The user must configure the IP Address and the Subnet Mask. To use the DHCP
service on the LAN, select the Enable DHCP server checkbox, and enter the Start
IP addresses, the End IP address and DHCP lease time. This configures the IAD to
automatically assign IP addresses, default gateway address and DNS server
addresses to each of your PCs.
Note that the IAD's default IP address is 192.168.1.1 and the default private
address range provided by DHCP server in the IAD is 192.168.1.2 through
192.168.1.254.
Select Enable DHCP Server Relay (if required), and enter the DHCP Server IP
Address. This allows the Router to relay the DHCP packets to the remote DHCP
server. The remote DHCP server will provide the IP address.
To configure a secondary IP address for the LAN port, click the box as shown below.
