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.
4
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.

DHCP
This Chapter explains the settings on the DHCP Server screen
Overview
A DHCP (Dynamic Host Configuration Protocol) server provides a valid IP address,
Gateway address and DNS addresses to a DHCP client (PC or device) upon request.
The Internet Router can act as a DHCP server. The default value is ON (enabled),
and use of this feature is strongly recommended. Normally, the default values
should not need to be changed.
The PCs must be configured to act a DHCP clients. See page 16 for details of this
procedure.
DHCP Server Screen
This screen can be used to:
< Disable the DHCP server function
< Change the range of IP Address allocated to PCs by the DHCP server.
< Increase the number of DHCP clients which can be accepted. (Default is 50,
maximum is 253).
This screen is reached by the Advanced – DHCP Server hyperlink. An example

Routing
This Chapter explains the Routing features of the Internet Router.
Overview
While the Internet Router includes a standard routing table, this feature can be
completely ignored if you do not have a router in your LAN.
If you DO have a router, it is necessary to configure BOTH the Router and the
Routing table in the Internet Router correctly, as described in the following sections.
See page 42 for an example of configuring both the Internet
Router and the Router.
Internet Router Configuration
An entry in the routing table is required for each LAN segment on your Network,
other than the segment to which this device is attached.
The routing table is accessed by the Routing link on the navigation bar. This link
appears only on the Device Screen
An example Routing screen is shown below.

the fields provided.
Click Add when finished.
Routing Table Data
The data in the Routing Table is as follows.
Destination
IP Address
40
The network address of the remote LAN segment. For
standard class "C" LANs, the network address is the first
3 fields of this Destination IP Address. The 4th (last) field
can be left at 0.
Routing
Network Mask
Gateway
IP Address
Metric
The Network Mask used on the remote LAN segment. For
class "C" networks, the standard Network Mask is
255.255.255.0
The IP Address of the Router on the LAN segment to
which this device is attached. (NOT the router on the
remote LAN segment.)
The number routers which must be navigated to reach the
remote LAN segment. The default value is 1.
Routing tables normally have an "Interface" field. Here, all
entries are for the LAN Interface, so this field is absent.
Router Configuration
It is essential that all IP packets for devices not on the local LAN be passed to the
Internet Router, so that they can be forwarded to the Internet. To achieve this, the
Routers must be configured to use the Internet Router as the Default Route.
Local Router
The local router is the Router installed on the same LAN segment as the Internet
Router. This router Default Route is the Internet Router itself. Typically, routers
have a special entry for the Default Route. It should be configured as follows.
Destination IP Address
Network Mask
Gateway IP Address
Metric
Normally 0.0.0.0, but check your router documentation.
Normally 0.0.0.0, but check your router documentation.
The IP Address of the Internet Router.
1
41
Internet Router User Guide
Other Routers
Other routers must use the Internet Router's Local Router as the Default Route. The
Gateway IP Address will be:
< For routers connected to the Internet Router's local Router, the address of the
Internet Router's local router.
< For routers which must forward packets to another router before reaching the
Internet Router's local router, the Gateway IP Address will be the address of
the intermediate router.

Serial Port
This Chapter explains how to configure the serial (WAN) port on
the Internet Router for Internet Access.
Overview
Currently, the serial (WAN) port can be used only for Internet access, to provide
additional bandwidth.
Either a modem or ISDN TA can be connected to the serial port. The attached
device will be used only when the ISDN link is fully utilized.
To use a Serial port device
To use the serial (WAN) port on the Internet Router for Internet Access:
< Use a standard serial cable to connect the modem or ISDN TA to the serial
(WAN) port on the Internet Router.
< Connect the modem or ISDN TA to the phone line and power outlet.
< Configure the Internet Router's Serial Port Configuration screen with details of
the attached device, and the Internet Account to which it will connect.
< If your ISP uses a non-standard log-in procedure, or your modem/ISDN TA
uses non-standard AT commands, you also need to configure the Advanced
Port screen.

