In most cases, you will not need to configure your device with
these addresses because your ISP is likely to use an Internet
access type which automatically assigns addresses to your
device. For more information, see Types of Internet Access.
Types of Internet Access
The types of Internet access available are as follows:
• PPP Internet access – your device uses a Point to Point
Protocol (PPP) to carry data between your ISP and your
computer. To use PPP Internet access, you must enter a
PPP login username and password the first time to log
on. The IP addresses required to access your ISP’s
Internet service are automatically configured.
Your device supports PPPoE (over Ethernet).
• PPP Internet access – your device uses a Point to Point
Protocol (PPP) to carry data between your ISP and your
computer. To use PPP Internet access, you must enter a
PPP login username and password the first time to log
on. The IP addresses required to access your ISP’s
Internet service are automatically configured.
Your device supports PPPoA (over ATM).
• Bridged Internet access – your device uses a Bridge mode
with your PPPoE Client Software to carry data between
your ISP and your computer. To use Bridged Internet
access with your PPPoE Client Software, you must enter
a PPP login username and password the first time to log
on. The IP addresses required to access your ISP’s
Internet service are automatically configured.
Your device supports RFC 1483 Bridged Mode).
Wireless ADSL2+ Router User’s Guide

Configuring your PPPoE DSL connection
If your ISP’s Internet service uses PPPoE you need to set up a
PPP login account. The first time that you login to the Internet,
your ISP will ask you to enter a username and password so
they can check that you are a legitimate, registered Internet
service user. Your device stores these authentication details, so
you will not have to enter this username and password every
time you login.
Your ISP may also tell you to set unique path and circuit
numbers (called VPI and VCI) in order to connect your device to
the ISP’s Internet service. In most cases, your device will use
default settings, so you may not need to enter these values.
Note
Your ISP will provide you with the login details and VPI/VCI
values necessary to set up a PPP login account.
If your ISP wants you to connect to the Internet using PPP,

MAC ACL is created and distributed to AP so that only
authorized NIC's can connect to the network. While MAC
address spoofing is a proven means to hacking a network this
can be used in conjunction with additional security measures to
increase the level of complexity of the network security
decreasing the chance of a breach.
MAC addresses can be add/delete/edit from the ACL list
depending on the MAC Access Policy.

Fragment
Threshold When transmitting a packet over a network medium,
sometimes the packet is broken into several segments,
if the size of packet exceeds that allowed by the
network medium.
The Fragmentation Threshold defines the number of
bytes used for the fragmentation boundary for directed
messages.
This value should remain at its default setting of 2346.
It specifies the maximum size for a packet before data
is fragmented into multiple packets. If you experience a
high packet error rate, you may slightly increases the
“Fragment Threshold” value within the value range of
256 to 2346. Setting this value too low may result in
poor network performance. Only minor modifications of
this value are recommended.
RTS Threshold This value should remain at its default setting of 2347.
Should you encounter inconsistent data flow, only
minor modifications are recommended. If a network
packet is smaller than the preset “RTS threshold” size,
the RTS/CTS mechanism will not be enabled. The
ADSL modem (or AP) sends Request to Send (RTS)
frames to a particular receiving station and negotiates
the sending of a data frame. After receiving an RTS,
the wireless station responds with a Clear to Send
(CTS) frame to acknowledge the right to begin
transmission.
Beacon Interval The Beacon Interval value indicates the frequency
interval of the beacon. Enter a value between 20 and
1024. A beacon is a packet broadcast by the ADSL
modem (or AP) to synchronize the wireless network.
The default is 100.
Data Rate The rate of data transmission should be set depending
on the speed of your wireless network. You should
select from a range of transmission speeds, or you can
select Auto to have the ADSL modem (or AP)
automatically use the fastest possible data rate and
enable the Auto-Fallback feature. Auto-Fallback will
negotiate the best possible connection speed between
the AP and a wireless client. The default setting is

