dnsmasq.conf for dhcp-proxy for pxe booting

# Set port to 0 so that dnsmasq knows its not being used as a DNS server.
port=0

# Configure DHCP-Proxy range
dhcp-range=192.168.0.255,proxy

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

# For debugging purposes, log each DNS query as it passes through dnsmasq.

# TFTP support
enable-tftp
tftp-root=/tftpboot

# Booting part
dhcp-match=gpxe,175					# gPXE sends a 175 option
dhcp-boot=net:#gpxe,gpxe.kpxe				# if the request does not match the gpxe rule (#gpxe) then tell the client (most likely standard PXE client) to boot gPXE
dhcp-boot=\Boot\pxeboot.n12,freeone,192.168.0.254	# in this case the request was made by gPXE and we tell it to boot win7 pxe image via TFTP (freeone is the host name, and 192.168.0.254 is the IP; in theory these 2 fields should not be necessary if the TFPT server is on the same machine as dnsmasq but...)

# Force sending of DHCP BOOT Packets
pxe-service=123456789, "Trigger", triggerfile, 0
# Not sure why the line above is needed and how it should be used; please see: http://www.thekelleys.org.uk/dnsmasq/docs/dnsmasq.conf.example
# L.E.: It triggers the sending of dhcp-boot data... actual data is not sent, hence dummy data
