Applications

Many advanced applications are provided by the BLW-04EX, such as:

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 us e PPPoE to establish communications with

end users, the BLW-04EX includes a built-in client for this proto col,
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

network from direct attack b y 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 BLW­04EX will then sense the application type and open a multi-port tunnel for

it.

DMZ Hosts Support

Allows a networked computer t o be fully exposed to the Internet. This
function is used when th e special application sensing tunnel feature is
insufficient to allow an application to function correctly.

Security

The BLW-04EX supports security features t hat deny Internet access to
specified users, or drop requests for specific services. The B LW- 0 4 E X ’ s

firewall also blocks common hacker attacks, i ncluding IP Spoofing, Land
Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port
loopback, Snork Attack, TCP null scan, and TCP SYN flooding.

Please fill out and return the Warranty Registration Card to PCI, or register
on PCI’s web site at www. p l a n e x . c o m . t w. The BLW-04EX Broadband

Router is covered by a limited lifetime warranty.

Hardware Description

The BLW-04EX Broadband Router may be connected to the Internet or to a
remote site using its RJ-45 WAN port. It may be connected directly to your

PC or to a l ocal area network using any of the four 10/100 autosensing
switch ports.

These RJ-45 ports auto-negotiate the operating speed (10/100 Mbps) and
the duplex mode (half/full duplex).

5

BLW-04EX

BLW-04EX

Access speed to the Intern et depends o n your s ervice type. Full-rate
symmetric Digital Sub scriber Line (ADSL) provid es up to 8 Mbp s

downstream and 640 Kbps upstream; G.lite (or splitterless) ADSL provides
up to 1.5 M bps d ownstream and 512 Kbps upstream; Cable mod ems
provide up to 36 Mbps downstream and 2 Mbps upstream. However, you

should note that the actual rate provided by specific service providers may
vary dramatically from these upper limits.

Though Internet access speed is determined by the modem type connected
to your BLW-04EX, data passing between devices connected to your local
area network can run up to 100 Mbps over the Fast Ethernet ports.

The BLW-04EX includes LED indicators on the front panel that simplify
installation and network troubleshooting.

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 m ore eff e c t i v e

coverage, you may want to position one antenna along the vertical axis
and th

Attach to Your Network Using Ethernet Cabling

The four LAN ports on the BLW-04EX can auto-negotiate the connection
speed to 10 Mb ps Ethernet or 100 Mbp s 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 i nserting an RJ-45 plug, be sure the tab on the plug clicks into
position to ensure that it is properly seated.

Wa r n i n g : 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 RJ­45 connectors that conform with FCC standards.

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 off e r s

several wireless network cards, including the GW-DS110 Wireless PCI card
and the GW-NS11S Wireless PC card.

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).

11

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 compu ters or network
resources in the wired LAN infrastructure or over the Internet via the BLW- 0 4 E X .

12

BLW-04EX

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 l east one computer as described in Chapter 5 to
access the BLW- 0 4 E X ’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
B LW-04EX. The default IP address of the BLW-04EX is 192.1 68.1. 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- 0 4 E X ’s DHCP service or by manual configuration. See

“Setting Up TCP/IP to Work with the BLW-04EX” on page 5-5.

BLW-04EX

Wireless Configuration

To configure the BLW-04EX as a wireless access point for wireless clients
(either stationary or roaming), all you need to do is define the radio channel,

the Service Set identifier (SSID), and encryption options.

You must specify a common radio channel and SSID (Service Set ID) to be
used by t he BLW-04EX and all of your wireless clients. Be sure you

configure all of your clients to the same values.

S S I D : The Service Set ID. This should be set to the same value as other
wireless devices in your network.

Note: The SSID is case sensitive and can consist of up to 32 alphanumeric
characters.

Transmission Rate: Set the data rate transmitted from the BLW-04EX. The
lower the data rate, the longer the t ransmission distance. (Default: Fully

Automatic)

Basic Rate: Select “All (1, 2, 5.5, 11Mbps)” from the drop-down l ist to
optimize the data transfer speed for your network. (Default: 1, 2Mbps)

Channel: The radio channel through which the BLW-04EX communicates
to PCs in its BSS.

(Default: “Auto”)

Note:

The available channel settings are limited to local regulations, which
determine the number of channels that are available.

31

32

BLW-04EX

Encryption

If you are transmitting sensitive data across wireless channels, you should
enable Wired Equivalent Privacy (WEP) encryption.

