Congratulations on the purchase of your new Barricade. The Barricade provides
shared storage, shared printer usage, and shared Internet access to both Macintosh
and Windows users on your LAN.
Barricade Features
♦Create or Extend your LAN. The built-in 7-port switching hub supports
10BaseT and 100BaseTX to allow connection of any existing devices, while the
10/100BaseT Uplink port provides for connection to another hub.
♦Supports Windows and Macintosh. Clients can be either Microsoft Win-
dows PCs (Windows 95, 98, ME, NT4.0, 2000), or Apple Macintoshes.
♦Built-in Print Server. LAN users - both Windows and Mac - can share the
printer attached to the Barricade, converting it to a "Network Printer".
♦No Client Software. No software needs to be installed on either Windows or
Macintosh clients.
♦File Management using OS tools. Once your PC has access to the Barri-
cade, you can manage your folders and files using the familiar tools provided by
your operating system. For example, Windows users will see the Barricade as
an additional drive in Windows Explorer and My Computer.
♦DHCP Server Support. A DHCP (Dynamic Host Configuration Protocol)
Server provides a dynamic IP address to PCs and other devices upon request.
The requesting devices are called DHCP Clients.
The Barricade can act as either a DHCP Server OR a DHCP Client.
♦Multi Segment LAN Support. If you have a Router, PCs on other LAN
segments can also use the Barricade.
♦Easy Setup. A Quickset Windows program is provided to allow speedy con-
figuration of the Barricade
♦Full Administrator Control over Disk Usage. The LAN Administrator can
control usage of the Barricade's disk storage by the following means:
•Users: To control access to the Barricade, each user has a password
The Administrator can also limit the Disk Storage available to a user.
•Groups: Users are organized into Groups. A user can be in many Groups.
•Shares: A "Share" is a folder (directory) on the Barricade which a User
Group can access. Only the Barricade Administrator can create Shares.
(Users can create folders within the Share.)
•Access Rights: Access to Shares can be Read-Only, Read-Write, or No Ac-
cess. Conveniently, access to Shares is set by Group, not by individual user.
♦Remote Management. The Barricade can be managed from a workstation
anywhere on the LAN, using a WEB browser.


♦Internet Access. The Internet Access feature allows all LAN users to share a
single Internet Account, using either the serial port (for analog modem or ISDN
TA) or the WAN port (for ADSL or Cable modems). The built-in firewall pro-
tects your LAN against external attacks.
♦Advanced Internet Features. The Barricade incorporates a number of ad-
vanced features to add value to your Internet Access:
•Special Applications allows LAN users to use non-standard applications
such as Video-conferencing, Instant Messaging, and other 2-way Internet
applications.
•Virtual Servers allows Internet users to access Web, E-Mail, FTP and
other Servers on your LAN, while still sharing the IP Address provided by
your ISP.
•Filtering functions provide protection for LAN users. You can block high-
risk components such as ActiveX controls. Also, the Site Filter feature al-
lows you to create your own lists of "Allowed" and "Banned" sites. And the
"Log" function can record any attempted accesses which are blocked by the
Site Filter.

Requirements
♦Ethernet Network employing 10BaseT or 100BaseTX.
♦TCP/IP protocol.
LAN Installation
1. Connect Network Devices
♦Use standard LAN cables to connect any existing devices to the Barricade's
LAN (Hub) ports. The Barricade will accept 10BaseT or 100BaseTX, and full
or half duplex. All types may be used simultaneously.
♦If required, use a standard LAN cable to connect the Barricade's "Uplink" port
to a standard port on another Hub. The other Hub can be either 10BaseT or
100BaseT. Note that if using the "Uplink" port, port 7 on the Barricade can
NOT be used.
2. Connect Printer and Modem
♦If you wish to share a printer, use a standard printer cable to connect the printer
to the Barricade's parallel port.
♦If you wish to provide shared Internet access via the Barricade, connect your
modem:
•If using an Analog Modem or ISDN TA, use a standard serial cable to con-
nect your modem to the Barricade's serial port.
•If using an ADSL Modem or Cable modem, connect the modem to the Bar-
ricade's WAN port. Use the cable supplied with your Modem. If no cable
was provided, use a standard LAN cable.
3. Connect Power
♦Connect the supplied power adapter to a power outlet and the Barricade.
♦Press and release the rear-mounted power switch to begin the start-up proce-
dure.
4. Check the boot process
♦During the self-test (2 or 3 seconds), ALL of the LEDs will be ON.
♦During the boot process, the Ready, Error and Disk Full LEDs will be ON.
♦Once the boot process is completed, the Ready LED should be ON and the
Error LED should be OFF. If the Error LED stays On, there is a hardware
problem. Repeated beeps also indicate a failure to boot correctly.

