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 installation 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.
2
Page 6
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.
Page 7
Internet Gateway User Guide
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.

Configuration Program
The Internet Gateway contains a HTTP server. This enables
you to connect to it, and configure it, using your Web Browser.
Most Browsers should work, provided they support HTML
tables and forms.
Preparation
Before attempting to configure the Internet Gateway, please
check the following:
• Since configuration uses the LAN connection, the Internet
Gateway must be installed on your LAN first, and powered
ON.
• If the Internet Gateway's default IP Address (192.168.0.1)
is already used by another device, the other device must be
turned OFF until the Internet Gateway is allocated a new
IP Address during configuration.
Refer to LAN Settings on page 34 for details on assigning a
new IP Address to the Internet Gateway.
12
Page 16
Configuration
Connecting to the Internet Gateway
To establish a connection from your PC to the Internet Gateway:
1. Start your WEB browser
2. In the Address box, enter "HTTP://" and the IP Address of
the Internet Gateway, as in the following example:
HTTP://192.168.0.1
3. You should then see the Home screen. Select the desired
option from the navigation bar.
If you can't connect
If the Internet Gateway does not respond, check the following:
• The Internet Gateway is properly installed, LAN con-
nections are OK, and it is powered ON.
• Ensure that your PC and the Internet Gateway 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 Gateway's default IP Address of
192.168.0.1. Also, check that the Network Mask is set to
255.255.255.0
In Windows, the IP Address and Network Mask can be
checked by using Control Panel-Network to check the
Properties for the TCP/IP protocol.

Internet Access
This Chapter explains how to configure the
Internet Gateway and your LAN for Internet
Access.
Overview
To use the Internet Gateway for Internet Access, the following
operations are required:
• The Internet Gateway's Port screen must be configured
with details of the attached modem or ISDN TA, and the
Internet Account to which the modem or ISDN TA will
connect. Details are in this chapter.
• If you choose not to use the Internet Gateway's default IP
Address, the LAN settings on the Device screen must be
set correctly. Refer to LAN Settings on page 34 for details.
• PC's on the LAN may require configuration, as explained
in this chapter.
• If you have an existing DHCP (Dynamic Host Configura-
tion Protocol) Server, it may require configuration. Details
are in this chapter.
• If you have a router, its address needs to be entered in the
Internet Gateway. Refer to LAN Settings on page 34 for
details.
Also, the router itself needs to be configured to use the
Internet Gateway as its "Default Route" to ensure that
packets are forwarded to the Internet as needed. Check

PC Configuration
Simple LANs
If your PC is NOT using DHCP and your LAN does NOT
contain a router, check the following TCP/IP settings:
• IP Address
• Network Mask
• Gateway IP Address
• DNS (Domain Name Server) Address
IP Address
Ensure that each PC has a unique IP Address from the same
address range as the Internet Gateway's Device IP Address.
For example, if the Internet Gateway uses the default IP Address (192.168.0.1) and Network Mask (255.255.255.0), the
PCs must use addresses from 192.168.0.2 to 192.168.0.254.
Network Mask
All PCs, and the Internet Gateway, must use the same value for
the Network Mask. The default value is 255.255.255.0.
Gateway
Set the PC's Default Gateway Address to the Internet Gateway's IP address (Device IP Address). The default IP Address
for the Internet Gateway is 192.168.0.1.
DNS (Domain Name Server) Address
This must match the DNS address entered into the DNS IP
Address field of the Internet Gateway during configuration.
20
Page 24
Internet Access
If your PC is using DHCP
In this case, no configuration is required. The DHCP server
will provide the following information when your PC (the
DHCP client) boots up:
• IP Address & matching Network Mask
• Gateway IP Address
• DNS (Domain Name Server)
To check if your PC is using DHCP
Under Windows 95, you can check if your PC is acting as a
DHCP client by using the following procedure. For other
operating systems, check your system documentation.
1. Select Control Panel4Network
2. Select the TCP/IP protocol for your network card.
3. Click Properties-IP Address to see the following screen.
Figure 5: IP Address (Win 95)
4. If the radio button for "Obtain an IP address automati-
cally" is checked, as shown above, then your PC is acting
as a DHCP client.
Page 25
Internet Gateway User Guide
DHCP Server Configuration
If you wish to use the DHCP Server in the Internet Gateway,
refer to DHCP Server on page 36. If you already have a DHCP
Server, check the following:
IP Address
The IP Addresses assigned to PCs must be from the same
address range as the Internet Gateway's Device IP Address.
For example, if the Internet Gateway uses the default IP Address (192.168.0.1) and Network Mask (255.255.255.0), the
PCs must use addresses from 192.168.0.2 to 192.168.0.254.
Network Mask
All PCs, and the Internet Gateway, need to be using the same
value for the Network Mask. The default value is
255.255.255.0.
Gateway
This depends on whether your LAN has a router:
• No Router. Set the Default Gateway Address to the IP
address (Device IP Address) assigned to the Internet
Gateway during configuration. The default IP Address is
192.168.0.1.
• Router. Do not change the Default Gateway Address.
Instead, configure the router to use the Internet Gateway as
its "Default Route".
DNS (Domain Name Server) Address
This must match the DNS address entered into the DNS IP
Address field of the Internet Gateway during configuration.
22
Page 26
Internet Access
Router Configuration
If your LAN has a router, you must configure the router so that
it passes all IP packets for devices not on the local LAN to the
Internet Gateway, so that they can be forwarded to the Internet.
This is achieved by configuring the Router so that it uses the
Internet Gateway as its "Default Route".
Check your Router documentation to see how this is done.
Operation - Internet Access
Simply use your Browser as if you had a permanent connection.
If no connection currently exists, there will be a short delay
while the modem connects to your ISP.
Accessing AOL
To access AOL (America On Line) through the Internet Gateway, the following items are necessary :
• Internet account with an ISP.
The details of this account must be entered in the Internet
Gateway like any other Internet Access Account, as explained in this chapter.
• Version 2.5, 3.0 or later of AOL for Windows communica-
tion software.
• The AOL for Windows software must be configured to use
TCP/IP network access, rather than a dial-up connection.
The configuration process is described below.
Page 27
Internet Gateway User Guide
AOL for Windows Configuration
Ensure that the Internet Gateway is configured first, then carry
out the following procedure.
• Start the AOL for Windows communication software.
Ensure that it is Version 2.5, 3.0 or later.
• Click the Setup button.
• Select Create Location, and change the location name
from "New Locality" to "Internet Gateway".
• Click Edit Location. Select TCP/IP for the Network field.

