Chapter 1
Introduction the ADSL2+ Router
1.1 Introducing the ADSL2+ Router
Welcome to the ADSL2+ Router. Your router is an “all-in-one” unit, combining an ADSL
modem, ADSL router and Ethernet network switch, providing everything you need to get
the machines on your network connected to the Internet over your ADSL broadband
connection.
The router complies with ADSL2+ standards for worldwide deployment and supports
downstream rates of up to 24 Mbps and upstream rates of up to 1 Mbps. It is designed for
small office, home office and residential users, enabling even faster speed Internet
connections. User can enjoy ADSL services and broadband multimedia applications such
as interactive gaming, video streaming and real-time audio much easier and faster than
ever before.
The product supports PPPoA (RFC 2364 –PPP (Point-to-Point Protocol) over ATM
Adaptation Layer 5), RFC 1483 encapsulation over ATM (bridged or routed), PPP over
Ethernet (RFC 2516), and IPoA (RFC1577) to establish a connection with ISP. The product
also supports VC-based and LLC-based multiplexing.
It is the perfect solution to connect a small group of PCs to a high-speed broadband
Internet connection. Multi-users can have high-speed Internet access simultaneously.
This product also serves as an Internet firewall, protecting your network from being
accessed by outside users. Not only provide the natural firewall function (Network Address
Translation, NAT), it also provides rich firewall features to secure user’s network. All
incoming data packets are monitored and filtered. Besides, it can also be configured to
block internal users from accessing to the Internet.
The product provides two levels of security support. First, it masks LAN users’ IP
addresses which are invisible to outside users on the Internet, making it much more difficult

for a hacker to target a machine on your network. Secondly, it can block and redirect
certain ports to limit the services that outside users can access. For example, to ensure
that games and other Internet applications will run properly, user can open some specific
ports for outside users to access internal services in network.
Integrated DHCP (Dynamic Host Control Protocol) services, client and server, allow
multiple users to get their IP addresses automatically on boot up from the product. Simply
set local machines as a DHCP client to accept a dynamically assigned IP address from
DHCP server and reboot. Each time local machine is powered up; the router will recognize
it and assign an IP address to instantly connect it to the LAN.
For advanced users, Virtual Service function allows the product to provide limited visibility
to local machines with specific services for outside users. An ISP (Internet Service
Providers) provided IP address can be set to the product and then specific services can be
rerouted to specific computers on the local network. For instance, a dedicated web server
can be connected to the Internet via the product and then incoming requests for HTML that
are received by the product can be rerouted to the dedicated local web server, even though
the server now has a different IP address. In this example, the product is on the Internet
and vulnerable to attacks, but the server is protected.
Virtual Server can also be used to re-task services to multiple servers. For instance, the
product can be set to allow separated FTP, Web, and Multiplayer game servers to share
the same Internet-visible IP address while still protecting the servers and LAN users from
hackers.

1.2 Features of the ADSL2+ Router
ADSL Multi-Mode Standard
supports downstream rates of up to 24 Mbps and upstream rates of up to 1 Mbps. It also
supports rate management that allows ADSL subscribers to select an Internet access
speed suiting their needs and budgets. It is compliant with Multi-Mode standard (ANSI
T1.413, Issue 2; G.dmt(G.992.1); G.lite(G992.2)), G.hs (G994.1), G.dmt.bis (G.992.3),
G.dmt.bisplus (G.992.5)). The Annex A and B are supported in different H/W platforms.
Fast Ethernet Switch
A 10/100Mbps fast Ethernet switch is built in with automatic switching between MDI and
MDI-X for 10Base-T and 100Base-TX ports. An Ethernet straight or cross-over cable can
be used directly for auto detection.
Multi-Protocol to Establish A Connection
Supports PPPoA (RFC 2364 -PPP over ATM Adaptation Layer 5), RFC 1483
encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516) and IPoA
(RFC1577) to establish a connection with the ISP. The product also supports VC-based
and LLC-based multiplexing.
Quick Installation Wizard
Supports a WEB GUI page to install this device quickly. With this wizard, end users can
enter the information easily which they get from their ISP, then surf the Internet
immediately.
Universal Plug and Play (UPnP) and UPnP NAT Traversal
This protocol is used to enable simple and robust connectivity among stand-alone devices
and PCs from many different vendors. It makes network simple and affordable for users.
UPnP architecture leverages TCP/IP and the Web to enable seamless proximity
networking in addition to control and data transfer among networked devices. With this
feature enabled, users can now connect to Net meeting or MSN Messenger seamlessly.
Network Address Translation (NAT)
Allows multi-users to access outside resources such as the Internet simultaneously with
one IP address/one Internet access account. Many application layer gateway (ALG) are
supported such as web browser, ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping,
NetMeeting, IP phone and others.