♦For basic operation, only the following setup is required.
♦For the full range of options available to the Network Administrator, refer to
Chapter 3 - Administration.
Software Installation
1. Insert the supplied CD-ROM into the drive of your Windows 95/98/ME or
Windows NT4.0/2000 system.
2. If the Setup program does not start, run SETUP.EXE in the root directory.
3. Click the Barricade Utility button.
4. Follow the prompts to install the Barricade Utility.
Using the Barricade Utility
1. Start the program. Normally, the program will start immediately after installa-
tion. Otherwise, use the Start Menu option created by the installation.
2. The screen will look like the example below. The left section displays a list of
all Barricades. The right section displays data about the currently-selected Bar-
ricade. (If no Barricades are listed, see the Troubleshooting section.)
Figure 2: Barricade Utility
3. Ensure that the desired Barricade is selected in the left panel, then click the
Setup Wizard icon.

Page 9
4. If you are prompted for a User Name and Password, enteradmin for the user
name, and the password you have assigned to the admin user (By default, there
is no password, so the Password field can be left blank.)
5. The Setup Wizard will then start. Step through the Wizard and complete each
screen. The following data will be required:
Server
Server Name: The Default Name is shown. Change this if you wish.
Comment: Comments (e.g. Location of the Barricade) are op-
tional.
Time Zone Select your time zone from the list.
Date/Time Enter the local date (mm/dd/yyyy format) and time.
Microsoft Networking
Workgroup Name: Normally, this name should match the Workgroup
name used by PCs on your LAN.
WINS If your LAN has a WINS (Windows Internet Naming
Service) Server, check the box and enter the IP Ad-
dress of the WINS Server.
TCP/IP
Obtain an IP Address
automatically
(DHCP Client)
If you have a DHCP or Bootp server on your LAN,
you can enable this setting. The Barricade will then
obtain its IP Address from the DHCP or Bootp
server.
However, because this is a Server, it is preferable to
use a Fixed IP Address.
Also, the "DHCP Client" setting will disable
Internet Access via the Barricade.
If your LAN does not have a DHCP server, then you
must select Fixed IP Address.
Fixed IP Address:This option is required if you wish to use the DHCP
Server function. It is also necessary to allow the
Barricade to act as an Internet Gateway, providing
shared Internet access to LAN clients.

IP Address: The current value will be displayed. If this is not
valid for the current location, a warning message will
displayed.
You can enter a new value, or use the "Suggest New
Values" button to get the Wizard to select an unused
value from the Address range used on your LAN.
Network Mask: The must match the value used by PCs on your LAN.
The default Barricade value is 255.255.255.0
Gateway: If you have a Router, enter its IP Address here.
Otherwise, leave this at the default value.
Enable DHCP Server: If checked, the Barricade will provide an IP Address
and related data to PCs on request. PCs will only
make such as request if they are set to act as DHCP
clients. (See Windows Client Setup and Macintosh
Client Setup for details of DHCP Client configura-
tion.)
Start IP Address: The first value for the range of IP Addresses to be
allocated by the DHCP Server.
Finish IP Address: The last value for the range of IP Addresses to be
allocated by the DHCP Server
Ensure that the range is large enough for the number
of DHCP clients (the PCs and other devices making
DHCP requests).
Internet Access
Access Method Select the appropriate setting. If Internet access via
this Server is not required, select None.
Internet Access Setup This screen will vary depending on the Internet
Access method used. This data is available from your
ISP.
6. When the Wizard is complete, the Barricade is operational, with the following
limitations.
•All Windows users will be given "Guest" access rights. This allows Printer
usage, and access to the public folder.
•The advanced Internet-related features (Special Applications, Filtering,
Virtual Servers) are not configured. See Chapter 4 for further details of the
advanced Internet functions.
•Macintosh users can only access Barricade storage with the guest network
logon, or by logging on as admin with no password. (The admin user has
access rights to ALL folders.)