Encryption requires you to use the same set of encryption/decryption keys
for the BLW-04EX and all of your wireless clients. You can choose between
standard 64-bit or the more robust 128-bit encryption keys.

You can automatically generate encryption keys or you can manually enter
the keys. For automatic 64-bit security, you enter a passphrase that is used

to create four keys (as shown below). The automatic 128 -bit security
generates a single key by entering a passphrase.

BLW-04EX

If you use encryption, configure the same keys used for the BLW-04EX on
each of your wireless clients. Not e that the Wired Equivalent Privacy
(WEP) protects data transmitted between wireless nodes, b ut does not
protect any transmissions over your wired network or over the Internet.

DNS

Domain Name Servers map numerical IP addresses to the equivalent
domain name (e.g., www.planex.com.tw). Your ISP should provide the IP

address of one or more domain name servers. Enter those addresses on this
screen.

Password Settings

Passwords can contain from 3–12 alphanumeric characters and are not case
sensitive.

If your password is lost, or you cannot gain access to the us er interface,
press the Reset button on the rear panel (holding it down for at least five

seconds) to restore the factory defaults (default is “0000”).

Time Zone

Sets the time zone for the BLW-04EX. This information is used for log
entries and client access control.

Use this menu to restrict access based on a password. By default, there is no
password. For security you should assign one before exposing the BLW-

04EX to the Internet.

Address Mapping

Allows one or more public IP addresses to be shared by multiple internal
users. Enter the Public IP address you wish to share into the “Global IP”

field. Enter a range of internal IPs that will share the global IP into the
“from” field.

Virtual Server

If you configure the BLW-04EX as a virtual server, remote users accessing
services such as web or FTP at your local site via public IP addresses can be
au tomaticall y redirected to local servers configu red with private IP

addresses. In other words, depending on the requested service (TCP/UDP
port number), the BLW-04EX redirects the external service request to the
appropriate internal server and port.

BLW-04EX

The WAN interface should have a fixed IP address to properly utilize this
function. For example, if you set Type/Public Port to TCP/80 (HTTP or

web) and the Private IP/Port to 192.168.1.2/8080, then all HTTP requests
from outside users will be transferred to port 80 80 on 192. 168.1. 2.
Therefore, by just entering the IP Address provided by the ISP, Internet

users can access the service you provide at the internal address and port to
which the BLW-04EX redirects them.

Some of the more common TCP service ports include:
HTTP: 80, FTP: 21, Telnet: 23 and POP3: 110.

Security Settings Firewall

The firewall does not significantly affect system performance, so we advise
enabling it to protect your network us ers. Select “Enable” and click the
“APPLY” button to open the Firewall submenus.

The BLW- 0 4 E X ’s firewall can provide the access control of connected
client PCs, block common hacker attacks, including IP Spoofing, Land

Attack, Ping of Death, IP with zero length, Smurf Attack, UDP p ort
loopback, Snork Attack, TCP nul l scan, and TCP SYN flooding. The
firewall does not si gnificantly affect system performance, so we advise

leaving it enabled to protect your network users.

Note:

When y ou select the “Enable” radio button of the “Enable or disable
Firewall module function” field, be sure to press the “APPLY” button.

Intrusion Detection

The Intrusion Detection feature of the BLW-04EX limits the access of the
incoming traffic from the WAN port. When the SPI feature is turned on, all
the incoming packets will be blocked unless certain types of traffic types are

checked by the users. When the user checks certain types of traf fic, only the
particular type of traffic initiated from the Internal LAN will be allowed.
For example, if the user only checks “FTP service” from the Stateful Packet

Inspection heading, all the incoming traffic will be blocked except the FTP
connection initiated from the local LAN.

● Stateful Packet Inspection

This option allows you to select different application types that are using
dynamic port numbers. If you need to use the Stateful Packet Inspection

(SPI) for blocking packets, check the radio button in the “Enable SPI and
Anti-DoS firewall protection” field and then check the inspection type that

you need, such as Packet Fragmentation, TCP Connection, UDP Session,
FTP Service, H.323 Service and TFTP Service.

● Hacker Prevention Feature

The BLW-04EX firewall i nspects packets at the application layer, and
maintains TCP and UDP session information, including timeouts and

number of active sessions, provides the ability to detect and prevent certain
types of network attacks such as DoS attacks.

Network attacks that deny access to a network device are called denial-of­service (DoS) attacks. Denials of Service (DoS) attacks are aimed at devices

and networks with a connection to the Internet. Their goal is not to steal
information, but to disable a device or network so users no l onger have

access to network resource.

