Thanks for the info that did the trick for me all up and running now. You can mark this as resolved.

@george1421 my newbie mistake! this is now resolved

@george1421 U r the man ! and yes it would make sense I stop the dnsmasq service and it worked 1st time.

BTW on Fedora 23 server it refers you back to systemctl stop dnsmasq.service

Quick reg all done

@george1421 Plugged the WAG 120N back in to see if it is router related and got the same error message?

@george1421 it is running the firmware that it came with I haven’t mugged around with the firmware at all. OK let me explain. I used to have a Ubuntu flavor Fog server working with a Cisco/linksys wag120n and this combo worked like a dream for Win 7 boxes. Not so much for Win 8.1 and 10. As the company I work for are now starting to roll out Win 10. There fore I need a fog box that can make images for Win 10. Reading a bit up on the subject I decided to use Fedora 23 server with the TL-MR4320 and to do gigabyte interfaces. To speed up the image process up a bit.

There is no device on the network for 192.168.1.20 and pings don’t work to 192.168.1.20 anyway. Basically the network is 1 X fog box(fedora 23 server) 1 X TP-Link router 1 X win 10 box

@george1421 Yes my Fog server is on 192.168.1.102, the default Gateway is a TP-Link TL-MR3420 router.
This install centos 7 line in the boot menu bug me immensely. As my DHCP conf file and the LTSP .conf file does not refer to this at all.

LTSP file:
port=0
log-dhcp
enable-tftp
tftp-root=/tftpboot
dhcp-boot=undionly.kpxe.0,192.168.1.102
dhcp-option=17,/images
dhcp-option=vendor:PXEClient,6,2b

pxe-service=X86PC, “Boot from network”, undionly
pxe-service=X86PC, “Boot from local hard disk”, 0
dhcp-range=192.168.1.102,proxy

DHCP file:
option space PXE;
option PXE.mtftp-ip code 1 = ip-address;
option PXE.mtftp-cport code 2 = unsigned integer 16;

}

I used the following:
https://wiki.fogproject.org/wiki/index.php/Fedora_21_Server

and get the error message as per attached screenshot

https://www.dropbox.com/s/ngu4lxokblzzgyw/WP_20160614_001.jpg?dl=0

and no other DHCP server/devices in the network

The fog server issues IP address as the client machine then gets an ip address as per DHCP. The boot menu comes up press F8 for boot menu
When I select boot from network I just receive boot server: X.X.X.X TFTP.
PXE-M0F : Exiting Intel Boot Agent
Selected boot device failed. Press any key to reboot the system

Thanks it is now working

I have successfully installed Fog but without DHCP, is it possible to change this after installation. Or be uninstall ? and re-install with DHCP?
as this wiki link is a bit outdated:
