1. Introduction
Congratulations on the purchase of your new Internet Gateway.
The Internet Gateway will allow multiple SOHO (Small Office Home Office)
users to share Internet user accounts. It provides a low-cost method of giving
users of your network access to the vast resources available on the Internet.
Once the Internet Gateway is installed and configured, the Internet is
just a click away.

The Internet Gateway is able to use your modem(s) to connect to your
ISP (Internet Service Provider), providing the required log-in information.
You can seamlessly connect to the Internet as if you had a permanent connection.
Alternatively, you can use the Internet Gateway to provide a seamless,
automatic connection to another LAN, provided a matching device is installed on the other LAN.
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 10BaseT or 100BaseT 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. A
static routing table is provided to support multiple routers if needed.
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.
- User-Configurable Bandwidth Utilization. Users can choose
"Time Saving Mode" for maximum performance or "Money Saving Mode" for lower
costs.
LAN-to-LAN Connection
- Direct Dial or Leased Line Support
Connection to the remote LAN can be either through the telephone system
or via a Leased Line (permanent link).
- Seamless Operation
The Internet Gateway can dial the other LAN as required, and
disconnect when no longer required.
- Flexibility
The connection to the remote LAN can use 1 or 2 ports, or 2 ports using multi-link PPP.
If using 1 port, the other port can be used to provide Dial-in access to your LAN.
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 modems and Internet connections can be
monitored from any workstation on the LAN.
Advanced Functions
- Dial-in Remote Access.
Remote users can dial the modem and use the Internet Gateway
to connect to the LAN and access LAN resources.
- LAN-to-LAN Connectivity.
Using 2 Internet Gateways, 2
LANs can be connected via the telephone system. The Internet Gateway will
dial the remote LAN whenever required. Operation is completely automatic and
transparent.
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 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.