WPS
Introduction of WPS
Although home Wi-Fi networks have become more and more
popular, users still have trouble with the initial set up of network.
This obstacle forces users to use the open security and
increases the risk of eavesdropping. Therefore, WPS is
designed to ease set up of security-enabled Wi-Fi networks and
subsequently network management (Wi-Fi Protected Setup
Specification 1.0h.pdf, p. 8).
The largest difference between WPS-enabled devices and
legacy devices is that users do not need the knowledge about
SSID, channel and security settings, but they could still surf in a
security-enabled Wi-Fi network. For examples, in the initial
network set up, if users want to use the PIN configuration, the
only thing they need to do is entering the device PIN into
registrar, starting the PIN method on that device and simply wait
until the device joins the network. After the PIN method is
started on both sides, a registration protocol will be initiated
between the registrar and the enrollee. Typically, a registrar
could be an access point or other device that is capable of
managing the network. An enrollee could be an access point or
a station that will join the network. After the registration protocol
has been done, the enrollee will receive SSID and security
settings from the registrar and then join the network. In other
words; if a station attempts to join a network managed by an
access point with built-in internal registrar, users will need to
enter station’s PIN into the web page of that access point. If the
device PIN is correct and valid and users start PIN on station,
the access point and the station will automatically exchange the
encrypted information of the network settings under the
management of AP’s internal registrar. The station then uses
this information to perform authentication algorithm, join the
secure network, and transmit data with the encryption algorithm.
More details will be demonstrated in the following sections.
Supported WPS features
Currently, Wireless Gateway supports WPS features for AP
mode, AP+WDS mode, Infrastructure-Client mode, and the
wireless root interface of Universal Repeater mode.
Other modes such as WDS mode, Infrastructure-Adhoc
mode, and the wireless virtual interface of Universal
Repeater mode are not implemented with WPS features.
If those unsupported modes are enforced by users, WPS
will be disabled. Under the configuration of every WPS-
supported mode, Wireless Gateway has Push Button method
and PIN method. For each method, Wireless Gateway offers
different security levels included in network credential, such as
open security, WEP 64 bits, WEP 128 bits, WPA2-Personal
TKIP, and WPA2-Personal AES. Users could choose either one
of the methods at their convenience.
User’s Guide Configuring your Computers
104
AP mode
For AP mode, Wireless Gateway supports three roles, registrar,
proxy, and enrollee in registration protocol. At different
scenarios, Wireless Gateway will automatically switch to an
appropriate role depending on the other device’s role or a
specific configuration.
AP as Enrollee
If users know AP’s PIN and enter it into external registrar, the
external registrar will configure AP with a new wireless profile
such as new SSID and new security settings. The external
registrar does this job either utilizing the in-band EAP (wireless)
or out-of-band UPnP (Ethernet). During the WPS handshake, a
wireless profile is encrypted and transmitted to AP. If the
handshake is successfully done, AP will be re-initialized with the
new wireless profile and wait for legacy stations or WPS
stations to join its network.
AP as Registrar
Wireless Gateway also has a built-in internal registrar.
Whenever users enter station’s PIN into AP’s webpage, click
“Start PBC”, or push the physical button, AP will switch to
registrar automatically. If users apply the same method on
station side and the WPS handshake is successfully done,
SSID and security settings will be transmitted to that station
without the risk of eavesdropping. And then the station will
associate with AP in a security-enabled network.
AP as Proxy
At this state, AP is transparent to users. If users want to
configure a station or any device that is capable of being an
enrollee, they have to enter device’s PIN into an external
registrar and choose an appropriate wireless profile. After the
PIN is entered, the external registrar will inform AP this event.
AP then conveys the encrypted wireless profile between the
device and the external registrar. Finally, the device will use the
wireless profile and associate with AP. However, the device
may connect to other APs if the wireless profile does not belong
to the proxy AP. Users must carefully choose the wireless
profile or create a wireless profile on an external registrar.
Infrastructure-Client mode
In Infrastructure-Client mode, Wireless Gateway only supports
enrollee’s role. If users click “Start PIN”, click “Start PBC”, or
press the physical button on Wireless Gateway, it will start to
seek WPS AP. Once users apply the same method on registrar
side, Wireless Gateway will receive the wireless profile upon
successfully doing the registration protocol. Then Wireless
Gateway will associate with an AP.
User’s Guide Configuring your Computers
105
Instructions of AP’s and Client’s operations
At this state, AP is transparent to users. If users want to
configure a station or any device that is capable of being an
enrollee, they have to enter device’s PIN into an external
registrar and choose an appropriate wireless profile. After the
PIN is entered, the external registrar will inform AP this event.
AP then conveys the encrypted wireless profile between the
device and the external registrar. Finally, the device will use the
wireless profile and associate with AP. However, the device
may connect to other APs if the wireless profile does not belong
to the proxy AP. Users must carefully choose the wireless
profile or create a wireless profile on an external registrar.

