Chapter1 Introduction
Overview of the DSL/Cable Gateway
The DSL/Cable Gateway is a small desktop gateway that sits between your local Ethernet network
and a remote network (e.g., the Internet). The DSL/Cable Gateway contains an Ethernet EWAN
port connecting to an external ADSL/Cable modem, and a four-port 10/100Mbps Ethernet switch
for connecting to PCs on your local network. Data comes into the gateway from the local LAN
and then is "routed" to the remote network, and vice versa. This Gateway provides many
cost-effective functions and management benefits that provides ease of configuration and can be
up and running in few minutes.
DSL/Cable Gateway Applications
Main functions of the DSL/Cable Gateway:
-Share IP Address, provides Internet access to users with one ISP account
-To allow access to the servers from the public network,
-Eliminate the needs of installing software to connect to ISP
-Built in switch provides connectivity to 10/100 Mbps for LAN devices
-Host different services for remote users to access various services at their site using constant IP
-Allow Internal network to be fully exposed to the Internet for special applications (DMZ Host)
-Provides security features that prevents hacking from Internet
Accessing the Internet
The most common use for the DSL/Cable Gateway is to provide Internet access, so that everyone
on your LAN can surf the web and send/receive email or files. The DSL/Cable Gateway
automatically acquires the necessary IP address when the connection to the Internet is
established. You don't need to apply for and assign an IP address to each PC or workstation on
your network.
Accessing Servers from the Public Network
If you want special servers to be accessible by remote users across the Internet (e.g. an e-mail
server, an FTP server, or a web server), you can configure the DSL/Cable Gateway to proxy the
service from its own address. This means that the remote user can address the Gateway as if it
were the special server and the Gateway will redirect this connection to the appropriate computer
on the network.
A Physical Look at the DSL/Cable Gateway
The following illustration shows the rear panel of DSL/Cable Gateway:
(1) 4 RJ-45 10/100 Switch connectors for connecting to PCs and workstations or connecting
external Ethernet hub, or switch with uplink switch on port 4
(2) 1 RJ-45 EWAN connector for connecting to Internet via ADSL/Cable modem
(3) 1 DC power connector for connecting through an AC power adapter (included as part of the
product) to the wall power outlet
(4) Reset button to reset to factory configuration

Setting Up a Windows PC for Configuring the DSL/Cable
Gateway
This section describes how to configure PC on the LAN in order to communicate with the
DSL/Cable Gateway.
The PC need to have an Ethernet interface card installed, and be connected to the DSL/Cable
Gateway either directly (to its LAN ports) or indirectly through an external LAN hub or switch. It
should also have TCP/IP installed, enabled, and configured to obtain an IP address automatically
(i.e., through a DHCP server). If TCP/IP is not already installed, follow the steps below for its
installation.
Note: Any TCP/IP capable workstation can communicate with the DSL/Cable Gateway. To
configure workstations other than Windows 95/98/NT, please consult the manufacturer’s
documentation.
Step 1 Connect your PC to one of the DSL/Cable Gateway Switch ports. If you connect to LAN
3

port 4, you should use a straight LAN cable and set the Uplink switch to the Normal
position or use a crossover LAN cable and set the Uplink switch to Uplink.
Step 2 From the Win95/98 Start button, select Settings, then Control Panel. The Win95/98
Control Panel displays.
Step 3 Double-click on the Network icon.
Step 4 Check your list of Network Components in the Network window Configuration tab. If TCP/IP
has already been installed, go to Step 8. Otherwise, select Add to install it now.
Step 5 In the new Network Component Type window, select Protocol.
Step 6 In the new Select Network Protocol window; select Microsoft in the Manufacturers area.

Step 7 In the Network Protocols area of the same window, select TCP/IP, then click OK. You may
need your Win95/98 CD to complete the installation. After TCP/IP installation is
complete, go back to the Network window shown in Step 4.
Step 8 Select TCP/IP in the list of Network Components.
Step 9 Click on Properties, and check the settings in each of the TCP/IP Properties window:
-Bindings Tab: both Client for Microsoft Networks and File and printer sharing for Microsoft
Networks should be selected.
-Gateway Tab: All fields should be blank
-DNS Configuration Tab: Disable DNS should be selected
-IP Address Tab: Obtain IP address automatically should be selected
Step 10 When the DSL/Cable Gateway is connected to the LAN (and powered on), reboot the PC.
After the PC is re-booted, you should be ready to configure the DSL/Cable Gateway. See
Chapter3.