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
(delay times and strings).
Send [msec] string
Wait msec
Wait [msec] string
28
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.
Page 32
Advanced Port Settings
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\""

IP address for the Internet Gateway.
Use the default value of 192.168.0.1 unless:
• The address is already in use.
• Your LAN is using a different IP
address range (not 192.168.0.1 to
192.168.0.254). In this case, use an IP
Address from within the address range
used by your LAN.
If you have a router, enter its IP Address.
Otherwise, leave this at 0.0.0.0.
The default value 255.255.255.0 is standard
for small (class "C") networks.
For other networks, enter the Network Mask
value used by PCs on the same LAN segment as the Internet Gateway.
Page 38
Device Options
If you have a router, it is essential that the router
pass all IP packets for devices not on the local
LAN to the Internet Gateway, so that they can
be forwarded to the Internet.
This is done by configuring the router with the
Internet Gateway as its "Default Route". Check
your Router documentation to see how this is
done.

DHCP Server
A DHCP (Dynamic Host Configuration Protocol) server
provides a valid IP address (and the Gateway and DNS addresses) to a DHCP client (PC or device) upon request. The
Internet Gateway can act as a DHCP server.
To use this feature:
• The Internet Gateway must be configured with the fol-
lowing data.
• The PCs must be configured to act as DHCP clients. This
procedure is explained in the next section.
Configuration Data
Enable/Disable
Start IP Address
Finish IP Address
DNS IP Address
The DNS field will display the DNS entered
in the Port Configuration screen.
36
If Enabled, the Internet Gateway will
function as a DHCP server. The
default value is Disabled.
The IP Start Address and IP Finish
Address fields set the values used by
the DHCP server.
This range also determines the
number of DHCP clients supported.
(Maximum number of clients is 253.)
The IP Addresses provided by your
ISP. Only 1 is essential. Multiple
entries should be entered in the order
you want them accessed. (The first
available DNS will be used.)
Page 40
Device Options
PC Configuration
To use DHCP, you must also configure your PCs to act as
DHCP clients. Client support for DHCP is provided in Win
95’s TCP/IP stack. The procedure for enabling this is detailed
below.
For operating systems other than Win 95, check your system
documentation.
Windows 95 DHCP Client Configuration
1. Select the Control Panel - Network option on the Start
Menu. You should see a screen like the following.
Figure 8: Network Configuration
2. Select the TCP/IP protocol for your network card. Then
click on the Properties button, and the IP Address tab. You
should then see a screen like the following.
Page 41
Internet Gateway User Guide
Figure 9: IP Address (Win 95)
3. Click on the radio button to obtain an IP address automati-
cally, as shown above.
4. Click on the Gateway tab.
The Default Gateway Address should be left blank. The
DHCP server will provide this information.
5. Click on the DNS Configuration tab
The DNS (Domain Name Server) should be “Disabled”.
The DHCP server will provide this information also.
• Information provided by the DHCP Server
will not be visible on this screen. Use the
"Run" dialog to start the WinIPcfg program
to see the addresses allocated by the DHCP
Server.
• To reserve an IP Address for a particular
DHCP client, so that it always receives the
same IP Address, refer to Workstation Data