Enter the command (sometimes called the "Dial Prefix
String") your modem requires to precede the phone
number.
Enter the command strings which sets the "Autoanswer" function in your modem or ISDN TA OFF.
The standard AT command is “ATS0=0”
Script File
If your ISP uses a standard PPP connection and authentication, you do NOT need a
script file.
Script files are used to automate the log-in process for ISPs that use non-standard
log-ins or proprietary security measures. For example, if you connect to the Internet
via CompuServe, you DO need a script file.
Script File Commands
Three commands, listed below, can be used within a script file. Note the following
points:
< Items in [ ] are optional, and the [ ] themselves are NOT used.
< Strings must be enclosed in double quotes.
< There must be spaces between commands and parameters (times and strings).
Send [msec] string
Wait msec
Wait [msec] string
50
Send the characters in string, with a. msec (milliseconds) delay between the sending of each character.
Wait for msec milliseconds before executing the next
script line.
Wait for msec milliseconds to receive the string. If the
string is not received within the specified time, the
connection is reset.
If msec is not specified and the string is not received
immediately, an error condition will arise.
Serial Port
Script File Variables
Eleven string variables can be used within the string above. These are used to
include special characters within the string.
Variable Description
\a alert (normally creates a beep)
\b backspace
\f form feed
\n new line
\r carriage return
\t horizontal tab
\v vertical tab
\? Literal question mark
\’ literal single quotation mark
\” literal double quotation mark
\\ literal back slash
< Quote characters are special characters.
< Because each of these variables starts with a backslash, the backslash character
( \ ) is also a special character.
As an example, to send the string "User Name" (including the quotes), the script
file entry should be as follows:
send "\"User Name\""

A - Troubleshooting
Internet Access
Problem 1 Can’t connect to the Internet Router to configure it.
Solution 1 Check the following:
< The Internet Router is properly installed, LAN connec-
tions are OK, and it is powered ON.
< Ensure that your PC and the Internet Router are on the
same network segment. (If you don't have a router, this
must be the case.)
< Ensure that your PC is using an IP Address within the
range 192.168.0.2 to 192.168.0.254 and thus compatible
with the Internet Router's default IP Address of
192.168.0.1.
In Windows, this is done by using Control Panel-
Network to check the Properties for the TCP/IP protocol.
You can also use the “WinIPcfg” program by entering
“WinIPcfg” (without the quotes) in the “Run” dialog box.
Problem 2 When I enter a URL or IP address I get a time out error.
Solution 2 A number of things could cause this. Try the following
troubleshooting steps.
1. If using static IP Addresses, ensure that your worksta-
tions IP settings are correct, including IP address, default
gateway and DNS.
2. Ping the Internet Router. Use the “Run” command to
enter the following command:
Ping xxx.xxx.xxx.xxx
where xxx.xxx.xxx.xxx is the IP address assigned to the
Internet Router.
3. If the ping command fails, check that the Internet Router
is connected and ON. If it is connected and on, there is a
problem with your LAN.
4. Run your Browser and connect to the Internet Router.
5. On the ISDN screen, check that Operation is set to
65
Internet Router User Guide
"Enable".
6. Check the ISDN Status screen, and examine the Con-
nection Log. For details of the Log messages, refer to
Connection Log on page 58.
Problem 3 My Modem/ISDN TA is working fine with a dial-up
connection. How do I find what "Initial String" it is using
before connecting it to the Internet Router serial port?
Solution 3 Use the procedure described in Finding the current Initial
String on page 70.
Problem 4 Some applications do not run properly when using the
Internet Router.
Solution 4 The Internet Router processes the data passing through it, so
it is not transparent. Some programs may have limited
functionality when used with the Internet Router.
The number of supported applications is being expanded as
rapidly as possible. The following applications and protocols
are supported by firmware V5.0:
Telnet, FTP, HTTP, ping
POP/SMTP, Archie, NNTP
TFTP, IRC, Gopher
DNS, SNMP, Real Audio
Printer Sharing
Problem 1 While adding my printer as instructed, I received a
message stating that "The printer could not be found".
Solution 1 Some printer drivers poll the printer to see if it is installed. If
the Printer is installed as a Local Printer, but using the
Internet Router printer port, the printer does not respond and
the “Printer could not be found” message is displayed.
The following Add Printer procedure will overcome this
66
A - Troubleshooting
problem:
1. Select Network printer when asked "How is the printer
attached to your computer?"
2. When prompted for Network Path or Queue name enter
a dummy name such as \\12345 and select Next.
3. The printer wizard will display a message stating "The
Network Printer is off-line". This is OK. Continue to install the printer as normal. Do NOT attempt to print a
test page.
4. When you are finished adding your printer, go to Set-
tings4Printers and select your printer. The printer icon
will be faded out indicating the printer is "off-line" and
unavailable.
5. For Windows 95, select Properties4Details. For Win-
dows NT 4.0, select Ports. Then select print server
(PrintServer) as the port for this printer.
6. Close the Properties window. With the Printer icon still
selected, goto the File menu and ensure Work Off-line is
NOT checked.
7. If the printer is connected properly and powered On, the
printer icon should now be enabled and ready for printing.
Problem 2 I connected and configured a WPS (Windows Printing
System) printer as described, but I can’t get the print job
to print.
Solution 2 When a WPS printer is configured as a Local printer, the
printer driver polls the printer before sending print data.
Since the printer is networked, the printer is not detected and
no data is sent.
Simply add your printer as a network printer as described in
Solution 1 above.
Some popular WPS printers are listed below:
Canon LBP-430W
Epson ActionLaser 1300/W
Epson EPL-5500/W

