DHCP_RANGE_x_START sets the first IP-Address that can be used.
DHCP_RANGE_x_END sets the last assignable IP-Address. Both variables DHCP_RANGE_x_START
and DHCP_RANGE_x_END could be left empty, so there will be no DHCP-Range, but hosts
with MAC assignments will receive their values from the other variables.
DHCP_RANGE_x_DNS_SERVER1 sets the addresse of the DNS-server for DHCP-hosts of
the network. This variable is optional. If left empty or omitted, the IP-address of the
matching network is used. Further it’s possible to set this variable to ’none’. Then, no
DNS-server is assigned.
DHCP_RANGE_x_DNS_SERVER2 same settings for the second DNS-servers
DHCP_RANGE_x_DNS_DOMAIN sets a special DNS-domain for DHCP-hosts for this
range. This variable is optional. If left empty or omitted, the default DNS-domain
DOMAIN_NAME is used.
DHCP_RANGE_x_NTP_SERVER sets the address of the NTP-server for DHCP-hosts in
this range. This variable is optional. If left empty or omitted, the IP-address of the
DHCP_RANGE_x_NET network is used. If set to ’none’, no NTP-Server is assigned.
DHCP_RANGE_x_GATEWAY sets the address of the gateway for this range. This variable
is optional. If left empty or omitted, the IP-address of the DHCP_RANGE_x_NET network is
used. If set to ’none’, no gateway is assigned.
DHCP_RANGE_x_MTU sets the MTU for clients in this range. This variable is optional.
DHCP_RANGE_x_OPTION_N allows the setting of user defined options for this range.
The available options are mentioned in the dnsmasq manual (http://thekelleys.org.
uk/dnsmasq/docs/dnsmasq.conf.example). They are adopted unchecked - this could raise
problems. This variable is optional.
Extra DHCP-Range
DHCP_EXTRA_RANGE_N sets the number of DHCP-ranges not assigned to local net-
works. For this a DHCP-relay has to be installed on the gateway of the remote network.
DHCP_EXTRA_RANGE_x_START first IP-address to be assigned.
DHCP_EXTRA_RANGE_x_END last IP-address to be assigned.
DHCP_EXTRA_RANGE_x_NETMASK Netmask for this range.
DHCP_EXTRA_RANGE_x_DNS_SERVER Address of the DNS-servers for this range.
DHCP_EXTRA_RANGE_x_NTP_SERVER Address of the NTP-server for this range.
DHCP_EXTRA_RANGE_x_GATEWAY Address of the default-gateway for this range.
DHCP_EXTRA_RANGE_x_MTU MTU for clients in this range. This variable is optional.
DHCP_EXTRA_RANGE_x_DEVICE Network interface over which this range can be reached.
