I give up, for days I have trying to figure it out. So any help will be very welcome.

I have a Proxmox virtualization server and everything works fine, except that none LXC (Linux Container) can get an answer from the DHCP server. I have the following:

  • LXC + DHCP client = No
  • LXC + static IP = Yes
  • VM + DHCP client = Yes
  • VM + static IP = Yes

Therefore I know it isn't a firewall or networking issue. My best guess it is a kernel issue, but again I have another Proxmox server on the same network (and same Proxmox cluster) that works fine.

Sorry for the fuss.

I am not sure yet how it happened or where it was happening, but the problem was solved once I changed the MAC address of the Linux container.

And since I didn't keep the old address, I can't replicate the problem. But I can assume the problem was on the network layer 2/some arp table.

Thank you all anyway.