Windows Peer-to-peer
Overview
This appendix explains how to configure Windows 95/98 to enable a Peer-to-peer
network, using the TCP/IP protocol.
A “Peer-to-peer” network is a network which does not have a dedicated server, but
one or more PCs will allow the other PCs to access their resources (Disk, folders, or
printer).
Procedure
The steps are:
< Install Network cards and drivers
< Install and Configure the TCP/IP protocol.
< Configure Peer-to-peer networking.
Install Network Cards & Drivers
1. Install a Network card (NIC) on each PC. Follow the instructions provided
2. Connect cables from each PC to the hub.
3. Restart each PC, and install the drivers for the Network card. Follow the
4. If you need to change the drivers used by your NIC, follow this procedure:
= Go to Settings-Control Panel-System-Device Manager.
= Click on the "+" sign next to "Network Adapter" to display your NIC. Click on
= Select the Driver Tab.
= Click the "Update Driver" button, and follow the prompts.
with the NIC.
instruction provided with the NIC.
your NIC, then select Properties.
76
C – Windows Peer-to-peer
TCP/IP Installation
1. Navigate to the Network Properties screen. This can be done by either:
= Selecting Start-Settings-Control Panel-Network
= Selecting the Network Neighborhood icon on the desktop, and right-clicking to
select Properties.
2. The "Configuration" tab of the Network Properties screen will appear. An
example screen is shown below.
Figure 32: Network Properties
3. If a line like the one highlighted ("TCP/IP -> NIC”) is not listed, select Add-
Protocol-Microsoft-TCP/IP-OK to add it.
4. Select Properties for the “TCP/IP -> NIC” entry. You will see a screen like the
following.
77
Internet Router User Guide
Figure 33: TCP/IP Properties
5. It is essential for your PC to have an IP Address.
If you click the “Obtain and IP address automatically” button, as shown above,
you need a DHCP (Dynamic Host Configuration Protocol) Server.
The Internet Router can act as a DHCP Server. The DHCP server will provide
all necessary IP information (IP Address, Subnet Mask, Gateway and DNS) to
your PC when it boots.
If you don’t wish to use a DHCP Server, you must give each PC a unique IP
Address, and the same Subnet Mask.
Peer-to-Peer Networking
To enable PCs to communicate with each other:
< On the Identification tab of “Network Properties” (see Figure 32), each PC
needs a unique Computer Name, but the same Workgroup. Only PCs in the
same Workgroup will be visible to your PC.
(You can ignore the Access Control tab. In Peer-to-peer Networks, you must
use “Share Level Access Control”.)
78
C – Windows Peer-to-peer
< Each PC must log-in to the network. The Primary Network Logon (see Figure
32) must be set to Client for Microsoft Networks.
< On boot-up, when the network log-in screen appears, you must log-in, even if
you don’t use a password.
If you press ESC, or click Cancel, no network resources will be available.
To make resources on a PC available to other users:
< On the “Network Properties” screen, (see Figure 32), click the File and Printer
Sharing button, and enable sharing.
You will need to restart your computer for this to take effect.
< In My Computer, select the device (drive, folder, or printer) you wish to share.
Select File-Sharing or Properties-Sharing. (This option is not available if you
have not enabled File and Printer Sharing.)
= Enable sharing.
= Give the resource a name.
= Provide a password if you wish to restrict access.
To gain access to shared resources on other PCs:
< Select the desktop icon Network Neighborhood, and then browse the network
by double-clicking Entire Network. Wait a few seconds, and you will see all
PCs which:
= Are Powered On.
= In the same workgroup.
= Have enabled File and Printer Sharing.
< Double-click on a PC to view the resources it has made available for sharing.
< To gain access to a folder or drive, select it, then select File-Map. Select the
drive letter to use for this resource, and check the Reconnect at Startup option.
You will then be able to access this shared drive or folder using Windows Explorer, or the File-Open/File –Save dialogs in any Windows application.
< To gain access to a shared printer on another PC, right-click on the printer
icon, and select Install.
< If you wish, you can now go to the “Network Properties” screen, (see Figure
32), select Client for Microsoft Networks - Properties and check Quick Log-in.
This will speed the boot process, and avoid error messages if the sharing PC is
not turned on when you boot.