Page 11
•Macintosh users can only access the printer if it is a LaserWriter or com-
patible.
To overcome these limitations
♦Use the Browser-based Administration interface to perform the required Barri-
cade configuration. This is invoked with the Administration icon on the
Barricade Utility's main screen. See Chapter 3 for details on using the Admini-
stration interface.
♦Configure the client PCs as required:
•Details on Client setup for Windows PCs are contained in Chapter 5.
•For Macintosh systems, refer to Chapter 6.
Barricade Setup using Macintosh
If your PC is not running Windows 95/98/ME/NT4/2000, you cannot use the
SETUP program on the CD-ROM.
Instead, you must connect to the Barricade, and configure it, using your Web
Browser. Your Web Browser must support JavaScript V1.1.
The interface has been tested to work on the following Browsers:
♦Netscape Navigator 4.08 or later
♦Internet Explorer 4.0, 5.0, and 5.5
Connecting to the Barricade
1. Ensure your system has a compatible IP Address and Network Mask (Subnet
Mask).
•The Barricade's default values are 192.168.123.254 for the IP Address,
with a Network mask of 255.255.255.0. Your PC should use the same Net-
work Mask, and an IP Address in the range 192.168.123.1 to
192.168.123.253.
•On the Macintosh, you can check using Apple - Control Panel - TCP/IP.
(If this option does not exist, then TCP/IP has not been installed. Use your
Apple system disk to install TCP/IP.)
2. Connect to the Barricade using your Web Browser:
a) Start your Browser
b) In the Address box, enter the following:
HTTP://ip_address
Where ip_address is the IP Address of the Barricade, as in the follow-
ing example:
HTTP://192.168.123.254

Page 12
c) You will be prompted for a name and password.
Enter admin for the name, and leave the password blank. Later, if you set a
password for the admin user, you will be required to enter it here to gain
access to the Barricade.
3. On the first screen, click the Administration button to continue. You will then
see the main menu, as shown below.

•Save your data.
5. Macintosh users can now access the Barricade, provided they use the Guest
button on the Network login, or login as admin.
•As guest, they will have access to the public share. The Barricade Admin-
istrator can grant access to other shares by changing the access rights to the
everyone group.
•The admin user has access rights to ALL folders. By default, the admin
user has no password, but one can and should be assigned.
•Internet Access is not enabled. Use the Web Administration interface to
configure the Barricade for shared Internet Access.
•For further details on using the Web Administration interface, refer to
Chapter 3 - Administration.

Printer Setup
♦If using a LaserWriter, no setup is required. Just perform the client setup proce-
dure in Chapter 5 - Macintosh Client Setup.
♦If not using a LaserWriter, Mac clients must install the printer driver for the
Barricade's printer.
Also, the System - Printer Port screen (below) must be correct. Select "Other"
for Printer connected to Barricade and ensure the Printer Object Type is cor-
rect. Check your printer's documentation to find the Printer Object Type.
Once this is done, the procedure in Chapter 5 - Macintosh Client Setup can be
performed.
Figure 4: System - Printer tab
Setup for Internet Access
See Chapter 4 for details on configuring and using the Internet Access function.

Page 14
Other LAN Devices
If you have a Router, or an existing DHCP Server, it may need to be configured.
Router and/or DHCP Server Configuration is required ONLY if using the
Barricade to provide shared Internet Access.
Note:
If the Barricade is acting as a DHCP Client (rather than a DHCP Server),
than it can NOT provide shared Internet Access.
If the Barricade has a fixed IP Address, it CAN provide shared Internet
Access. So it is possible to use an existing DHCP Server on your LAN,
provided the Barricade is not a DHCP Client.
Router Configuration
♦If your LAN has a Router or Routers, it or they must be configured to pass
Internet packets to the Barricade.
♦Generally, this is done by setting the “Default Route” to be the Barricade. If
necessary, check your Router’s documentation for details of this procedure.
Existing DHCP Server Configuration
If your LAN is using another DHCP Server (rather than the Barricade’s), configure
the DHCP Server to provide the Barricade's IP Address as the Gateway IP Address.

Page 15

Overview
The Barricade administrator can control Barricade usage by creating and managing
Users, Groups, and Shares.
♦Users: Each user is identified by their User Name and Password. The Admin-
istrator can create Users, and also limit the amount of Disk Storage available to
a user.
♦Groups: Users are organized into user Groups. A user can belong to many
Groups.
♦Shares: A "Share" is a folder (directory) on the Barricade which users can ac-
cess. Only the Barricade Administrator can create Shares. However, within a
Share, users who have access to that Share can create other folders (directories)
as well as files.
♦Access Rights: Access to a share can be "Read-only" or "Read-Write". To re-
duce administration workload, access to a Share is granted to a User Group,
rather than to individual users.
Note:
•A Share can be accessed by only 1 Group, but a Group can access many
Shares.
•The admin user, and any other users who are added to the administrator
group, ALWAYS have Read/Write access to ALL shares and folders.
•The guest user has Read/Write access to the public share. This can be
changed, and access to additional shares can be granted, by changing the
access rights for the everyone group.
•Users who do not have a User Name on the Barricade are automatically
given the guest login.
Web Interface
To create and manage users, groups and shares, a Web-style interface is provided.
The Barricade contains a HTTP server. This enables you to connect to it, and con-
figure it, using a Web Browser. The Web Browser must support JavaScript V1.1
The interface has been tested on the following Browsers:
♦Netscape Navigator 4.08 or later
♦Internet Explorer 4.0, 5.0, and 5.5
