHCP/network resources provided by devices on the outside of my Hyper-V server, I needed to enable Forged Transmits (MAC spoof) on my Proxmox VE 7.2 Hyper-V VM.
Now I can continue with my Debian VM installation with DHCP (netinstall).