Access Control
This Chapter explains how to configure and
use the Internet Gateway's "Access Control"
feature.
Overview
The optional Access Control feature allows administrators to:
• Restrict Internet Access by individual workstations.
• Reserve an IP Address for a particular workstation or
network device.
If you DON'T need to reserve IP Addresses or restrict Internet
Access, you can ignore the Access Control screen.
To apply these features to a particular workstation or network
device, you need to know its Network Adapter Address (Hardware Address).
Access Control Screen
The Access Control screen is accessed from the hyperlink on
the Device Settings screen. This screen allows you to:
• Identify individual workstations or devices on the LAN, by
naming them and entering their Network Adapter Address.
• Reserve an IP Address for the workstation or network
device, so that the DHCP Server in the Internet Gateway
always gives them the same IP Address (optional).
39
Page 43

This Chapter the use of the E-Mail Account
Sharing feature of the Internet Gateway.
Overview
The Internet Gateway allows many users to share the E-Mail
Account(s) provided by your ISP. Up to 4 E-Mail accounts and
50 users are supported. The E-mail address is formed by
combining the "User id" and the "Account name", as shown
below. Note that the quotes (" ") and braces ( < > ) ARE
included in the E-mail address.
"user_name"<mail_account@mail_address>
e.g.
"jim"<sales@company.com>
To use this feature:
• Account data must be entered into the Internet Gateway's
E-Mail Account screen for each E-Mail account you wish
to share.
• Data for each user who wishes to share an E-Mail Account
must be entered in the Internet Gateway's Users screen
• A DNS IP Address must be entered either on the Port
Configuration screen or on the Device screen.
• Users must configure their E-Mail program so that their
incoming mail is retrieved through the Internet Gateway,
and that other people know their E-Mail address.
Each of these operations is described in the following section.

Troubleshooting
This Appendix covers the most likely problems
and their solutions.
Overview
This chapter covers some problems that may arise and possible
solutions to them. If you follow the suggested steps and the
Internet Gateway still does not function properly, contact your
dealer for further advice.
Problems
Problem 1 Can’ t connect to the Internet Gateway to
configure it.
Solution 1 Check the following:
• The Internet Gateway is properly
installed, LAN connections are OK, and
it is powered ON.
• Ensure that your PC and the Internet
Gateway 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
63
Page 67
Internet Gateway User Guide
192.168.0.254 and thus compatible with
the Internet Gateway's default IP Address of 192.168.0.1.
In Windows, you can check your PC's
IP Address by using Control PanelNetwork to check the Properties for the
TCP/IP protocol.
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 this is first time you have used your
browser, ensure that your workstations
IP settings are correct, including IP address, default gateway and DNS.
2. Ping the Internet Gateway. 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 Gateway’s LAN
interface.
3. If the ping command fails, check that
the Internet Gateway is connected and
ON. If it is connected and on, there is a
problem with your LAN.
4. Check that Port is "Enabled" (Advanced
Port Settings). If not, you need to use
the HTML program to establish a connection.
5. Run your Browser and connect to the
Internet Gateway.
6. Switch to the Status screen, and exam-

ine the Log. For details of the Log messages, see page 59.
Problem 3: My Modem/ISDN TA is working fine with
a dial-up connection through the serial
port. How do I find what "Initial String"
it is using?
Solution 3 Use the procedure described in Finding the
current Initial String on page 68.
Problem 4 Data Transmissions are very slow.
Solution 4 Check and ensure that the Initial String is
configured to RTS/CTS flow control.
Problem 5 Some applications do not run properly
when using the Internet Gateway.
Solution 5 The Internet Gateway processes the data
passing through it, so it is not transparent.
Some programs may have limited functionality when used with the Internet Gateway.
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

For the Internet Gateway to function correctly, the modem or
ISDN TA must be set as follows.
Setting AT Command
Fixed baud rate setting AT&B1
RTS/CTS flow control AT&K3
DCD to track the presence of a carrier AT&C1
DTR off to hang-up modem AT&D2
DSR always on AT&S0
Modem to return modem-to-modem
data link speed
• For some Mircocom and other modems, the
“ATX4” command is not sufficient - a “W2”
command (no “AT”) must be used as well.
• For an ISDN TA, the above commands may
not be sufficient. Please check the following
section and your ISDN TA's user manual.
ATX4
(see Note below)
For a modem which uses the standard AT commands shown
above, the Initial String would look like the following:
AT&F&B1&K3&C1&D2&S0X4
The first command (AT&F) sets the modem to the factory
defaults, to ensure a consistent starting point.

5. Check the option Record a log file. Then click OK and exit.
6. Use Dial-up Networking to make your on-line connection
normally. A log file MODEMLOG.TXT will be created in
your Windows directory.
7. Use Notepad or another editor to read and print the file
MODEMLOG.TXT.
8. Examine the file to determine the Initial String value.
