Use the Router for DHCP
To use the built-in DHCP server, click to select the DHCP Server option if it is not already selected. The IP
Address Pool settings can be adjusted so that up to 253IP addresses are available for use. The Starting IP
Address is the lowest available IP address (default = 10.1.1.2). If you change the IP address of the Router this
will change automatically to be 1 more that the IP address of the Router. The Ending IP Address is the highest
IP address number in the pool. Select the Lease Time from the pull-down menu. This is the amount of time that
a workstation is allowed to reserve an IP address in the pool if the workstation is disconnected from the network
or powered off. Lease time options vary from 1 hour to 1 week. DHCP client workstations on your LAN must be
properly configured to use DHCP service. Be sure to save the new settings.
Use the ISP’s DHCP Server
Some ISP’s can provide DHCP service for individual workstations on your private LAN. To use the service you
will need the IP address of the DHCP server on your ISP’s network. When this option is selected, the Router
automatically forwards DHCP requests from clients on your LAN to the outside DHCP server, and then forwards
the DHCP reply from the server to the client. DHCP Relay can be used for any WAN setting connection type.
DHCP Server Relay
To setup DHCP relay, click to select the DHCP Relay option. The menu will display the DHCP Relay IP entry
field. This is used to enter the IP address of the outside DHCP server to which requests are forwarded. Enter the
IP address of the ISP’s DHCP server and click the Apply button. DHCP client workstations on your LAN must
be properly configured to use DHCP from the ISP’s server. Be sure to save the new settings.
Disable the DHCP Server
To disable DHCP, click to select the No DHCP option and click on the Apply button. Be sure to save the new
settings.
