Introduction
This Chapter provides an overview of the Internet Gateway’s features and
capabilities.
Congratulations on the purchase of your new Internet Gateway. The Internet Gateway is a
multi-function device providing the following services:
•Shared Broadband Internet Access for all LAN users.
•4-Port Switch for 10BaseT or 100BaseT connections.
Figure 1: Internet Gateway
Internet Gateway Features
The Internet Gateway incorporates many advanced features, which have been carefully de-
signed to provide sophisticated functions, while being easy to use.
Internet Access Features
•Shared Internet Access. All users on the LAN or WLAN can access the Internet
through the Internet Gateway using only a single external IP Address. The local (invalid)
IP Addresses are hidden from external sources. This process is called NAT (Network Ad-
dress Translation).
•DSL & Cable Modem Support. The Internet Gateway has a 10/100BaseT Ethernet
port for connecting a DSL or Cable Modem. All popular DSL and Cable Modems are sup-
ported. SingTel RAS and Big Pond (Australia) login support also is included.
•PPPoE, PPTP, SingTel RAS and Telstra Big Pond Support.The Internet (WAN
port) connection supports PPPoE (Peer-to-Peer Protocol over Ethernet), PPTP (Peer-to-
Peer Tunneling Protocol), SingTel RAS and Telstra Big Pond (Australia), as well as "Di-
rect Connection" type services.
•Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the Internet
Gateway supports both Dynamic IP Address (IP Address is allocated on connection) and
Fixed IP Address.

Advanced Internet Functions
•Communication Applications. Support for Internet communication applications, such
as interactive Games, Telephony, and Conferencing, which are often difficult to use when
behind a Firewall, is included.
•Special Internet Applications. Applications which use non-standard connections or
port numbers are normally blocked by the Firewall. The ability to define and allow such
applications is provided to enable such applications to be used normally.
•Virtual Servers. This feature allows Internet users to access Internet servers on your
LAN. The required setup is quick and easy.
•DMZ. One (1) PC on your local LAN can be configured to allow unrestricted 2-way
communication with Servers or individual users on the Internet. This provides the ability
to run programs which are incompatible with Firewalls.
•URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
•Internet Access Log. See which Internet connections have been made.
•Blocked Packet. Using the Blocked Packet feature, you can assign LAN users to differ-
ent groups, and determine which Internet services are available to each group.
•VPN Pass through Support. PCs with VPN (Virtual Private Networking) software
using PPTP, L2TP and IPSec) are transparently supported; no configuration is required.
LAN Features
•4-Port Switch. The Internet Gateway incorporates a 4-port 10/100BaseT Switch, mak-
ing it easy to create or extend your LAN.
•DHCP Server Support. DHC (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 for devices on your local LAN and WLAN.
•Multi Segment LAN Support. LANs containing one or more segments are supported
via the Internet Gateway’s RIP (Routing Information Protocol) support and built-in static
routing table.
Configuration & Management
•Easy Setup. Use your WEB browser from anywhere on the LAN for configuration.
•Configuration File Upload/Download. Save (download) the configuration data from
the Internet Gateway to your PC, and restore (upload) a previously-saved configuration
file to the Internet Gateway.
•Remote Management. The Internet Gateway can be managed from any PC on your
LAN. And, if the Internet connection exists, it also can (optionally) be configured via the
Internet.
•UPnP Support. UPnP (Universal Plug and Play) allows automatic discovery and
configuration of the Internet Gateway. UPnP is supported by Windows ME, XP, or later.
Security Features
•Password - Protected Configuration. Optional password protection is provided to
prevent unauthorized users from modifying the configuration data and settings.
•NAT Protection. An intrinsic side effect of NAT (Network Address Translation) tech-
nology is that by allowing all LAN users to share a single IP address, the location and the
existence of each PC are hidden. From the external viewpoint, there is no network, only a
single device - - the Internet Gateway.

Introduction

•Stateful Packet Inspection Firewall. All incoming data packets are monitored and all
incoming server requests are filtered, thus protecting your network from malicious attacks
from external sources.
•Protection Against DoS attacks. DoS (Denial of Service) attacks can flood your
Internet connection with invalid packets and connection requests, using so much band-
width and so many resources that Internet access becomes unavailable. The Internet
Gateway incorporates protection against DoS attacks.

Reset Button This button has two (2) functions:
•Reboot. When pressed and released, the Internet Gateway will
reboot (restart).
•Clear All Data. This button also can be used to clear ALL data
and restore ALL settings to the factory default values. Hold in
for 5-7 seconds.
To Clear All Data and restore the factory default values:
1. Power Off.
2. Hold the Reset Button down while you Power On.
3. Keep holding the Reset Button for a few seconds, until the RED
LED has flashed TWICE.
4. Release the Reset Button. The Internet Gateway is now using the
factory default values.
WAN port
(10/100BaseT) Connect the DSL or Cable Modem here. If your modem came with a
cable, use the supplied cable. Otherwise, use a standard LAN cable.
10/100BaseT
LAN connections Use standard LAN cables (RJ45 connectors) to connect your PCs to
these ports.
Note:
Any LAN port on the Internet Gateway will automatically function
as an "Uplink" port when required. Just connect any port to a normal
port on the other hub, using a standard LAN cable.
Power port Connect the supplied power adapter here.

Installation
This Chapter covers the physical installation of the Internet Gateway.
Requirements
•Network cables. Use standard Cat5 or Cat5e cables with RJ45 connectors.
•TCP/IP protocol must be installed on all PCs.
•For Internet Access, an Internet Access account with an ISP, and either of a DSL or Cable
modem (for WAN port usage)
Procedure
Figure 4: Installation Diagram
Installation:
Align the mounting pins with the grid holes on the back of the enclosure. With the mount-
ing pin plungers in the “out” position, press the unit into the grid in the desired location,
then secure by pushing the plungers in.
Cabling the Internet Gateway
The Internet Gateway has four network ports. The ports numbered 1-4 can be used to con-
nect a variety of equipment, including computers, printers, scanners or other network
peripherals. Additionally, the Internet Gateway features a WAN port. The Internet Gate-
way ncan replace an existing hub or switch that has no more than four devices connected,
or that hub/switch can be cascaded with the Internet Gateway (see the instruction sheet for
your hub or switch). Any of the ports numbered 1-4 can be used as an Uplink port.
