    @george1421 I’ve disabled the firewall on the server and I’m seeing the same results (only DHCP discover packets going through)Screenshot from 2023-06-26 15-44-40.png

      @Enigma Are you sure it’s booting PXE and not UEFI?

      In case it is UEFI, please disable secure boot on the machine.

          @Enigma Can you edit your /etc/dhcpd.conf file and change the instances of undionly.kpxe to undionly.kkpxe, if that still doesn’t work, attempt ipxe.pxe?

          Once you change the file, you’ll need to restart dhcpd service with:
          systemctl restart dhcpd

            @Tom-Elliott Ok, but the dhcpd.conf file is empty, where should add those details?

              @Enigma ok so how did you add dhcp services to your fog server (a blank dhcp config file would do exactly what you are seeing. ISCDHCP listening but not responding to any requests)? Did you add dhcp services when you installed FOG? Did you add the isc-dhcp server after fog was installed from your repo?

              So you’ll probably ask what goes in that file? Look at this example: https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence#Example_1 The dhcp pool will probably need to be updated to match the subnet of your dedicated imaging network.

                  @Enigma I would start with example #1 from that url. You will need to update the subnet, netmask range values so its appropriate for your isolated network. Anywhere you see the default 192.168.1.x you need to update so its appropriate for your imaging network.

                        @Tom-Elliott said in Isolated Network Setup (Stuck in Start PXE over IPv4):

                        /etc/dhcpd.conf

                        I might be wrong here but from the top of my head I wouldn’t think that’s the right config file. Guess it is /etc/dhcp/dhcpd.conf though.

                              Ok that is looking much better I now see the DORA process (Discover, Offer, Request, Ack). BUT there is something missing. When I look at the ethernet header I see the next server being 192.168.107.2 (hopefully is your fog server). The boot file is undionly.kpxe (this is good), but what is missing is the dhcp options 66 and 67. So that is telling me you are missing something in the config file. You are so close to having this work.

                              Could you post your complete dhcpd.conf config file?
