Introduction
This Chapter provides an overview of the
Internet Gateway's features and capabilities.
ongratulations on the purchase of your new Internet
Gateway. The Internet Gateway will allow multiple SOHO
(Small Office Home Office) users to share an Internet user
account. It provides a low-cost method of giving LAN users
access to the vast resources available on the Internet.

Once the Internet Gateway is installed and configured, the
Internet is just a click away. You can seamlessly connect to the
Internet as if you had a permanent connection. The Internet
Gateway is able to use your modem to connect to your ISP
(Internet Service Provider) and provide the required log-in
information.

Internet Gateway Features
The Internet Gateway incorporates many advanced features,
carefully designed to provided sophisticated functions while
being easy to use.
LAN Features
• Hassle-free LAN Installation. An auto-sensing LAN
connection eliminates the need for configuration during installation in a 10Base2 or 10BaseT network.
• DHCP Server Support. Dynamic Host Configuration
Protocol provides a dynamic IP address to PCs and other
devices upon request.
The Internet Gateway can act as a DHCP Server.
• Multi Segment LAN Support. If you have a Router,
PCs on other LAN segments can use the Internet Gateway
to access the Internet.
Internet Access Features
• Shared Internet Accounts. All users on the LAN can
share Internet Accounts. You need only 1 account for each
modem, not 1 account for each user.
• Dial-On-Demand & Auto-Disconnect. A connection
is established to the Internet as required, and automatically
disconnected when no longer needed. This reduces on-line
charges to the minimum possible level.
• PPP Authentication. This is used to validate the log-on
to your Internet Service Provider.
Introduction
Configuration & Management
• Easy Setup. Use your WEB browser from anywhere on
the LAN for configuration.
• Remote Management. The Internet Gateway can be
managed from a workstation anywhere on the LAN, using
a WEB browser.
• Remote Monitoring. The modem and Internet connecti-
on can be monitored from any workstation on the LAN.
Advanced Functions
• E-Mail Gateway. The Internet Gateway can act as a
Gateway for incoming E-Mail, allowing LAN users to
share E-Mail accounts. Up to 4 accounts and 50 users are
supported.
• Access Control Features. The LAN Administrator can
limit Internet Access by individual workstations.
Security Features
• Configuration Data. Optional password protection is
provided to prevent unauthorized users from modifying the
configuration.
• Access Control Features. The LAN Administrator can
limit Internet Access by individual workstations.
• Firewall Protection. All incoming data packets are
monitored and all incoming server requests are filtered,
thus protecting your network from malicious attacks from
external sources.
Internet Gateway User Guide

Firewall Protection
The firewall protection provided by the Internet Gateway is
an intrinsic side effect of IP sharing. All users on the LAN
share a single external IP address. From the external viewpoint, there is no network, only a single device.
For internal users, the Internet Gateway acts as a “transparent proxy server”, translating the multiple internal IP
addresses into a single external IP address.
For external requests, any attempt to connect to local resources are blocked. The Internet Gateway will not “reverse
translate” from a global IP address to a local IP address.
This type of “natural” firewall provides an impregnable barrier against malicious attacks.

Configuration Program
The Internet Gateway contains a HTTP server. This enables
you to connect to it, and configure it, using your Web Browser.
Most Browsers should work, provided they support HTML
tables and forms.
Preparation
Before attempting to configure the Internet Gateway, please
check the following:
• Since configuration uses the LAN connection, the Internet
Gateway must be installed on your LAN first, and powered
ON.
• If the Internet Gateway's default IP Address (192.168.0.1)
is already used by another device, the other device must be
turned OFF until the Internet Gateway is allocated a new
IP Address during configuration.
Refer to LAN Settings on page 34 for details on assigning a
new IP Address to the Internet Gateway.
Configuration
Connecting to the Internet Gateway
To establish a connection from your PC to the Internet Gateway:
1. Start your WEB browser
2. In the Address box, enter "HTTP://" and the IP Address of
the Internet Gateway, as in the following example:
HTTP://192.168.0.1
3. You should then see the Home screen. Select the desired
option from the navigation bar.
If you can't connect
If the Internet Gateway does not respond, check the following:
• The Internet Gateway is properly installed, LAN con-
nections are OK, and it is powered ON.
• Ensure that your PC and the Internet Gateway are on the
same network segment. (If you don't have a router, this
must be the case.)
• Ensure that your PC is using an IP Address within the
range 192.168.0.2 to 192.168.0.254 and thus compatible
with the Internet Gateway's default IP Address of
192.168.0.1. Also, check that the Network Mask is set to
255.255.255.0
In Windows, the IP Address and Network Mask can be
checked by using Control Panel-Network to check the
Properties for the TCP/IP protocol.

Chapter 4
Internet Access
This Chapter explains how to configure the
Internet Gateway and your LAN for Internet
Access.
Overview
To use the Internet Gateway for Internet Access, the following
operations are required:
• The Internet Gateway's Port screen must be configured
with details of the attached modem or ISDN TA, and the
Internet Account to which the modem or ISDN TA will
connect. Details are in this chapter.
• If you choose not to use the Internet Gateway's default IP
Address, the LAN settings on the Device screen must be
set correctly. Refer to LAN Settings on page 34 for details.
• PC's on the LAN may require configuration, as explained
in this chapter.
• If you have an existing DHCP (Dynamic Host Configura-
tion Protocol) Server, it may require configuration. Details
are in this chapter.
• If you have a router, its address needs to be entered in the
Internet Gateway. Refer to LAN Settings on page 34 for
details.
Also, the router itself needs to be configured to use the
Internet Gateway as its "Default Route" to ensure that
packets are forwarded to the Internet as needed. Check
your Router's documentation to see how this is done.

PC Configuration
Simple LANs
If your PC is NOT using DHCP and your LAN does NOT
contain a router, check the following TCP/IP settings:
• IP Address
• Network Mask
• Gateway IP Address
• DNS (Domain Name Server) Address
IP Address
Ensure that each PC has a unique IP Address from the same
address range as the Internet Gateway's Device IP Address.
For example, if the Internet Gateway uses the default IP Address (192.168.0.1) and Network Mask (255.255.255.0), the
PCs must use addresses from 192.168.0.2 to 192.168.0.254.
Network Mask
All PCs, and the Internet Gateway, must use the same value for
the Network Mask. The default value is 255.255.255.0.
Gateway
Set the PC's Default Gateway Address to the Internet Gateway's IP address (Device IP Address). The default IP Address
for the Internet Gateway is 192.168.0.1.
DNS (Domain Name Server) Address
This must match the DNS address entered into the DNS IP
Address field of the Internet Gateway during configuration.
Internet Access
If your PC is using DHCP
In this case, no configuration is required. The DHCP server
will provide the following information when your PC (the
DHCP client) boots up:
• IP Address & matching Network Mask
• Gateway IP Address
• DNS (Domain Name Server)
To check if your PC is using DHCP
Under Windows 95, you can check if your PC is acting as a
DHCP client by using the following procedure. For other
operating systems, check your system documentation.
1. Select Control Panel4Network
2. Select the TCP/IP protocol for your network card.
3. Click Properties-IP Address to see the following screen.
