DHCP Server
The Dynamic Host Configuration Protocol (DHCP) server automatically assigns IP addresses to each
host on the LAN. It also provides the default gateway address, primary and secondary Domain Name
System (DNS) server address, and primary and secondary Windows Internet Naming Service (WINS)
server addresses.
The following procedures are used to change the DHCP settings.
·Select LAN on the Internet Module Configuration screen. The following screen is displayed.
·Select DHCP Server. The following screen is displayed.
·LAN Gateway address defines the IP address of the router. It is set by default to 192.168.1.1. All
traffic destined for the Internet is sent to this address and the Internet module then forwards the

EncoreCX
Internet Module Manual
12
traffic. This address can be changed if a different address range is required, if static addressing is
used, or if all IP traffic is to be sent to a different gateway on the LAN.
·The LAN Gateway Subnet Mask defines the subnet mask to be applied to the LAN Gateway
address. This can be changed if the LAN Gateway address is changed from the default setting.
·The Primary DNS Server is the address to which all requests to resolve domain names are sent.
With the default setting 192.168.1.1, all requests are sent to DNS relay, which in turn forwards the
requests to a DNS server at the ISP. If a DNS server other than the one assigned by the ISP is
required, the IP addresses should be inserted in the Primary and Secondary DNS server fields in
the DSL or Broadband Profile and DNS Relay Enabled on this screen.
·The Secondary DNS Server is set by default to 0.0.0.0. to forward requests to the secondary DNS
server at the ISP. If a different secondary DNS is to be used, the address is entered here.
·The Primary WINS Server is the address of the primary WINS server on the LAN.
·The Secondary WINS server is the address of the secondary WINS server on the LAN.
·The Starting IP address is the first IP address to be automatically assigned to a LAN host. The
default setting is 192.168.1.2. Subsequent addresses assigned follow in ascending order. A
different starting IP address can be assigned if required and subsequent numbers in the range will
follow in ascending order.
·The Number of Addresses defines how many IP addresses the DHCP server can assign. Up to
100 addresses can be allocated and the default setting is 100.
·Duration Units defines the units of time used for the IP address lease. Days, Hours or Minutes can
be defined. The default setting is Days.
·The Lease duration is the period for which the IP address is assigned to a host. The default setting
is 3 days.
·DHCP Server Enabled - this box is checked by default. The DHCP Server should only be turned
off if another DHCP server is connected to the LAN or static addressing is used.
·DNS Relay Enabled - this box is checked by default.
·Click Save.
·Click Send.
·For the changes to take effect, press RESET when prompted on the main screen of the EncoreCX
Programming and Maintenance software or press the reset button on the Internet module MDF.
