NTRODUCTION

Congratulations on your purchase of the VoIP ADSL Router, hereafter
referred to as the “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, this router provides a convenient and powerful solution. The
Router also enables service providers to provide their residential and small
office home office (SOHO) customers with high-quality VoIP service
using traditional analog telephones and fax machines.

About the Router

The Router provides Internet access to multiple users by sharing a
single-user account. Support is provided for both wired and wireless
devices. This device also provides wireless security via Wired Equivalent
Privacy (WEP), Wi-Fi Protected Access (WPA) and WPA2 encryption, and
MAC address filtering. It is simple to configure and can be up and running
in minutes.

I

NTRODUCTION

Features and Benefits

• Intergrated ADSL modem for connecting to ADSL line

• Local network connection via four 10/100 Mbps Ethernet ports

• On-board IEEE 802.11b/g wireless access point

• DHCP for dynamic IP configuration, and DNS Proxy/Relay for
domain name mapping

• 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, email and Telnet)

• User-definable application sensing tunnel supports applications
requiring multiple connections

• Easy setup through a web browser on any operating system that
supports TCP/IP

• QoS allows you to optimize voice quality by prioritizing VoIP over
data traffic

Applications

Many advanced networking features are provided by the Router:

• Wireless and Wired LAN

The Router provides connectivity to 10/100 Mbps devices, and
wireless IEEE 802.11b/g 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 Router includes built-in clients
for these protocols, eliminating the need to install these services on
your computer.

• Shared IP Address

The 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 access the Internet at the same time.

• Virtual Server

If you have a fixed IP address, you can set the 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 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.

I

NTRODUCTION

1-4

• 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 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 Router’s 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.

• Internet Calling

You can make telephone calls using the Internet.

Virtual Server

If you configure the 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 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

Firewall

The 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 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 4-49.)

Stateful Packet Inspection (SPI) and Anti-DoS firewall protection
(Default: Enabled) — The Intrusion Detection Feature of the Router
limits access for incoming traffic at the WAN port. When the SPI feature
is turned on, all incoming packets will be blocked except for those types
marked in the Stateful Packet Inspection section.

RIP Defect (Default: Enabled) — If an RIP request packet is not
acknowledged to by the Router, it will stay in the input queue and not be
released. Accumulated packets could cause the input queue to fill, causing
severe problems for all protocols. Enabling this feature prevents the
packets from accumulating.

Discard Ping to WAN (Default: Disabled) — Prevent a ping on the
Router’s WAN port from being routed to the network.

• 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
Connection, UDP Session, FTP Service, H.323 Service, or TFTP Service.

ADSL

ADSL (Asymmetric Digital Subscriber Line) is designed to deliver more
bandwidth downstream (from the central office to the customer site) than
upstream. This section is used to configure the ADSL operation type and
shows the ADSL status.

Upstream Maximum upstream data rate.

Downstream Maximum downstream data rate.

Operation Data/Defect Indication

Noise Margin Maximum upstream and downstream noise margin.

Output Power Maximum fluctuation in the output power.

Attenuation Maximum reduction in the strength of the upstream and

downstream signal.

Fast Path FEC
Correction

There are two latency paths that may be used: fast and
interleaved. For either path, a forward error correction
(FEC) scheme is employed to ensure higher data integrity.
For maximum noise immunity, an interleaver may be used
to supplement FEC.

Interleaved Path
FEC Correction

An interleaver is basically a buffer used to introduce a
delay, allowing for additional error correction techniques
to handle noise. Interleaving slows the data flow and may
not be optimal for real-time signals such as video
transmission.

Fast Path CRC Error The number of Fast Path Cyclic Redundancy Check

errors.
