4.4 DNS Server Setting
The ADSL2+ Router is configured by default to forward the DNS server address you enter in the DNS
page, shown below, to all DHCP clients on your LAN. When DNS is enabled, the DNS clients on the LAN
will automatically get DNS settings relayed from the ADSL2+ Router as they are entered here. Alternatively, if
DNS Status is disabled, workstations must be configured to initiate DNS requests for each session, and
therefore you must configure DNS settings for the workstations.
Figure 4-9. Configure DNS IP address
Usually an ISP will provide you with one or two DNS server IP addresses. Enter these IP addresses in
the available entry fields for the Primary DNS Server and the Secondary DNS Server.
If you do not want to use the ADSL2+ Router as a DNS proxy agent, change the DNS Status to
Disabled.
When you have configured the DNS settings as desired, click the Apply button. Be sure to save the
settings.
4.5 Configuring the LAN Connection
The first step in configuring your LAN is to determine the IP address scheme that the computers on your
LAN will use. The 192.168.1.x (where x can range from 2 to 254) IP address range has been dedicated for
home and small office use. The ADSL2+ Router ADSL router is configured with a default IP address of
192.168.1.1, and a subnet mask of 255.255.255.0. The next IP address available for use on a LAN is
192.168.1.2. This is why the IP address range begins with an x = 2, because when x = 1, that identifies the
ADSL2+ Router on your LAN. The IP address where x = 255 has a special meaning (it is the broadcast
address for your LAN). When you configure PCs on your LAN, the ADSL2+ Router’s IP address
(192.168.1.1) will become the Default Gateway IP address for all PCs on your LAN.
You can configure the ADSL2+ Router’s LAN IP address to any IP addressing scheme that meets the
needs of your LAN. Many users will find it convenient to use the default settings together with the DHCP
service to manage the IP settings for their LANs. The IP address of the ADSL2+ Router is the base address
used for DHCP. In order to use the ADSL2+ Router for DHCP on your LAN, the IP address pool used for
DHCP must be compatible with the IP address of the ADSL2+ Router. The IP addresses available in the
DHCP IP address pool will change automatically if you change the IP address of the ADSL2+ Router. See
the next section for information on DHCP setup, as described below.
