NTRODUCTION
Congratulations on your purchase of the ADSL router. We are proud to
provide you with a powerful yet simple communication device for
connecting your local area network (LAN) to the Internet. For those who
want to surf the Internet in the most secure way, the ADSL router provides
a convenient and powerful solution.
About the ADSL router
The ADSL router provides Internet access to multiple users by sharing a
single-user account. Support is provided for both wired and wireless
devices. New technology provides wireless security via Wired Equivalent
Privacy (WEP) encryption and MAC address filtering. It is simple to
configure and can be up and running in minutes.
Features and Benefits
• Built-in ADSL2/2+ modem - supports download speeds up to
24Mbps
• Local network connection via four 10/100 Mbps Ethernet ports
• Built-in IEEE802.11g 54Mbps Wireless Access Point (AP)
• DHCP for dynamic IP configuration, and DNS for domain name
mapping
I
NTRODUCTION
1-2
• Firewall with Stateful Packet Inspection, client privileges, intrusion
detection, and NAT
• NAT also enables multi-user Internet access via a single user account,
and virtual server functionality (providing protected access to Internet
services such as web, FTP, e-mail, and Telnet)
• VLAN and QoS (Quality of Service) support
• User-definable application sensing tunnel supports applications
requiring multiple connections
• Easy setup through a web browser on any operating system that
supports TCP/IP
Applications
Many advanced networking features are provided by the ADSL router:
• Wireless and Wired LAN
The ADSL router provides connectivity to 10/100 Mbps devices, and
wireless IEEE 802.11g compatible devices, making it easy to create a
network in small offices or homes.
• Internet Access
This device supports Internet access through an ADSL connection.
Since many DSL providers use PPPoE or PPPoA to establish
communications with end users, the ADSL router includes built-in
clients for these protocols, eliminating the need to install these
services on your computer.
A
PPLICATIONS
1-3
• Shared IP Address
The ADSL router provides Internet access for up to 253 users via a
single shared IP address. Using only one ISP account, multiple users
on your network can browse the web at the same time.
• Virtual Server
If you have a fixed IP address, you can set the ADSL router to act as a
virtual host for network address translation. Remote users access
various services at your site using a constant IP address. Then,
depending on the requested service (or port number), the ADSL
router can route the request to the appropriate server (at another
internal IP address). This secures your network from direct attack by
hackers, and provides more flexible management by allowing you to
change internal IP addresses without affecting outside access to your
network.
• DMZ Host Support
Allows a networked computer to be fully exposed to the Internet.
This function is used when NAT and firewall security prevent an
Internet application from functioning correctly.
•Security
The ADSL router supports security features that deny Internet access
to specified users, or filter all requests for specific services that the
administrator does not want to serve. The firewall also blocks
common hacker attacks, including 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. WEP (Wired
Equivalent Privacy), SSID Broadcast disable, and MAC filtering
provide security over the wireless network.

Virtual Server
If you configure the ADSL router as a virtual server, remote users
accessing services such as web or FTP at your local site via public IP
addresses can be automatically redirected to local servers configured with
private IP addresses. In other words, depending on the requested service
(TCP/UDP port number), the ADSL router redirects the external service
request to the appropriate server (located at another internal IP address).
For example, if you set Type/Public Port to TCP/80 (HTTP or web) and
the Private IP/Port to 192.168.2.2/80, then all HTTP requests from
outside users will be transferred to 192.168.2.2 on port 80. Therefore, by
just entering the IP address provided by the ISP, Internet users can access
the service they need at the local address to which you redirect them.
The more common TCP service ports include:
HTTP: 80, FTP: 21, Telnet: 23, and POP3: 110.

RIP
RIP sends routing-update messages at regular intervals and when the
network topology changes. When a router receives a routing update that
includes changes to an entry, it updates its routing table to reflect the new
route. RIP routers maintain only the best route to a destination. After
updating its routing table, the router immediately begins transmitting
routing updates to inform other network routers of the change.
Parameter Description
General RIP Parameters
RIP mode Globally enables or disables RIP.
Auto summary If Auto summary is disabled, then RIP packets will
include sub-network information from all sub-
networks connected to the router.

Authentication Required • None: No authentication.
• Password: A password authentication key is
included in the packet. If this does not match
what is expected, the packet will be discarded.
This method provides very little security as it

watching RIP packets.
• MD5: An algorithm that is used to verify data
integrity through the creation of a 128-bit

Firewall
The ADSL router’s firewall inspects packets at the application layer,
maintains TCP and UDP session information including time-outs and the
number of active sessions, and provides the ability to detect and prevent
certain types of network attacks.
Network attacks that deny access to a network device are called
Denial-of-Service (DoS) attacks. 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 resources.
The ADSL router protects against the following DoS attacks: 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.
(For details see page 4-48.)

•Stateful Packet Inspection
This is called a “stateful” packet inspection because it examines the
contents of the packet to determine the state of the communications; i.e., it
ensures that the stated destination computer has previously requested the
current communication. This is a way of ensuring that all communications
are initiated by the recipient computer and are taking place only with
sources that are known and trusted from previous interactions. In addition
to being more rigorous in their inspection of packets, stateful inspection
firewalls also close off ports until connection to the specific port is
requested.
When particular types of traffic are checked, only the particular type of
traffic initiated from the internal LAN will be allowed. For example, if the
user only checks “FTP Service” in the Stateful Packet Inspection section,
all incoming traffic will be blocked except for FTP connections initiated
from the local LAN.
Stateful Packet Inspection allows you to select different application types
that are using dynamic port numbers. If you wish to use the Stateful Packet
Inspection (SPI) to block 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

• Check connections between the ADSL router,
the external power supply, and the wall outlet.
• If the power indicator does not turn on when the
power cord is plugged in, you may have a
problem with the power outlet, power cord, or
external power supply. However, if the unit
powers off after running for a while, check for
loose power connections, power losses, or
surges at the power outlet.
If you still cannot isolate the problem, then the
external power supply may be defective. In this
case, contact Technical Support for assistance.

LED Indicators
Link LED is Off • Verify that the ADSL router and attached device
are powered on.
• Be sure the cable is plugged into both the ADSL
router and the corresponding device.
• Verify that the proper cable type is used and that
its length does not exceed the specified limits.
• Be sure that the network interface on the
attached device is configured for the proper
communication speed and duplex mode.
• Check the adapter on the attached device and
cable connections for possible defects. Replace
any defective adapter or cable if necessary.
Network Connection Problems
Cannot ping the
ADSL router
from the
attached LAN
• Verify that the IP addresses are properly
configured. For most applications, you should
use the ADSL router’s DHCP function to
dynamically assign IP addresses to hosts on the
attached LAN. However, if you manually
configure IP addresses on the LAN, verify that
the same network address (network component
of the IP address) and subnet mask are used for
both the ADSL router and any attached LAN
devices.
• Be sure the device you want to ping (or from
which you are pinging) has been configured for
TCP/IP.

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.
Specifications
Wiring Conventions
For Ethernet connections, a twisted-pair cable must have two pairs of
wires. Each wire pair is identified by two 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.
