Determining IP Addresses for the Subnet

DETERMINING IP ADDRESSES FOR THE SUBNET

If you have not already done so, you need to determine the IP addresses and subnet masks for the Megabit Modem 410F and 420F and each device on their LANs. This will enable you to configure and manage the modems from the 10/100BASE-T LAN port or ADSL (WAN) port, as well as transmit information to and receive information from devices throughout the system.

How to set the IP addresses and subnet masks for the Megabit Modem 410F and 420F and the devices on their LANs depends upon whether you configure the system for bridging, routing, or bridging and routing mode.

Managing Modems in Bridging Mode

The following is a sample configuration for setting the IP addresses and subnet masks for managing modems when bridging mode only is enabled. Note that in bridging mode, the

410F LAN and 420F LAN must be on the same IP subnet. When you connect to a modem either locally or remotely, use the modem 10/100BASE-T LAN port IP address.

The IP addresses in the figure below are for example only. Acquire your own IP addresses from your network administrator or service provider.
