CONFIGURING THE LAN
The LAN configuration sets up the interface between the modem 10/100Base-T LAN port and devices on the LAN.
The LAN is managed by your network administrator, who will make the decisions concerning its topology.
For instructions on setting up the LAN interface for a point-to-point modem application, go to Chapter 7:
Implementing a Point-To-Point LAN Extension.
BEFORE YOU BEGIN
Your network administrator will:
• Determine if you will use the modem Ethernet port in auto, full- or half-duplex mode.
• Identify a subnet value, including IP addresses and subnet masks.
• Determine if DHCP for the modem is enabled. If it is enabled, determine if the modem will be configured as a:
– DHCP client which receives an IP address from another device that is a DHCP server on the LAN
– DHCP server (determine the range of IP addresses the modem will need to serve, and identify the DHCP
gateway and DNS server)
– DHCP relay agent (determine the IP address to which the DHCP functions will be relayed)
• Determine if DNS Relay mode for the modem is enabled. If it is, identify the IP address for the DNS server.
CONFIGURE THE LAN
From the LAN Configuration page, configure the parameters for the LAN as indicated by your system administrator.
The default protocol for the LAN port is bridged.
Step Action
1 Select LAN on the menu bar, then select LAN Setup under LAN Options to access the LAN
Configuration page (see Figure 3-1).
