DHCP Server
DHCP allows networked devices to obtain information on the parameter of IP, Netmask, Gateway
as well as DNS through the Ethernet Address of the device.
To configure the router’s DHCP Server, select DHCP Server from the DHCP Server Mode drop-
down menu. You can then configure parameters of the DHCP Server including the domain, IP pool
(starting IP address and ending IP address to be allocated to PCs on your network), lease time
for each assigned IP address (the period of time the IP address assigned will be valid), DNS IP
address and the gateway IP address. These details are sent to the DHCP client (i.e. your PC)
when it requests an IP address from the DHCP server. If you check “Use Router as a DNS Server”,
the Router will perform the domain name lookup, find the IP address from the outside network
automatically and forward it back to the requesting PC in the LAN (your Local Area Network). Click
Apply to enable this function.
If you select DHCP Relay from the DHCP Server Mode drop-down menu, you must enter the IP
address of the DHCP server that assigns an IP address to the DHCP client in the LAN. Use this
function only if advised to do so by your network administrator or ISP. Click Apply to enable this
function.
