Chapter 3 Network Settings and Software Installation
To use this product correctly, you have to properly configure the network settings of your
computers and install the attached setup program into your MS Windows platform
(Windows 95/98/NT/2000).
3.1 Make Correct Network Settings of Your Computer
The default IP address of this product is 192.168.123.254, and the default subnet mask is
255.255.255.0. These addresses can be changed as needed, but the default values are used in
this manual. If the TCP/IP environment of your computer has not yet been configured, you
can refer to AppendixA to configure it. For example,
1. configure IP as 192.168.123.1, subnet mask as 255.255.255.0 and gateway as
192.168.123.254, or more easier,
2. configure your computers to load TCP/IP setting automatically, that is, via DHCP
server of this product.
After installing the TCP/IP communication protocol, you can use the ping command to
check if your computer has successfully connected to this product. The following example
shows the ping procedure for Windows 95 platforms. First, execute the ping command
ping 192.168.123.254
If the following messages appear:
Pinging 192.168.123.254 with 32 bytes of data:
Reply from 192.168.123.254: bytes=32 time=2ms TTL=64
a communication link between your computer and this product has been successfully
established. Otherwise, if you get the following messages,
Pinging 192.168.123.254 with 32 bytes of data:
Request timed out.

-11-
there must be something wrong in your installation procedure. You have to check the
following items in sequence:
1. IstheEthernetcablecorrectlyconnectedbetweenthisproductandyourcomputer?
Tip: The LAN LED of this product and the link LED of network card on your
computer must be lighted.
2. Is the TCP/IP environment of your computers properly configured?
Tip: If the IP address of this product is 192.168.123.254, the IP address of your
computer must be 192.168.123.X and default gateway must be 192.168.123.254.
Now, you can configure the Internet Sharer (refer to Chapter 4).
3.2 Install the Software into Your Computers
Skip this section if you do not want to use the print server function of this product.
Step 1: Insert the installation CD-ROM into the CD-ROM drive. The following window
will be shown automatically. If it isn’t, please run “install.exe” on the CD-ROM.

-12-
Step 2: Click on the INSTALL button. Wait until the following Welcome dialog to appear,

Step 4: When the following window is displayed, click on theFinishbutton.
Step 5: Select the item to restart the computer, then click the OK button to reboot your
computer.
Step 6:After rebooting your computer, the software installation procedure is complete.
Now, you can configure the Internet Sharer (refer to Chapter 4) and set up the Print Server
(refer to Chapter 5).

Chapter 4 Configuring the Barricade
The Barricade provides a Web-based configuration scheme, which is configurable by
Netscape Communicator or Internet Explorer. This approach can be adopted on any MS
Windows, Macintosh or UNIX based platform.
4.1 Startup and Log in
Activate your browser, and disable the proxy or add the IP address of the Barricade into
the exceptions. Then type the Barricade’s IP address in the Location (for Netscape) or
Address (for Explorer) fieldand press ENTER. For example: http://192.168.123.254.
After the connection is established, you will see the web user interface. There are two
appearances of the web user interface: for general users and for system administrator.
To log in as an administrator, enter the system password (the factory setting is ”admin”) in
the System Password field and click the Log inbutton. If the password is correct, the web
appearance will be changed into administrator configure mode. As listed in its main menu,
there are several options for system administration.

-15-
4.2 Status
This option provides the function for observing the product’s operating status:
A. WAN Port Status.
If the WAN port is assigned a dynamic IP, there may appear a “Renew” or
“Release” button on theSidenote column. You can click this button to renew or
release the IP manually.
B. Modem Status.
C. Printer Status. The possible kinds of printer status include “Ready,” “Not ready,”
“Printing… ”, and “Device error.”
When a job is printing, there may appear a “Kill Job” button on the Sidenote
column. You can click this button to kill the current printing job manually.

-16-
4.3 Toolbox
This option enables you to change the administrator password. You can also obtain
information about Firmware version and WAN's MAC Address.
You can also reboot the Barricade by clicking the Reboot button.
The Clone MAC button is useful when your ISP, such as Media One, binds(orlocks) your
connection to a specific MAC address. Please refer to Appendix C.2 for details.
Note: we strongly recommend that you change the system password for security reasons. If
you forget the system password, please refer to Appendix A to reset a new one.

-17-
4.4 Primary Setup
Thisoption enables the product to work properly. The setting items and the web appearance
depend on the type of WAN. Choose the correct WAN.
1. LAN IP Address:The default IP address is 192.168.123.254. You can change it to fit
your needs.
2. WAN Type: WAN connection type of your ISP. You can click Change.. button to
choose a correct one from the following four options:
A. Static IP Address: ISP assigns you a static IP address.
B. Dynamic IP Address: Obtain an IP address from ISP automatically. If you are a
user of @Home service, please refer to Appendix C.1 for the setup procedure.
C. PPP over Ethernet: Some ISPs require the use of PPPoE to connect to their
services.
D. Dial-up Network: To surf the Internet via PSTN/ISDN.

-18-
4.4.1 Static IP Address
WAN IP Address, Subnet Mask, Gateway, Primary and Secondary DNS: enter the proper
setting value provided by your ISP.
4.4.2 Dynamic IP Address
1. Host Name: optional. Required by some ISPs; for example, @Home.
2. Renew IP Forever: this feature enables the Barricade to renew the IP address
automatically when the lease time is expired, even if the system is in an idle state.
4.4.3 PPP over Ethernet
1. PPPoE Account and Password: the account and password that your ISP assigned to
you. If you don't want to change the password, leave it empty.
2. PPPoE Service Name: optional. Input the service name if your ISP requires it.
3. Maximum Idle Time:theelapsedtimeofnoactivitytodisconnectyourPPPoEsession.
Setting it to 0 will disable this feature.
4.4.4 Dial-up Network
1. Dial-up Telephone, Account and Password: assigned by your ISP. If you don't want to
change the password, leave it empty.
2. Primary and Secondary DNS: automatically assigned if they are configured as
"0.0.0.0."
3. Maximum Idle Time:theelapsedtimeofnoactivitytodisconnectyourdial-upsession.
4. Baud Rate: the communication speed between the Barricade and your MODEM or
ISDN TA.
5. Extra Setting: needed to optimize the communication quality between the ISP and
your MODEM or ISDN TA

-19-
4.5 DHCP Server
The settings of the TCP/IP environment include Host IP, Subnet Mask, Gateway, and DNS
configurations. It is not easy to correctly configure all the computers in your LAN
environment. Fortunately, DHCP provides a rather simple approach to handle all these
settings. The Barricade supports the function of DHCP server. If you enable the Barricade’s
DHCP server and configure your computers as “automatic IP allocation” mode, when your
computer is powered on it will automatically load the proper TCP/IP settings from the
Barricade. The settings of DHCP server include the following items:
1. DHCPServer: Choose “Disable” or “Enable.”
2. Range of IP Address Pool: Whenever there is a request, the DHCP server will
automatically allocate an unused IP address from theIP address pool to the requesting
computer. You must specify the starting and ending address of the IP address pool.
3. Domain Name: Optional; this information will be passed to the client. Required by
some ISPs, for example, @Home.
