Starting from 10(or9) debians, I observe the problem of the work of isc-dhcp-server, if it is on a virtual machine.
I have clean default install of proxmox7 and debian 11 with isc-dhcp-server on VM. No vlans, all simply.
No apparmor,selinux of firewall (nft iptables etc on the vm)
Tcpdump on the node and vm show only discover and offer packets, no requests.
I running tcpdump on external PC, and no looking offers packet.
VM with clean windows 10 on this node not get ip address too.
If i place this DHCP config on the Proxmox node, or Centos7 VM - all working.
