Configuring a LAN	To configure a LAN Modem that will use the Single-User scenario to access a

	because the remote LAN Modem’s IP address is identical, by default.
Before You Start the	Before you start the configuration, you should already have completed the
Configuration	following steps:
	■ Run the EZ-LAN Wizard or performed the TCP/IP and IP Address check on the
	workstation you are using to configure the client LAN Modem, as described in
	Chapter 3.
	■ Installed the client LAN Modem hardware, as described in Chapter 4 (steps will
	differ slightly if you are using a regular 56K LAN Modem).
	■ Changed the LAN Modem’s IP address, as described below (this prevents a
	possible IP address conflict with the server-side LAN Modem).

Changing the LAN Modem’s To change the IP address, do the following.

IP Address

1From the LAN Modem Main Configuration Page, click the LAN Parameters icon. The LAN (Ethernet) Parameters window appears.

2In the IP address field, change the IP address to 192.168.2.1.

The LAN Modem re-initializes itself. The front panel LEDs flash, indicating a reset in progress.

Once the LAN Modem IP address has been changed, you can no longer access the LAN Modem until your workstation has been restarted and has acquired an IP address belonging to the new LAN Modem subnet.

3Restart your workstation.

The default IP address for the local LAN Modem will have been changed to 192.168.2.1. Similarly, all attached workstations, once re-started, will utilize an IP address belonging to this new subnet (192.168.2.x).

Because one of the initial steps of the server-side configuration is to assign each LAN Modem a separate Site identity, (A, B, or C), which can cause the LAN Modem to change its IP address, configuring the LAN Modem for server-side