15 Routing
The Routing page enables you to define specific route for your
Internet and network data.
Most users do not need to define routes. On a typical small
home or office LAN, the existing routes that set up the default
gateways for your LAN hosts and for the DSL device provide
the most appropriate path for all your Internet traffic.
−On your LAN hosts, a default gateway directs all Internet traffic
to the LAN port(s) on the DSL device. Your LAN hosts know
their default gateway either because you assigned it to them
when you modified your TCP/IP properties, or because you
configured them to receive the information dynamically from a
server whenever they access the Internet.
−On the DSL device itself, a default gateway is defined to direct
all outbound Internet traffic to a route at your ISP. The default
gateway is assigned either automatically by your ISP whenever
the device negotiates an Internet access, or manually by user to
setup through the configuration.
You may need to define routes if your home setup includes two
or more networks or subnets, if you connect to two or more ISP
services, or if you connect to a remote corporate LAN.

RIP
RIP is an Internet protocol you can set up to share routing table
information with other routing devices on your LAN, at your
ISP’s location, or on remote networks connected to your
network via the ADSL line.
Most small home or office networks do not need to use RIP;
they have only one Router,such as the ADSL Router, and one
path to an ISP. In these cases, there is no need to share routes,
because all Internet data from the network is sent to the same
ISP gateway.
You may want to configure RIP if any of the following
circumstances apply to your network:
−Your home network setup includes an additional Router or
RIP-enabled PC (other than the ADSL Router). The ADSL
Router and the Router will need to communicate via RIP to
share their routing tables.
−Your network connects via the ADSL line to a remote network,
such as a corporate network. In order for your LAN to learn the
routes used within your corporate network, they should both be
configured with RIP.
−Your ISP requests that you run RIP for communication with
devices on their network.

16 DMZ
A demilitarized zone (DMZ) is a host or small network that acts
as neutral ground between the inside and outside network. It
contains information that is useful to users of both the inside
and outside network. For example, a company may wish to
provide software patches to customers via an FTP server.
However, it does not want FTP access to any hosts other than
the FTP server. This is achieved by creating a DMZ network
which is less restrictive than the internal network.Users attached
to the outside network can access the DMZ, but they cannot
access any other company data.

17 Virtual Server
Your device has built in advanced Security features that protect
your network by blocking unwanted traffic from the Internet.
If you simply want to connect from your local network to the
Internet, you do not need to make any changes to the default
Security configuration. You only need to edit the configuration if
you wish to do one or both of the following:
• allow Internet users to browse the user pages on your local
network (for example, by providing an FTP or HTTP server)
• play certain games which require accessibility from the
Internet
This chapter describes how to configure Security to suit the
needs of your network.
By default, the IP addresses of your LAN PCs are hidden from
the Internet. All data sent from your LAN PCs to a PC on the
Internet appears to come from the IP address of your device.
In this way, details about your LAN PCs remain private. This
security feature is called Port Forwarding.
Configuring Virtual Server
Certain network games, chat or file sharing software do not

32 UPnP
UPnP is an architecture for pervasive peer-to-peer network
connectivity of intelligent appliances, Wireless devices, and PCs
of all form factors. It is designed to bring easy-to-use, flexible,
standards-based connectivity to ad-hoc or unmanaged
networks whether in the home, in a small business, public
spaces, or attached to the Internet. UPnP is a distributed, open
networking architecture that leverages TCP/IP and the Web
technologies to enable seamless proximity networking in
addition to control and data transfer among networked devices
in the home, office, and public spaces.
UPnP is more than just a simple extension of the plug and play
peripheral model. It is designed to support zero-configuration,
"invisible" networking, and automatic discovery for a breadth of
device categories from a wide range of vendors. This means a
device can dynamically join a network, obtain an IP address,
convey its capabilities, and learn about the presence and
capabilities of other devices. DHCP and DNS servers are
optional and are used only if available on the network. Finally, a
device can leave a network smoothly and automatically without
leaving any unwanted state behind.
The DSL device supports a control point for Universal Plug and
Play (UPnP) version 1.0, and supports two key features: NAT
Traversal and Device Identification. This feature requires one
active WAN interface. In addition, the host should support this
feature. In the presence of multiple WAN interfaces, select an
interface on which the incoming traffic is present.
With NAT Traversal, when an UPnP command is received to
open ports in NAT, the application translates the request into
system commands to open the ports in NAT and the firewall.
The interface to open the ports on is given to UPnP when it
starts up and is part of the configuration of the application.
For Device Identification, the application will send a description
of the DSL device as a control point back to the host making the
request.

