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 in-
stallation 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.

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 view-
point, there is no network, only a single device.
For internal users, the Internet Gateway acts as a “transpar-
ent proxy server”, translating the multiple internal IP
addresses into a single external IP address.
For external requests, any attempt to connect to local re-
sources 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 bar-
rier against malicious attacks.

Introduction
Restore Default IP Address
and Clear Password
If the Internet Gateway's IP Address or password is lost, the
following procedure can be used to recover from this situation.
1. Turn the power to the Internet Gateway OFF.
2. Set the DIP switches to position C.
3. Turn the power to the Internet Gateway ON.
4. Operate the DIP switches in the following sequence (you
have 15 seconds to complete the sequence):
•Set to A
•Set to C
•Set to A
5. The Internet Gateway will now reset, and the Red LED
flash. The following changes will have been made. (Other
configuration data is unchanged.)
•IP Address set to its default value of 192.168.0.1
•Network Mask set to 255.255.255.0
•The password cleared (no password).
6. You can now connect to the Internet Gateway and make
any configuration changes required.
If the DIP switches are simply left at posi-
tion "C", the Internet Gateway will function
normally.
