●User-Definable Application Sensing Tunnel

You may define special applications that require multiple connections such
as Internet gaming, video conferencing, and Internet telephony.

The BRL-04EX will then sense the application type and open a multi-port
tunnel for it.

● DMZ Hosts Support

Allows a networked computer to be fully exposed to the Internet. This
function is u sed when the special application sensing tunnel feature is

insufficient to allow an application to function correctly.

● Security

The BRL-04EX supports security features that deny Internet access to
specified users, or drop requests for specific services. The BRL-04EX'
firewall also blocks common hacker attacks, including IP Spoofing, Land

Attack, Pin g of Death, IP with zero length, Smurf Attack, UDP port
loopback, Snork Attack, TCP null scan, and TCP SYN flooding.

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

●LAN Access

The BRL-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 BRL-04EX includes a built-in client for this protocol,
eliminating the need to install this service on your computer.

● Shared IP Address

The BRL-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 BRL-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 BRL-04EX routes the request to the

appropriate server (at an internal network IP address). This secures your
net work from direct att ack by hackers, an d provides more flexible
management by allowi ng you to change internal network IP addresses
without affecting outside access to your network.

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 BRL-04EX' web configuration interface. (See Chapter 4 for
information on configuring the BRL-04EX.)

If you have not previously configured TCP/IP for your computer, refer to
"Configuring Client TCP/IP" on page 34.

All PCs connected to the BRL-04EX must be in the same IP subnet as the
BRL-04EX. The default IP address of the BRL-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 BRL-04EX' DHCP service or by manual configuration. See "Setting Up
TCP/IP to Work with the BRL-04EX" on page37.

2-3 Making WAN Connections

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.

BRL-04EX

WAN Setting

Select the type of broadband connection you have.

PPP over Ethernet

Some ISPs require the use of PPPoE to connect to their services.

Enter the PPPoE user name and password assigned by your Service
Provider.
The Service Name is normally optional, but may be required by some

service providers.
Enable the Auto-reconnect option to automatically re-establish the
connection as soon as you attempt to access the Internet again.

Enter a Maximum Idle Time (in minutes) to define a maximum period of
time for which the Internet connection is maintained during inactivity. If the
connection is inactive for longer than the Maximum Idle Time, it will be
dropped.

If ISP give you a fixed IP address. You can enable "Fixed IP Address" and
key in "IP Address".

18

Dynamic IP Address

Obtain an IP address automatically.

The Host Name is optional, but may be required by some ISPs. The default
MAC address is set to the WAN's physical interface on the BRL-04EX. Use

this address when registering for Internet service, and do not change it
unless required by your ISP. If your ISP used the MAC address of an
Ethernet card as an identifier when first setting up your broadband account,

connect only the PC with the registered MAC address to the BRL-04EX and
click the "Clone MAC Address" button. This will replace the current BRL­04EX MAC address with the already registered Ethernet card MAC address.
If you are unsure of which PC was origin ally set up by the broadband

technician, call your ISP and request they register a new MAC address for
your account. Register using the default BRL-04EX MAC address.

BRL-04EX

20

BRL-04EX

19

BRL-04EX

You may need a fixed address if you want to provide Internet services, such
as a web server, or FTP server.

Bridge Mode

Use your BRL-04EX as a bridge.

Password Setting

Use this menu to restrict access based on a password. By default, there is
"password". For security you should assign one before exposing the BRL­04EX to the Internet. 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 user 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").

Special Applications

Some applications, such as Internet gaming, videoconferencing, Internet
telephony and others, require multiple connections. These applications
cannot work with Network Address Translation (NAT) enabled. If you need
to run applications that require multiple connections, use the following

screen to specify the additional public ports to be opened for each
application.

PPTP

Point-to-Point Tunneling Protocol (PPTP) allows the secure remote access
over the Internet by simply dialing in a local point provided by an ISP.

Using the above screen allows client PCs to establish a normal PPTP
session and provides hassle-free configuration of the PPTP client on each
client PC.

Static IP Address

ISP assigns you a static IP address.

If your Internet Service Provider has assigned a fixed IP address, enter the
assigned address and subnet mask for the BRL-04EX, then enter the

gateway address of your ISP.
Domain Name Servers map numerical IP addresses to the equival ent
domain name (e.g. , www.planex.n et). Your ISP should provide the IP

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

22

BRL-04EX

21

BRL-04EX

Time Zone Setting

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

Advanced Setting

A detailed setup of the local server function of this product, a virtual
computer (DMZ) function, IP filter ability, etc. is performed.

We highly recommend you keep the default setting.

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 Setting

If you configure the BRL-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 tomatically redirected to local servers configured with private IP

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

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 8080 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 BRL-04EX redirects them.

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

24

BRL-04EX

BRL-04EX

The BRL-04EX Plus' firewall can provide the access control of connected
client PCs, block common hacker attacks, including IP Spoofing, Land

Attack, Pin g of Death, IP with zero length, Smurf Attack, UDP port
loopback, Snork Attack, TCP null scan, and TCP SYN flooding. The
firewall does not significantly affect system performance, so we advise

leaving it enabled to protect your network users.

Note:

When you select the " Enable" radio button of the "En able or disable
Firewall module function" field, be sure press the "ENTER" button.

Access Control

●Hacker Prevention Feature

The BRL-04EX firewall inspects 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-of-service (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 longer

have access to network resource.

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

Intrusion Detection

The Intrusion Detection feature of the BRL-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 checkes certain types of traffic, 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 page, 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, click on the "Yes" 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.
