Package Configuration

• /etc/dnsmasq.conf

  # Listen on this specific port instead of the standard DNS port
  # (53). Setting this to zero completely disables DNS function,
  # leaving only DHCP and/or TFTP.
  port=0
  
  # Uncomment this to enable the integrated DHCP server, you need
  # to supply the range of addresses available for lease and optionally
  # a lease time. If you have more than one network, you will need to
  # repeat this for each network on which you want to supply DHCP
  # service.
  dhcp-range=192.168.3.200,192.168.3.250,12h
  
  # Override the default route supplied by dnsmasq, which assumes the
  # router is the same machine as the one running dnsmasq.
  # Do the same thing, but using the option name
  dhcp-option=option:router,192.168.3.1
  dhcp-option=option:dns-server,192.168.3.1
  
  # Set the boot filename for netboot/PXE. You will only need
  # this if you want to boot machines over the network and you will need
  # a TFTP server; either dnsmasq's built-in TFTP server or an
  # external one. (See below for how to enable the TFTP server.)
  dhcp-boot=syslinux.efi
  
  # Enable dnsmasq's built-in TFTP server
  enable-tftp
  
  # Set the root directory for files available via FTP.
  tftp-root=/var/tftp