35 Dynamic DNS Configuration
Overview of Dynamic DNS
If some host has a dynamic IP address that keeps changing
frequently, it is difficult to keep updating the IP record that is
associated with the domain name of this host in the zone files.
This will result in non-accessibility of this host on the Internet.
Dynamic DNS service allows to keep mapping of a dynamic IP
address of such host to a static hostname. Dynamic DNS
services are provided by many websites. The host needs to
register with some website and get a domain name. When the
IP address of the host changes, it just needs to send a message
to the website that's providing dynamic DNS service to this host.
For this to work, an automated update client needs to be
implemented. These update clients send update messages to
the servers whenever there is some change in the IP address of
that host. Then, the server updates the entries for that host and
replies back with some return code.
Above Figure explains one such scenario in which a host gets a
dynamic IP address for itself from a DHCP server. As the host
has registered with one of the dynamic DNS service providers
on the Internet, it sends an update message to the service
provider with host name and changed IP address. The service
provider updates the new IP address of the host in the zone
files that have entry for that host name and replies back with
some return code. The return code communicates the success
or failure of the update message. This process is repeated
every time the host's IP address changes.
If the dynamic DNS service provider is notified of the same IP
address again and again, then it considers it an abuse and
might block the host name. To avoid this scenario, the IP
address that was successfully updated to the ISP is stored on
the unit. Whenever we receive an IP address change
notification, the new IP address is compared with the IP address
that was stored on the last update. If they differ, then only an
User’s Guide Configuring your Computers

update request is sent. However, when the system comes up
there is no way of knowing what was the IP address on last
successful update before the system went down. You need to
give the command “system config save“ periodically to save this
IP address on Flash.
Registering With Dynamic DNS Service Provider
Currently, Wireless ADSL2+ Router supports two Dynamic DNS
service providers, www.tzo.com and www.dyndns.com. To use
their Dynamic DNS service, you first need to visit the Web site
of a service provider and register. While registering, you need to
provide your username, password, and hostname as mandatory
parameters. A service provider may also prompt you to fill some
optional parameters.
Configuring IP Interfaces
You need to create a Dynamic DNS interface per IP interface
and can only create one Dynamic DNS interface service on one
IP interface. For more information on creating IP interfaces,
refer to section Creating IP interfaces.
Note
www.dyndns.org provides three kinds of services - Dynamic DNS,
Custom DNS and Static DNS. You can create different domains in
these systems. Custom DNS service is a full DNS solution for
newly purchased domains or domains you already own. A web-
based interface provides complete control over resource records
and your entire domain, including support for dynamic IPs and
automated updates. Static DNS service points a DNS hostname
in some domain owned by dyndns.org to the user's ISP-assigned
static or pseudo-static IP address.
DynDNS service points a fixed hostname in some domain owned
by dyndns.org to the user's ISP-assigned dynamic IP address.
This allows more frequent update of IP addresses, than allowed
by Static DNS.

−F4: used in VPs
−F5: used in VCs
An ATM connection consists of a group of points. This OAM
implementation provides management for the following points:
−Connection endpoint: the end of a VP/VC connection where
the ATM cell are terminated
−Segment endpoint: the end of a connection segment

A Configuring your Computers
This appendix provides instructions for configuring the Internet
settings on your computers to work with the Wireless ADSL2+
Router.
Configuring Ethernet PCs
Before you begin
By default, the Wireless ADSL2+ Router automatically assigns
the required Internet settings to your PCs. You need to
configure the PCs to accept this information when it is assigned.
Note
In some cases, you may want to assign Internet information
manually to some or all of your computers rather than allow the
Wireless ADSL2+ Router to do so. See Assigning static Internet
information to your PCs for instructions.

