can seamlessly connect to the Internet as if you had a permanent connection. This sophisticated, yet easy-to-use device
incorporates the following features.
• Dial-On-Demand. A connection is established to the
Internet as required.
• User-Configurable Bandwidth Utilization. When
using multiple modems or ISDN TAs, users can choose between “Time Saving Mode” (use all bandwidth) or
“Money Saving Mode” (maximize bandwidth utilization).
• Inactivity Time Out. The modem will be disconnected if
no line activity is detected. The time-out period ("Idle
Time") is user-adjustable.
• PPP Authentication. This is used to validate the log-on
to your Internet Service Provider.
• DHCP Server Support. Dynamic Host Configuration
Protocol provides a dynamic IP address to PCs and other
devices upon request.
The Error! Reference source not found. can act as a
DHCP Server.
• Easy Setup. Either a communications program and direct
cable connection; or a WEB browser, can be used.
• Configuration Security Features. Optional password
protection is provided to prevent unauthorized users from
modifying the configuration.
• Hassle-free LAN Installation. An auto-sensing LAN
connection eliminates the need for configuration during
installation in a 10Base2/10BaseT network.
• Multi Segment LAN Support. If you have a Router,
PCs on other LAN segments can use the Error! Refer-
ence source not found. to access the Internet.
Introduction

• Remote Management. The Error! Reference source
not found. can be managed from a workstation anywhere
on the LAN, using a WEB browser.
• E-Mail Gateway. The Error! Reference source not
found. can act as a Gateway for incoming E-Mail, allow-
ing LAN users to share E-Mail accounts. Up to 4 accounts
and 50 users are supported.
• 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 Error! Reference
source not found. 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 Error! Reference source not found.
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 Error! Reference source not
found. 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.

2 Installation
Requirements
• Ethernet Network employing 10BaseT or 10Base2 cable
and the TCP/IP protocol.
• An external modem or ISDN TA (Terminal Adapter).
• Configuration serial cable for Terminal mode configura-
tion (supplied).
• Single user account with a local ISP.
Procedure
The installation choices are as follows.
Configure, then Install
Configuration is done using a serial cable connection and a
VT100 terminal compatible program, before installation. The
only advantage of this method is that you can change the
default IP Address (192.168.0.1) before connection to your
LAN.
Install, then Configure
Here, you connect the Error! Reference source not found. to
your network and then configure it using your WEB Browser.
If the default IP Address (192.168.0.1) is already used by
another device, the other device must be turned OFF until the
Error! Reference source not found. User Guide
10
Error! Reference source not found. is allocated a new IP
Address during configuration.
LAN Installation
Installing your new Error! Reference source not found. in
your existing Ethernet LAN is quick and easy. Simply follow
the instructions below:
1. Choose an Installation Site
Select a place on the network to install the Error! Reference source not found.. Remember that you need phone
jacks and power outlets near your chosen location.
2. Connect Network Cable
The Error! Reference source not found. supports two
types of network cables: Thin Ethernet (10Base2, BNC
connector) and Twisted Pair Ethernet (10BaseT, RJ-45
connector). During power up, the unit automatically detects the type of network cable and adjusts to that
environment.
10Base2 Cabling:
If your network uses 10Base2 cable, insert a BNC “T”
connector into the Error! Reference source not found.’s
BNC port. Connect the cable to one end of the “T”
connector and connect the outgoing cable to the other end.
If the Error! Reference source not found. is at the end of
the network, then cap off the other end of “T” connector
with a 50-ohm terminator. Also, keep in mind that the
maximum effective length between the ends of a 10Base2
network is 185 meters.
Installation
11
10BaseT Cabling:
If your network uses 10BaseT cable, insert one end into
the Error! Reference source not found.’s RJ-45 jack and
the other end into the 10BaseT hub. Keep in mind that the
maximum effective length from the hub to the device is
100 meters.
Warning: Do not attempt to connect more than
one type of cable at the same time or
change the network cable while the
Error! Reference source not found. is
powered On.
3. Connect Modem & Phone Line
Connect the modem, using a standard serial cable, to the
Error! Reference source not found.’s serial port. Next,
connect a telephone line from an RJ-11 style phone jack to
the modem.
4. Connect Power Adapter
Connect the modem’s power adapter to the modem and the
Error! Reference source not found.’s power adapter to
the Error! Reference source not found.. Power both devices On.
Only use the power adapter provided
with your unit. Using a different one
may cause hardware damage.
5. Check the LEDs
When the Error! Reference source not found. is powered On, both LEDs should light, then the Error LED
should go off. If the Error LED stays on, there is a hard-
