@exsl So looking at your pcap your dhcp server is strange.

The first question is what device is your dhcp server?

I’m specifically looking at the OFFER packet.
You have the bootp part of the dhcp protocol set. But {next-server} points to 10.1.1.2 that is also your dhcp server. But the offer packet is not from a fog installer configured dhcp server, because the dhcp boot options are missing. There are no dhcp options 66 and 67 in that offer packet. I would say that dhcp OFFER packet is missing a LOT of stuff. That almost looks like a soho router giving out the dhcp info.

So again lets start out with what device is your dhcp server for this network?

Hello, thanks you for you help.
My DHCP server is my Fog server. Running on Almalinux 9.
I set “Yes” during the installation to make my fog server dhcp server.