Assigning static Internet information to your PCs
If you are a typical user, you will not need to assign static
Internet information to your LAN PCs because your ISP
automatically assigns this information for you.
In some cases however, you may want to assign Internet
information to some or all of your PCs directly (often called
“statically”), rather than allowing the Wireless ADSL2+ Router to
assign it. This option may be desirable (but not required) if:
• You have obtained one or more public IP addresses that
you want to always associate with specific computers (for
example, if you are using a computer as a public web
server).
• You maintain different subnets on your LAN (subnets are
described in Appendix B).
Before you begin, you must have the following information
available:
• The IP address and subnet mask of each PC
• The IP address of the default gateway for your LAN. In
most cases, this is the address assigned to the LAN port on
the Wireless ADSL2+ Router. By default, the LAN port is
assigned the IP address 192.168.1.1. (You can change this
number or another number can be assigned by your ISP.
See Addressing for more information.)
• The IP address of your ISP’s Domain Name System (DNS)
server.
On each PC to which you want to assign static information,
follow the instructions relating only to checking for and/or
installing the IP protocol. Once it is installed, continue to follow
the instructions for displaying each of the Internet Protocol
(TCP/IP) properties. Instead of enabling dynamic assignment of
the IP addresses for the computer, DNS server and default
gateway, click the radio buttons that enable you to enter the
information manually.
Note
Your PCs must have IP addresses that place them in the same
subnet as the Wireless ADSL2+ Router’s LAN port. If you manually
assign IP information to all your LAN PCs, you can follow the
instructions in Addressing to change the LAN port IP address
accordingly.

B IP Addresses, Network Masks, and
Subnets
IP Addresses
Note
This section refers only to IP addresses for IPv4 (version 4 of the
Internet Protocol). IPv6 addresses are not covered.
This section assumes basic knowledge of binary numbers, bits,
and bytes.
IP addresses, the Internet's version of telephone numbers, are
used to identify individual nodes (computers or devices) on the
Internet. Every IP address contains four numbers, each from 0
to 255 and separated by dots (periods), e.g. 20.56.0.211. These
numbers are called, from left to right, field1, field2, field3, and
field4.
This style of writing IP addresses as decimal numbers
separated by dots is called dotted decimal notation. The IP
address 20.56.0.211 is read "twenty dot fifty-six dot zero dot
two-eleven."
Structure of an IP address
IP addresses have a hierarchical design similar to that of
telephone numbers. For example, a 7-digit telephone number
starts with a 3-digit prefix that identifies a group of thousands of
telephone lines, and ends with four digits that identify one
specific line in that group.
Similarly, IP addresses contain two kinds of information:
• Network ID
Identifies a particular network within the Internet or intranet
• Host ID
Identifies a particular computer or device on the network
The first part of every IP address contains the network ID, and
the rest of the address contains the host ID. The length of the
network ID depends on the network's class (see following
section). The table below shows the structure of an IP address.
Field1 Field2 Field3 Field4
Class A Network ID Host ID
Class B Network ID Host ID
Class C Network ID Host ID
Here are some examples of valid IP addresses:
Class A: 10.30.6.125 (network = 10, host = 30.6.125)
Class B: 129.88.16.49 (network = 129.88, host = 16.49)
Class C: 192.60.201.11 (network = 192.60.201, host = 11)
Network classes
The three commonly used network classes are A, B, and C.
(There is also a class D but it has a special use beyond the
User’s Guide IP Addresses, Network Masks, and Subnets
216
scope of this discussion.) These classes have different uses
and characteristics.
Class A networks are the Internet's largest networks, each with
room for over 16 million hosts. Up to 126 of these huge
networks can exist, for a total of over 2 billion hosts. Because of
their huge size, these networks are used for WANs and by
organizations at the infrastructure level of the Internet, such as
your ISP.
Class B networks are smaller but still quite large, each able to
hold over 65,000 hosts. There can be up to 16,384 class B
networks in existence. A class B network might be appropriate
for a large organization such as a business or government
agency.
Class C networks are the smallest, only able to hold 254 hosts
at most, but the total possible number of class C networks
exceeds 2 million (2,097,152 to be exact). LANs connected to
the Internet are usually class C networks.
Some important notes regarding IP addresses:
• The class can be determined easily from field1:
field1 = 1-126: Class A
field1 = 128-191: Class B
field1 = 192-223: Class C
(field1 values not shown are reserved for special uses)
• A host ID can have any value except all fields set to 0 or all
fields set to 255, as those values are reserved for special
uses.
Subnet masks
Definition
mask
A mask looks like a regular IP address, but contains a pattern of
bits that tells what parts of an IP address are the network ID and
what parts are the host ID: bits set to 1 mean "this bit is part of the
network ID" and bits set to 0 mean "this bit is part of the host ID."
Subnet masks are used to define subnets (what you get after
dividing a network into smaller pieces). A subnet's network ID is
created by "borrowing" one or more bits from the host ID portion
of the address. The subnet mask identifies these host ID bits.
For example, consider a class C network 192.168.1. To split this
into two subnets, you would use the subnet mask:
255.255.255.128
It's easier to see what's happening if we write this in binary:
11111111. 11111111. 11111111.10000000
As with any class C address, all of the bits in field1 through
field3 are part of the network ID, but note how the mask
specifies that the first bit in field4 is also included. Since this
extra bit has only two values (0 and 1), this means there are two
subnets. Each subnet uses the remaining 7 bits in field4 for its
host IDs, which range from 1 to 126 hosts (instead of the usual
0 to 255 for a class C address).
Similarly, to split a class C network into four subnets, the mask
is:
User’s Guide IP Addresses, Network Masks, and Subnets
217
255.255.255.192 or 11111111. 11111111.
11111111.11000000
The two extra bits in field4 can have four values (00, 01, 10, 11),
so there are four subnets. Each subnet uses the remaining six
bits in field4 for its host IDs, ranging from 1 to 62.
Note
Sometimes a subnet mask does not specify any additional
network ID bits, and thus no subnets. Such a mask is called a
default subnet mask. These masks are:
Class A: 255.0.0.0
Class B: 255.255.0.0
Class C: 255.255.255.0
These are called default because they are used when a network is
initially configured, at which time it has no subnets.

