network from direct attack by hackers, and provides more flexible
management by allowing you to change internal network IP addresses
without affecting outside access to your network.
User-Definable Application Sensing Tunnel
You may define special applications that require multiple connections such
as Internet gaming, video conferencing, and Internet telephony. The BLW-
04EX will then sense the application type and open a multi-port tunnel for
it.

LAN Access
The BLW-04EX provides connectivity to 10/100 Mbps devices, making it
easy to create a network in small offices or homes.
Internet Access
This device supports Internet access through a DSL or cable connection.
Since many DSL providers use PPPoE to establish communications with
end users, the BLW-04EX includes a built-in client for this protocol,
eliminating the need to install this service on your computer.
Shared IP Address
The BLW-04EX shares a single IP address with up to 253 users. Using only
one ISP account, multiple users on your network can simultaneously browse
the Internet.
Virtual Server
If you have a static IP address, you can set up the BLW-04EX to act as a
virtual host for network address translation. Remote users access various
services at your site using the static IP address. Then, depending on the
requested service (or port number), the BLW-04EX routes the request to the
appropriate server (at an internal network IP address). This secures your

1. Connect the LAN: You can connect the BLW-04EX to your PC, or to a
hub or switch. Run Ethernet cable from one of the LAN ports on the rear
of the BLW-04EX to your computer’s network adapter or to another
network device. You can also connect the BLW-04EX to your PC (using
a wireless client adapter) via radio signals. Position both antennas on the
back of the BLW-04EX into the desired positions. For more effective
coverage, you may want to position one antenna along the vertical axis
and the other antenna along the horizontal axis. (The antennas emit
signals along the toroidal plane – and thus provide more effective
coverage when positioned along alternate axes.)
2. Connect the WAN: Prepare an Ethernet cable for connecting the BLW-
04EX to a cable/xDSL modem or Ethernet router.
3. Power on: Connect the power adapter to the BLW-04EX.

2-4. Making LAN Connections
Attach to Your Network Using Radio Signals
Install a wireless network adapter in each computer that will be connected to
the Internet or your local network via radio signals. PCI currently offers
several wireless network cards, including the GW-DS110 Wireless PCI card
and the GW-NS11S Wireless PC card.
Rotate both antennas on the back of the BLW-04EX to the desired position.
For more effective coverage, position one antenna along the vertical axis
and the other along the horizontal axis. Try to place the BLW-04EX in a
position that is located in the center of your wireless network. Normally, the
higher you place the antenna, the better the performance. Ensure that the
BLW-04EX’s location provides optimal reception throughout your home or
office.
Computers equipped with a wireless adapter can communicate with each
other as an independent wireless LAN by configuring each computer to the
same radio channel. However, the BLW-04EX can provide access to your
wired/wireless LAN or to the Internet for all wireless workstations. Each
wireless PC in this network infrastructure can talk to any computer in the
wireless group via a radio link, or access other computers or network
resources inthe wired LAN infrastructure or over the Internetviathe BLW-04EX.
Attach to Your Network Using Ethernet Cabling
The four LAN ports on the BLW-04EX can auto-negotiate the connection
speed to 10 Mbps Ethernet or 100 Mbps Fast Ethernet, as well as the
transmission mode to half-duplex or full-duplex.(See Appendix B for details
on wiring.) Use twisted-pair cable to connect any of the four LAN ports on
the BLW-04EX to an Ethernet adapter on your PC. Otherwise, you can
cascade any of LAN ports on the BLW-04EX to an Ethernet hub or switch,
and then connect your PC or other network equipment to the hub or switch.
When inserting an RJ-45 plug, be sure the tab on the plug clicks into
position to ensure that it is properly seated.
Warning: Do not plug a phone jack connector into any RJ-45 port. This
may damage the BLW-04EX. Instead, use only twisted-pair cables with RJ-
45 connectors that conform with FCC standards.
Notes:
1. Use 100-ohm shielded or unshielded twisted-pair cable with RJ-45
connectors for all connections. Use Category 3, 4 or 5 for connections
that operate at 10 Mbps, and Category 5 for connections that operate at
100 Mbps.
2. Make sure each twisted-pair cable does not exceed 100 meters (328 feet).

BLW-04EX
2-6. Making WAN Connection
Note:
When connecting to the WAN port, use 100-ohm Category 3, 4 or 5
shielded or unshielded twisted-pair cable with RJ-45 connectors at both
ends for all connections.
Connecting the Power Adapter
Plug the power adapter into the power socket on the BLW-04EX, and the
other end into a power outlet. Check the indicator marked Power on the
front panel to be sure it is on. If the Power indicator does not light up, refer
to Troubleshooting in Appendix A.
The wireless infrastructure configuration not only extends the accessibility
of wireless PCs to the wired LAN, but also doubles the effective wireless
transmission range for wireless PCs by retransmitting incoming radio
signals through the BLW-04EX.
A wireless infrastructure can be used for access to a central database, or for
connection between mobile workers, as shown in the following figure:
2-5. Making WLAN Connections
Attach the BLW-04EX to the Internet
If Internet services are provided through an xDSL or cable modem, use
unshielded or shielded twisted-pair Ethernet cable (Category 3 or greater)
with RJ-45 plugs to connect the broadband modem directly to the WAN port
on the BLW-04EX.

BLW-04EX
TCP/IP Configuration
To access the Internet through the BLW-04EX, you must configure the
network settings of the computers on your LAN to use the same IP subnet
as the BLW-04EX. The default network settings for the BLW-04EX are:
IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0
Note:
These settings may be changed to suit your network requirements, but you
must first configure at least one computer as described in Chapter 5 to
access the BLW-04EX’s web configuration interface. (See Chapter 4 for
information on configuring the BLW-04EX.)
If you have not previously configured TCP/IP for your computer, refer to
“Configuring Client TCP/IP” on page 5-1.
All PCs connected to the BLW-04EX must be in the same IP subnet as the
BLW-04EX. The default IP address of the BLW-04EX is 192.168.1.1
(where x means 2–254) and the subnet mask is 255.255.255.0. You can set
the IP address for client PCs either by automatically obtaining an IP address
from the BLW-04EX’s DHCP service or by manual configuration. See
“Setting Up TCP/IP to Work with the BLW-04EX” on page 5-5.
