Section 4 - LAN Conguration
LAN Conguration
By default, the router functions as a Dynamic Host Conguration Protocol (DHCP) server to the hosts on the LAN
and WLAN network. With DHCP, PCs and other LAN devices can be assigned IP addresses as well as addresses
for DNS servers, Windows Internet Name Service (WINS) servers, and the default gateway. With DHCP server
enabled the router’s IP address serves as the gateway address for LAN and WLAN clients. The PCs in the LAN are
assigned IP addresses from a pool of addresses specied in this procedure. Each pool address is tested before it
is assigned to avoid duplicate addresses on the LAN.
For most applications, the default DHCP and TCP/IP settings are satisfactory. If you want another PC on your
network to be the DHCP server or if you are manually conguring the network settings of all of your PCs, set the
DHCP mode to ‘none’. DHCP relay can be used to forward DHCP lease information from another DHCP server on
the network. This is particularly useful for wireless clients.
Instead of using a DNS server, you can use a Windows Internet Naming Service (WINS) server. A WINS server is the
equivalent of a DNS server but uses the NetBIOS protocol to resolve host names. The router includes the WINS
server IP address in the DHCP conguration when acknowledging a DHCP request from a DHCP client.
You can also enable DNS proxy for the LAN. When this is enabled the router then as a proxy for all DNS requests
and communicates with the ISP’s DNS servers. When disabled all DHCP clients receive the DNS IP addresses of
the ISP.
