About your Internet
Router
This Chapter provides an overview of the Internet Router's features and capabilities.
ongratulations on the purchase of your new Internet Router. The Internet
Router allows multiple SOHO (Small Office Home Office) users to share a single
Internet user account over an ISDN phone link. It provides the cost-effective
solution of giving users of your network easy access to the vast resources available
on the Internet.
Figure 1: Office to Internet
All of the Internet Router models include a built-in 4 port 10BaseT hub, allowing
you to easily create a peer-to-peer network.
Internet Router INET-830 and INET-850 include two (2) analog a/b ports, allowing
you to connect the analog a/b (POTS) telephone, answering machine, or fax.
For added versatility, the Internet Router INET-830 and INET-850 include a
printer port, allowing LAN users to share the attached printer.

Internet Router User Guide
Internet Router Features
The Internet Router incorporates many advanced features, carefully designed to
provided sophisticated functions while being easy to use.
LAN Features
Ø Built-in Hub. The built-in 4-port hub saves the cost and additional wiring of
a separate hub.
Ø Hassle-free LAN Installation. Just plug it in, whether or not you wish to
use the built-in hub.
Ø DHCP Server Support. Dynamic Host Configuration Protocol provides a
dynamic IP address to PCs and other devices upon request. The Internet
Router can act as a DHCP Server.
Ø Multi Segment LAN Support. If you have a Router, PCs on other LAN
segments can use the Internet Router to access the Internet and, on INET-830
and INET-850, share the printer.
Internet Access Features
Ø Shared Internet Account. All users on the LAN can share the same Internet
Account.
Ø Additional Bandwidth via Serial Port. If the ISDN link is insufficient, you
can connect a modem or ISDN TA to the serial port to provide increased
bandwidth.
Ø 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.
Ø PPP Authentication. This is used to validate the log-on to your Internet
Service Provider.

About your Internet Router
ISDN Features
Ø Easy Configuration. No complex technical data or unintelligible prompts.
You’ll be finished in minutes!
Ø Intelligent B Channel Utilization. Internet access will automatically switch
between 1 or 2 B channels, depending on the data traffic volume.
Ø Outgoing call ID. The Internet Router supports Outgoing call ID for both
MSN (Multiple Subscriber Numbering) and SAD (Sub Address).
Ø Analog Ports. Two (2) analog a/b ports are provided, to allow connection of
your existing analog telephone, answering machine, or fax. (for INET-820
and INET-850)
Ø Analog Call Priority. If both B channels are in use, one channel will be
disconnected when an incoming voice call is detected, or you wish to make an
outgoing voice call. (for INET-820 and INET-850)
Printer Sharing Features (for INET-830 and INET-850)
Ø LAN Printer Sharing. Users on the LAN can share the printer attached to
the Internet Router. All they need to do is install and configure the supplied
software on their PC.
Ø Easy installation & configuration. The "Internet Router Printer Port"
software required for printer sharing installs quickly and requires minimal
configuration.
Configuration & Management
Ø Easy Setup. Use your WEB browser from anywhere on the LAN for configu-
ration.
Ø Remote Management. The Internet Router can be managed, if required,
from a workstation anywhere on the LAN, using a WEB browser.
3
Internet Router User Guide
Ø Remote Monitoring. Internet access via the ISDN link, or serial port usage,
can be monitored from any workstation on the LAN.
Printer status can be checked using the standard Windows printer features.
Security Features
Ø Configuration Data. Optional password protection is provided to prevent
unauthorized users from modifying the configuration.
Ø 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.

About your Internet Router
Firewall Protection
The firewall protection provided by the Internet Router 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 Router 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 Router 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.

Internet Access
This Chapter explains how to install and configure the Internet
Router for Internet Access.
Overview
Setup involves:
< Hardware Installation
< Internet Router configuration
< PC configuration
Software installation is required only for printer sharing. Refer to Chapter 3 –
Printer Sharing for details.
Hardware Installation
1. Connect Network Cables
For each PC, connect one end of a 10BaseT network cable to the Internet
Router’s RJ-45 socket (port1 to 4) and the other end into the RJ45 socket on
the PC. Cable length should not exceed 100 meters (yards).
If connecting the Internet Router to another hub, connect
the "Uplink" port on the Internet Router to a normal port on
the other hub. Note that when the “Uplink” port is in use,
port 4 can NOT be used.
