outgoing packets and letting them pass or halting them based on the IP address of the source
and destination.
Universal Plug and Play (UPnP)
supported
Universal Plug and Play (UPnP) enable devices such as PCs, routers or other devices to be
plugged into a network and automatically know about each other.
Virtual Server supported
Enables you to expose WWW, FTP and other services on your LAN to be accessible to
Internet users.
User-Definable Application Sensing Tunnel

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 on your need, 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
Appendix A 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.
There must be something wrong in your installation procedure. You have to check the following items
in sequence:
1. Is the Ethernet cable correctly connected between this product and your computer?
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.
3.2 Install the Software into Your Computers (Optional)
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.
Step 2: Click on the INSTALL button. Wait until the following We lcome dialog to appear, and click on
the Next button.
Step 3: Select the destination folder and click on the Next button. Then, the setup program will begin to
install the programs into the destination folder.
Step 4: When the following window is displayed, click on the Finish button.
Step 5: Select the item to restart the computer and then click the OK button to reboot your computer.
Step 6: After rebooting your computer, the software installation procedure is finished.
Now, you can configure the NAT Router (refer to Chapter 4) and setup the Print Server (refer to
Chapter 5).
Chapter 4 Configuring NAT Router
This product provides Web based configuration scheme, that is, configuring by your Web browser, such
as Netscape Communicator or Internet Explorer. This approach can be adopted in any MS Windows,
Macintosh or UNIX based platforms.
