@steharv Be sure to use my example completely and not just edit your ltsp.conf file to match. My config file is known to work correctly.

# Don't function as a DNS server:
port=0

# Log lots of extra information about DHCP transactions.
log-dhcp

# Set the root directory for files available via FTP.
tftp-root=/tftpboot

# The boot filename, Server name, Server Ip Address
dhcp-boot=undionly.kpxe,,<fog_server_IP>

# Disable re-use of the DHCP servername and filename fields as extra
# option space. That's to avoid confusing some old or broken DHCP clients.
dhcp-no-override

# inspect the vendor class string and match the text to set the tag
dhcp-vendorclass=BIOS,PXEClient:Arch:00000
dhcp-vendorclass=UEFI32,PXEClient:Arch:00006

Be sure to replace each instance of <fog_server_ip> with the IP address of your fog server. There are several instances of that tag in the config file above.

The last bit is to ensure you have the correct version or later of dnsmasq or the config file will not work. From the linux command prompt key in dnsmasq -v. The version returned should be 2.76 or later. If its earlier than this you will have issues with uefi systems even if you use my config file exactly.
