Chapter 3: Provisioning April 14, 2006

Step	Action
2	b. Configure the following parameters when DHCP server is enabled for the modem:
(cont.)	– DHCP Range Low
	The lowest IP address value that the modem can serve when configured as a DHCP Server. A
	maximum of 20 IP addresses can be served by the modem. This IP address value is provided by
	your LAN administrator and must be on the same subnet as the modem LAN port.

–DHCP Range High

The highest IP address value that the modem can serve when configured as a DHCP Server. A maximum of 20 IP addresses can be served by the modem. This IP address value is provided by your LAN administrator and must be on the same subnet as the modem LAN port.

–Default Lease Time

The default amount of time, in seconds, that a device on the LAN can be bound to the IP address it was served before the lease expires. This value is provided by your LAN administrator.

–Max Lease Time

The maximum amount of time, in seconds, that a device on the LAN can be bound to the IP address it was served before the lease expires. This value is provided by your LAN administrator.

–DHCP Default Gateway

Enter the IP address of the DHCP default gateway that is provided by the LAN administrator for devices on the LAN. After you configure this IP address, the modem provides this IP address as a default DHCP gateway to requesting DHCP clients (such as PCs) on the LAN. If there are no gateways on the LAN, then the modem LAN port IP address can be assigned as the gateway.

–DHCP DNS Server

Enter the IP address of the Domain Name System (DNS) server that will translate human-readable addresses to IP addresses. The DNS server can be either on the LAN or the WAN side of the modem. The modem provides this IP address as a default DNS server to requesting DHCP clients (such as PCs) on the LAN. If the DNS server is on the LAN side of the modem, acquire the IP address from your LAN administrator. If the DNS server is on the WAN side of the server, acquire the IP address from the service provider.

If you enabled DNS relay on page 3-3and entered a DNS server IP address, then enter the modem LAN port IP address as the DHCP DNS server.

•DHCP relay agent—The modem forwards the request for an IP address, DHCP default gateway, and DNS server IP address to a device acting as a DHCP server. The DHCP server can be either on the LAN or the WAN side of the modem. If on the LAN side, acquire the IP address from your LAN admin- istrator. If on the WAN side, acquire the IP address from the service provider.

a. Select DHCP relay agent, then click Configure to access the following DHCP Server page.

b. Enter the DHCP Server IP address for the device to which the modem will forward DHCP services requests, then click Apply.