Diagnosing Problem using IP Utilities
ping
Ping is a command you can use to check whether your PC can
recognize other computers on your network and the Internet. A
ping command sends a message to the computer you specify. If
the computer receives the message, it sends messages in reply.
To use it, you must know the IP address of the computer with
which you are trying to communicate.
On Windows-based computers, you can execute a ping
command from the Start menu. Click the Start button, and then
click Run. In the Open text box, type a statement such as the
following:
ping 192.168.1.1
Click OK. You can substitute any private IP address on your
LAN or a public IP address for an Internet site, if known.
If the target computer receives the message, a Command
Prompt window is displayed:
Figure 14: Using the ping Utility
If the target computer cannot be located, you will receive the
message Request timed out.
Using the ping command, you can test whether the path to the
Wireless ADSL2+ Router is working (using the preconfigured
default LAN IP address 192.168.1.1) or another address you
assigned.
You can also test whether access to the Internet is working by
typing an external address, such as that for www.yahoo.com
(216.115.108.243). If you do not know the IP address of a
particular Internet location, you can use the nslookup command,
as explained in the following section.
From most other IP-enabled operating systems, you can
execute the same command at a command prompt or through a
system administration utility.
User’s Guide Troubleshooting
221
nslookup
You can use the nslookup command to determine the IP
address associated with an Internet site name. You specify the
common name, and the nslookup command looks up the name
in on your DNS server (usually located with your ISP). If that
name is not an entry in your ISP’s DNS table, the request is
then referred to another higher-level server, and so on, until the
entry is found. The server then returns the associated IP
address.
On Windows-based computers, you can execute the nslookup
command from the Start menu. Click the Start button, and then
click Run. In the Open text box, type the following:
Nslookup
Click OK. A Command Prompt window displays with a bracket
prompt (>). At the prompt, type the name of the Internet address
that you are interested in, such as www.microsoft.com.
The window will display the associate IP address, if known, as
shown below:
Figure 15: Using the nslookup Utility
There may be several addresses associated with an Internet
name. This is common for web sites that receive heavy traffic;
they use multiple, redundant servers to carry the same
information.
To exit from the nslookup utility, type exit and press [Enter] at
the command prompt.

