@Kram-Man Is your main ipxe server running ipxe as the bootloader or syslinux? If its truely iPXE then on the FOG server, in the tftpboot directory there is a file called default.ipxe At the bottom of that is a chain load command or chain load the default.ipxe You can look at this line on github. https://github.com/FOGProject/fogproject/blob/a4bb1bf39ac53c3cbe623576915fbc3b5c80a00f/src/ipxe/src/ipxescript#L32 Just replace ${next-server} with the IP address of your fog server.