Connecting more Devices to the DSL/Cable Gateway
The DSL/Cable Gateway provides four LAN ports to allow up to four PCs or Workstations to be
connected to it directly. If you want to connect more devices, you can connect an external hub or
switch to LAN port 4 using a straight LAN cable if the Uplink switch is set to the Uplink position, or
using a cross-over LAN cable if the Uplink switch is set to the Normal position.
Connecting a Hub or Switch to the DSL/Cable Gateway

3 Configuring the DSL/Cable Gateway
Once you have completed the installation stage and have configured a PC properly as described
in chapter two, you are ready to configure the DSL/Cable Gateway for actual applications.
Internet Access in Five Minutes
You can configure your DSL/Cable Gateway quickly by the Setup Wizard at the very first time
when logon to the gateway.
Using Setup Wizard
The Wizard will guide you step by step to configure the gateway for your Internet Access by
connecting DSL/Cable modem.
1. Open your browser and type http://192.168.1.1 in the browser's address box; it is the default
IP address of your Gateway.
2. Logging In
After entering the default IP address as mentioned above, a password prompt screen will ask
you to logon. If you are logging for the first time (by default there is no password, which is blank).
The password is always displayed as a string of asterisks ("*"). Clicking the LOGIN button to
begin gateway management session. If you have modified the password, you’ll have to use
the password that you’ve modified. You need to use the correct password before you can
enter the user interface. No matter what password you use, each character will always be
displayed in the logon prompt as a "*". If you forget the password, you’ll have to reset the
router back to its factory settings.

Select this option to manually input the IP address that your ISP assigned to you. Enter the IP
address, subnet mask, and gateway provided to you by your ISP in the text boxes.
Dial-Up xDSL (PPPoE)
Select this option if your ISP uses PPPoE to connect to their services. Enter the User Name and
Password required by your ISP in the appropriate fields. If some information is not provided to you,
leave it blank. Enter in the Service Name if your ISP uses a Service Name for the PPPoE
Connection, this is optional.
MTU: (Stands for Maximum Transmission Unit) the largest frame size that can be transmitted
over the network. Messages longer than the MTU must be divided into smaller frames.
10

Maximum Idle Time: This represents the number of seconds of inactivity over the connection.
When the timer has expired, the Internet connection will be disconnected.
Note: When you set to 0, the connection will never be time-out.
Auto Reconnect: By checking the Auto-reconnect box, router will automatically connect to ISP
after your system is restarted or once time has expired.
PPTP
Choose this option if your ISP require the PPTP protocol in order for you to connect to the Internet.
Enter the Account Name, Account Password, Host Name, Service IP Address, your IP address,
and your subnet Mask required by your ISP in the appropriate fields. If some information is not

Chapter 4 Advanced Configuration
Advanced Setup
The advanced setup menu is used to configure the LAN and WAN interface, as well as other
advanced functions such as resetting the router, restoring to factory default settings, hosting
services and upgrading to newer version of firmware, client filtering and specials applications.
System Time
The DSL/Cable Gateway maintains a real-time clock, which is automatically set to the local time of
the management PC the first time a connection is made to the interface.
Since the DSL/Cable Gateway does not contain a backup battery for the real-time clock, the time
will not be maintained across system resets or power cycles. Therefore, after a reset or power
cycle, the clock will not be correct. To set the clock once again, simply log on to user interface.
Note that the time zone and daylight savings time indicator are saved across power cycles.
13

Administrator Settings
You can restrict management of the Gateway based on the password. You must enter a
password to gain access to configuration options in the Gateway. There is no password by
default; it is recommended that users assign a password as soon as possible for security reasons.
Time Out period is the amount of time of inactivity before the Gateway will automatically close the
administrative session. When set to 0, it is disabled. You can also manage the Gateway from
the Internet by adding the IP address of an administrator to this screen.
Firmware Update
You can upgrade the firmware (the software that controls the Gateway’s operations). Normally,
this is done when you discover a problem, which is resolved in a different version of firmware that
contains new features that you need. After a message appears telling you that the operation is
completed, you need to reset the system so that the new firmware will take affect.
14

Configuration Tools
Users can use this feature to save gateway’s current configuration and turn it into a file. After
saving this file users can then use the Restore settings to restore to previous settings. You can
also use the restore to factory defaults tool to force the gateway to perform resets and restore to
original factory settings.