The DNS maps domain names into IP addresses. DNS
information is distributed hierarchically throughout the
Internet among computers called DNS servers. For example,
www.yahoo.com is the domain name associated with IP
address 216.115.108.243. When you start to access a web
site, a DNS server looks up the requested domain name to
find its corresponding IP address. If the DNS server cannot
find the IP address, it communicates with higher-level DNS
servers to determine the IP address. See domain name.
domain name A domain name is a user-friendly name used in place of its
associated IP address. Domain names must be unique; their
assignment is controlled by the Internet Corporation for

IP address Internet Protocol address
The address of a host (computer) on the Internet, consisting
of four numbers, each from 0 to 255, separated by periods,
e.g., 209.191.4.240. An IP address consists of a network ID
that identifies the particular network the host belongs to, and
a host ID uniquely identifying the host itself on that network.

network A group of computers that are connected together, allowing
them to communicate with each other and share resources,
such as software, files, etc. A network can be small, such as
a LAN, or very large, such as the Internet.
network mask A network mask is a sequence of bits applied to an IP
address to select the network ID while ignoring the host ID.
Bits set to 1 mean "select this bit" while bits set to 0 mean
"ignore this bit." For example, if the network mask
255.255.255.0 is applied to the IP address 100.10.50.1, the
network ID is 100.10.50, and the host ID is 1. See binary, IP
address, subnet.
NIC Network Interface Card
An adapter card that plugs into your computer and provides
the physical interface to your network cabling. For Ethernet
NICs this is typically an RJ-45 connector. See Ethernet, RJ-
45.
packet Data transmitted on a network consists of units called
packets. Each packet contains a payload (the data), plus
overhead information such as where it came from (source
address) and where it should go (destination address).
ping Packet Internet (or Inter-Network) Groper
A program used to verify whether the host associated with an
IP address is online. It can also be used to reveal the IP
address for a given domain name.
port A physical access point to a device such as a computer or
Router, through which data flows into and out of the device.
PPP Point-to-Point Protocol
A protocol for serial data transmission that is used to carry IP
(and other protocol) data between your ISP and your
computer. The WAN interface on the Wireless ADSL2+
Router uses two forms of PPP called PPPoA and PPPoE.
See PPPoA, PPPoE.
PPPoA Point-to-Point Protocol over ATM
One of the two types of PPP interfaces you can define for a
Virtual Circuit (VC), the other type being PPPoE. You can
define only one PPPoA interface per VC.
PPPoE Point-to-Point Protocol over Ethernet
One of the two types of PPP interfaces you can define for a
Virtual Circuit (VC), the other type being PPPoA. You can
define one or more PPPoE interfaces per VC.
protocol A set of rules governing the transmission of data. In order for
a data transmission to work, both ends of the connection
have to follow the rules of the protocol.
remote In a physically separate location. For example, an employee
away on travel who logs in to the company’s intranet is a
remote user.
RIP Routing Information Protocol
The original TCP/IP routing protocol. There are two versions
of RIP: version I and version II.
RJ-11 Registered Jack Standard-11
The standard plug used to connect telephones, fax machines,
modems, etc. to a telephone port. It is a 6-pin connector
usually containing four wires.
User’s Guide Glossary
226
RJ-45 Registered Jack Standard-45
The 8-pin plug used in transmitting data over phone lines.
Ethernet cabling usually uses this type of connector.
routing Forwarding data between your network and the Internet on
the most efficient route, based on the data’s destination IP
address and current network conditions. A device that
performs routing is called a Router.
SDNS Secondary Domain Name System (server)
A DNS server that can be used if the primary DSN server is
not available. See DNS.
subnet A subnet is a portion of a network. The subnet is
distinguished from the larger network by a subnet mask that
selects some of the computers of the network and excludes
all others. The subnet's computers remain physically
connected to the rest of the parent network, but they are
treated as though they were on a separate network. See
network mask.
subnet mask A mask that defines a subnet. See network mask.
TCP See TCP/IP.