By using the above inspected information and timeout/threshold critieria,

the BLW-04EX provides the following DoS attack preventions: Ping of
Death (Ping flood) attack, SYN flood attack, IP fragment attack (Teardrop

Attack), Brute-force attack, Land Attack, IP Spoofing attack, IP with zero
length, TCP null scan (Port Scan Attack), UDP port loopback, Snork Attack

etc.

Note:

The firewall does not significantly affect system performance, so we advise
enabling the prevention features to protect your network users.

●When hackers attempt to enter your network, we can alert you by e-mail

Enter your E-mail address for alerting hacker access. Specify your E-mail
servers, user name and password.

●Connection Policy Enter the appropriate values for TCP/UDP sessions

●DoS Criteria and Port Scan Criteria Setup DoS and port scan criteria in the

spaces provided.

DMZ (Demilitarized Zone)

If you have a client PC that cannot run an Internet application properly from
behind the firewall, then you can open the client up to unrestricted two-way
Internet access. Enter the IP address of a DMZ host to this screen. Adding a

client to the DMZ (Demilitarized Zone) may expose your local network to a
variety of security risks, so only use this option as a last resort.

Step 3. Obtain IP Settings From Your BLW-04EX

Now that you have configured your computer to connect to you r BLW­04EX, it needs to obtain new network settings. By releasing old IP settings

and renewing them with settings from the BLW-04EX, you will also verify
that you have configured your computer correctly.

1. Pull down the Apple Menu. Click “Control Panels” and “TCP/IP.”

2. In the TCP/IP window, your new settings will be shown. Verify that your
IP address is now 192.168.1.xxx, your Subnet Mask is 255.255.255.0 and

your Default Gateway is 192.168.1.1. These values confirm that your
BLW-04EX is functioning.

3. Close the TCP/IP window.

Dynamic IP Allocation via a DHCP Server

Check “Obtain an IP address automatically” on the IP Address tab. Do not
input any values under the Gateway tab, and check “Disable DNS” on the

“DNS Configuration” tab. These settings will be automatically configured
by the DHCP server. Click “OK” and reboot your system to implement the

changes.

Manual IP Configuration

1. Check “Specify an IP address” on the IP Address tab. Enter an IP address
based on the default network 192.168.1.x (where x is between 2 and 254),

and use 255.255.255.0 for the subnet mask.

2. On the “Gateway” tab, add the IP address of the BLW-04EX (default:

192.168.1.1) in the “New gateway” field and click “Add.”

3. On the “DNS Configuration” tab, add the IP address for the BLW-04EX

and click “Add.” This automatically relays DNS requests to t he DNS

server(s) provided by your ISP. Otherwise, add specific DNS servers into

the “DNS Server Search Order” field and click “Add.”

4. After finishing TCP/IP setup, click “OK,” and then reboot the computer.

After that, set up other PCs on the LAN according to the procedures

described above.

Verifying Your TCP/IP Connection

After installing the TCP/IP communication protocols and configuring an IP
address in the same network as the BLW-04EX, use the “Ping” command to

check if your computer has successfully connected to the BLW-04EX. The
following example shows how the Ping procedure can be executed in an

MS-DOS window. First, execute the “Ping” command:

ping 192.168.1.1

If a message similar to the following appears:

Pinging 192.168.1.1 with 32 bytes of data:
Reply from 192.168.1.1: bytes=32 time=2ms TTL=64

a communication link between your computer and the BLW-04EX has been
successfully established.

If you get the following message,

Pinging 192.168.1.1 with 32 bytes of data:
Request timed out.

there may be something wrong in your installation procedure. Check the
following items in sequence:

1. Is the Ethernet cable correctly connected between the BLW-04EX and the
computer?

The LAN LED on the BLW-04EX and the Link LED of the network card
on your computer must be on.

2. Is TCP/IP properly configured on your computer?

If the IP address of the BLW-04EX is 192.168.1.1, the IP address of your
PC m ust be from 192.168.1.2 - 192.168.1.254 and the default gateway
must be 192.168.1.1.

If you can successfully Ping the BLW-04EX you are now read y to
connect to the Internet!

Caution: Do NOT plug a phone jack connector into any RJ-45 port. Use
only twisted-pair cables with RJ-45 connectors that conform with FCC
standards.

For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have
two pairs of wires. Each wire pair is identified by different colors. For
example, one wire might be red and the other, red with white stripes. Also,

an RJ-45 connector must be attached to both ends of the cable.
