    I noticed that when I boot the FOG ipxe kernel from USB on a different subnet than where the FOG is I get asked to enter the tftp server address. This doesn’t happen on the same subnet. Is there something I need to adjust on the FOG server?

      @brakcounty what is the DHCP server that you’re using for this environment? are there managed switches in between subnets?

        @p4cm4n Yes there are managed firewalls, DHCP servers, switches between the FOG server and the client workstation in the screenshot above.

          @p4cm4n You know now that I think about it, if the remote DHCP server does not have the fog server IP set as the DHCP relay server, then this could be why ipxe process is asking for the tftp server.

            @brakcounty could be.
            its interesting that its getting to IPXE already, so its getting SOMETHING from SOMEWHERE.
            try it out and lets see.

              @p4cm4n ipxe is loaded from the USB drive, EFI/BOOT/bootx64.efi. This file is actually the ipxe.efi kernel file taken from my FOG server in /tftproot/