TCP/IP Transmission Control Protocol/Internet Protocol
The basic protocols used on the Internet. TCP is responsible
for dividing data up into packets for delivery and
reassembling them at the destination, while IP is responsible
for delivering the packets from source to destination. When
TCP and IP are bundled with higher-level applications such
as HTTP, FTP, Telnet, etc., TCP/IP refers to this whole suite
of protocols.
Telnet An interactive, character-based program used to access a
remote computer. While HTTP (the web protocol) and FTP
only allow you to download files from a remote computer,
Telnet allows you to log into and use a computer from a
remote location.
TFTP Trivial File Transfer Protocol
A protocol for file transfers, TFTP is easier to use than File
Transfer Protocol (FTP) but not as capable or secure.
TKIP Temporal Key Integrity Protocol (TKIP) provides WPA with a
data encryption function. It ensures that a unique master key is
generated for each packet, supports message integrity and
sequencing rules and supports re-keying mechanisms.
triggers Triggers are used to deal with application protocols that create
separate sessions. Some applications, such as NetMeeting,
open secondary connections during normal operations, for
example, a connection to a server is established using one port,
but data transfers are performed on a separate connection. A
trigger tells the device to expect these secondary sessions and
how to handle them.
Once you set a trigger, the embedded IP address of each
incoming packet is replaced by the correct host address so that
NAT can translate packets to the correct destination. You can
specify whether you want to carry out address replacement, and
if so, whether to replace addresses on TCP packets only, UDP
packets only, or both.
twisted pair The ordinary copper telephone wiring used by telephone
companies. It contains one or more wire pairs twisted
User’s Guide Glossary
227
together to reduce inductance and noise. Each telephone
line uses one pair. In homes, it is most often installed with
two pairs. For Ethernet LANs, a higher grade called Category
3 (CAT 3) is used for 10BASE-T networks, and an even
higher grade called Category 5 (CAT 5) is used for
100BASE-T networks. See 10BASE-T, 100BASE-T, Ethernet.
unnumbered interfaces
An unnumbered interface is an IP interface that does not
have a local subnet associated with it. Instead, it uses a
Router-id that serves as the source and destination address
of packets sent to and from the Router. Unlike the IP address
of a normal interface, the Router-id of an unnumbered
interface is allowed to be the same as the IP address of
another interface. For example, the WAN unnumbered
interface of your device uses the same IP address of the
LAN interface (192.168.1.1).
The unnumbered interface is temporary – PPP or DHCP will
assign a ‘real’ IP address automatically.
upstream The direction of data transmission from the user to the
Internet.
VC Virtual Circuit
A connection from your DSL Router to your ISP.
VCI Virtual Circuit Identifier
Together with the Virtual Path Identifier (VPI), the VCI
uniquely identifies a VC. Your ISP will tell you the VCI for
each VC they provide. See VC.
VPI Virtual Path Identifier
Together with the Virtual Circuit Identifier (VCI), the VPI
uniquely identifies a VC. Your ISP will tell you the VPI for
each VC they provide. See VC.
WAN Wide Area Network
Any network spread over a large geographical area, such as
a country or continent. With respect to the Wireless ADSL2+
Router, WAN refers to the Internet.
Web browser A software program that uses Hyper-Text Transfer Protocol
(HTTP) to download information from (and upload to) web
sites, and displays the information, which may consist of text,
graphic images, audio, or video, to the user. Web browsers
use Hyper-Text Transfer Protocol (HTTP). Popular web
browsers include Netscape Navigator and Microsoft Internet
Explorer. See HTTP, web site, WWW.
Web page A web site file typically containing text, graphics and
hyperlinks (cross-references) to the other pages on that web
site, as well as to pages on other web sites. When a user
accesses a web site, the first page that is displayed is called
the home page. See hyperlink, web site.
Web site A computer on the Internet that distributes information to
(and gets information from) remote users through web
browsers. A web site typically consists of web pages that
contain text, graphics, and hyperlinks. See hyperlink, web
page.
WWW World Wide Web
User’s Guide Glossary
228
Also called (the) Web. Collective term for all web sites
anywhere in the world that can be accessed via the Internet.
