Part 2. Configuring IP properties on the USB PC.
{
XE "USB:configuring IP on PC"
}
Now that the USB driver installation is complete, you
must configure the USB PC so that its IP properties place it on the same subnet as the
ATU-R130’s USB port. There are two ways to do this:
?
The ATU-R130 is configured to assign an appropriate IP address to the USB PC. If
you want to use this automatic assignment feature, called “DHCP server,”you
must configure the USB PC to accept dynamically assigned IP information. Follow
the instruction on pages 7 through 9 that correspond to the operating system
installed on the PC.
?
If you want to assign a static IP address to the PC, follow the instructions on page
10 and use the following information.
?
In the Network and Dial-up Connections window, be sure to select the icon that
corresponds to your new USB connection (not the one that corresponds to your

Ethernet NIC). When you display the properties for the icon, the following text
should display in the Connect Using text box:
GlobeSpan USB IAD LAN Modem #n
?
The USB port on the ATU-R130 is preconfigured with these properties (you
cannot change these values):
USB port IP address:
198.168.1.2
USB port subnet mask:
255.255.255.0
Therefore, your PC must be configured as follows:
IP address:
192.168.2.
n
where
n
is a
number from
2
to
254
.
Subnet mask:
255.255.255.0
Default gateway:
198.168.1.2
Default Router Settings
In addition to handling the DSL connection to your ISP, t
{
XE "Default configuration"
}
he ATU-R130 ADSL/Ethernet router can provide a variety of services to your
network. The device is preconfigured with default settings for use with a typical home
or small office network.
Table 1 lists some of the most important default settings; these and other features
are described fully in the subsequent chapters. If you are familiar with network
configuration, review the settings in Table 1 to verify that they meet the needs of your
network. Follow the instructions to change them if necessary. If you are unfamiliar
with these settings, try using the device without modification, or contact your ISP for
assistance.
Before you modifying any settings, review Chapter 4 for general information about
accessing and using the Configuration Manager program. We strongly recommend
that you contact your ISP prior to changing the default configuration.
Table 1. Default Settings Summary

Default Setting
Explanation/Instructions
DHCP (Dynamic
Host Configuration
Protocol)
DHCP server enabled with two pools
of addresses:
For LAN computers:
192.168.1.2 through 192.168.1.13
For USB computer:
192.168.2.2 (for both, subnet mask
=
255.255.255.0)
The ATU-R130 maintains a pool of 12
private IP addresses for dynamic
assignment to your LAN computers and a
pool containing 1 IP address for
assignment to your USB computer. To
use this service, you must have set up
your computers to accept IP information
dynamically. See Chapter 6 for an
explanation of the DHCP service.
NAT (Network
Address Translation)
napt rule enabled
Your computers’
private IP addresses
(see DHCP above) will be translated to
your public IP address whenever they
access the Internet. See Chapter 7 for a
description of the NAT service.

Typically, you will not need to change this
address. See Chapter 5 for instructions.

Getting Started with the Configuration
Manager
The ATU-R130 includes preinstalled program called the
Configuration Manager
, which
{
XE
"Configuration Manager:overview"
}
provides an interface to the software installed on the
device. It enables you to configure the device settings to meet the needs of your network.
You access it through your web browser from any PC connected to the ATU-R130 via
the
LAN port.
Note
The ATU-R130 may already be configured to provide Internet
connectivity for your network. If it works properly with the
preconfigured settings, then you may not need to use the
Configuration Manager. Contact your ISP to determine which
settings you may need to change, if any.
Accessing the Configuration Manager
{
XE "System requirements:for Configuration Manager"
}{
XE "Web browsers:compatible
versions"
}{
XE "Login:to Configuration Manager"
}
The Configuration Manager program is
preinstalled into memory on the ATU-R130. To access the program, you need the
following:
?
A PC or laptop connected to the LAN port on the ATU-R130.
?
A web browser installed on the PC
{
XE "Web browser: version requirements"
}
. The
program is designed to work best with Microsoft Internet Explorer® version 5.0,
Netscape Navigator® version 4.7, or later versions.
You can access the program from any computer connected to the ATU-R130 via the LAN
or USB ports.
1.
From a LAN computer, open your web browser, type the following URL in the web
address (or location) box, and press
<Enter>
:
Or, from the USB computer, type:
These are the predefined IP addresses for the LAN and USB ports on the ATU-R130.

You can change the password at any time (see Changing Your
Login Password on page 17). The user name cannot be changed.
Functional Layout
{
XE "Navigating"
}
Configuration Manager tasks are grouped into categories, which you
can access by clicking the tabs at the top of each page. You can click on these to display
the specific configuration options.
A separate page displays for each task in the task bar. The left-most task displays by
default when you click on a new tab. The same task may appear in more than one tab,
when appropriate. For example, the Lan Config task displays in both the LAN tab and the
Routing tab.
