Configuring LAN
Parameters
This section describes how to configure the parameters of your LAN. (LAN refers
to that section of the network comprising your 56K LAN Modem and all of the
computers or devices attached to it by means of Ethernet cabling.) This section
describes the LAN parameters and then provides steps for their configuration.
Understanding LAN
Parameters
The LAN (Ethernet) Parameters window, shown in Figure 40, contains the
following fields.
Figure 40 LAN Parameters Window
Name
Displays the name for the 56K LAN Modem. This name is used for DNS. For
example, the name
LANmodem is translated to the IP address 192.168.1.1.
IP Address and Subnet Mask
The IP address is a unique address which identifies the 56K LAN Modem on a
network. The default address (192.168.1.1) is a private IP address which will be
translated automatically by the 56K LAN Modem for Internet access. You should
leave the default unless you are certain that this value must be changed.
The 56K LAN Modem attempts to use its default IP address to communicate with
the computer. If communication cannot be established, the 56K LAN Modem will
change its default IP address. If this occurs, the IP address shown in Figure 40 will
be different.
The subnet mask identifies the subnetwork to which your computer is connected.
You should leave the default unless you are certain that this value must be
changed.