Firewall
Supports simple firewall with NAT technologyand provides option for blocking access from
Internet, like Telnet, FTP, TFTP, WEB, SNMP and IGMP.
Domain Name System (DNS) relay
Provides an easy way to map the domain name (a friendly name for users such as
www.yahoo.com) and IP address. When a local machine sets its DNS server with this
router’s IP address, every DNS conversion request packet from the PC to this router will be
forwarded to the real DNS in the outside network.
Dynamic Domain Name System (DDNS)
The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname.
This dynamic IP address is the WAN IP address. For example, to use the service, you must
first apply for an account from a DDNS service like http://www.dyndns.org/.
PPP over Ethernet (PPPoE)
Provides embedded PPPoE client function to establish a connection. Users can get greater
access speed without changing the operation concept, sharing the same ISP account and
paying for one access account. No PPPoE client software is required for local computer.
The Automatic Reconnect and Disconnect Timeout (Idle Timer) functions are provided, too.
Virtual Server
User can specify some services to be visible from outside users. The router can detect
incoming service request and forward it to the specific local computer to handle it. For
example, user can assign a PC in LAN acting as WEB server inside and expose it to the
outside network. Outside user can browse inside web server directly while it is protected by
NAT. A DMZ host setting is also provided to a local computer exposed to the outside
network, Internet.
Users can specify some services to be visible from outside users. The router can detect
incoming service requests and forward either a single port or a range of ports to the
specific local computer to handle it. For example, a user can assign a PC in the LAN acting
as a WEB server inside and expose it to the outside network. Outside users can browse
inside web servers directly while it is protected by NAT. A DMZ host setting is also provided
to a local computer exposed to the outside network, Internet.
Dynamic Host Configuration Protocol (DHCP) client and server
In the WAN site, the DHCP client can get an IP address from the Internet Service Provider
(ISP) automatically. In the LAN site, the DHCP server can allocate a range of client IP

2.5 Cabling
One of the most common causes of problems is bad cabling or ADSL line(s). Make sure
that all connected devices are turned on. On the front of the product is a bank of LEDs.
Verify that the LAN Link and ADSL line LEDs are lit. If they are not, verify that you are using
the proper cables.
Ensure that all other devices connected to the same telephone line as your router (e.g.
telephones, fax machines, analogue modems) have a line filter connected between them
and the wall socket (unless you are using a Central Splitter or Central Filter installed by a
qualified and licensed electrician), and ensure that all line filters are correctly installed and
the right way around. Missing line filters or line filters installed the wrong way around can
cause problems with your ADSL connection, including causing frequent disconnections

Basic Installation
The router can be configured with your web browser. A web browser is included as a
standard application in the following operating systems: Windows 98/NT/2000/XP/Me,
MAC, Linux, etc. The product provides a very easy and user-friendly interface for
configuration.
3.1 Before Configuration
PCs must have an Ethernet interface installed properly and be connected to the router
either directly or through an external repeater hub, and have TCP/IP installed and
configured to obtain an IP address through a DHCP server or a fixed IP address that must
be in the same subnet as the router. The default IP address of the router is 192.168.1.254
and the subnet mask is 255.255.255.0 (i.e. any attached PC must be in the same subnet,
and have an IP address in the range of 192.168.1.1 to 192.168.1.253). The best and
easiest way is to configure the PC to get an IP address automatically from the router using
DHCP. If you encounter any problems accessing the router’s web interface it may also be
advisable to uninstall any kind of software firewall on your PCs, as they can cause
problems accessing the 192.168.1.254 IP address of the router. Users should make their
own decisions on how to best protect their network.
Please follow the steps below for your PC’s network environment installation. First of all,
please check your PC’s network components. The TCP/IP protocol stack and Ethernet
network adapter must be installed. If not, please refer to your Windows-related or other
operating system manuals.
Any TCP/IP capable workstation can be used to communicate with
or through the ADSL2+ Router. To configure other types of
workstations, please consult the manufacturer’s documentation.
