Assigning static Internet Information to your PCs
In some cases, you may want to assign Internet information to
some or all of your PCs directly (often called statically), rather
than allowing the ADSL Barricade 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 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

The [NAT Configuration] page allows the user to set the
configuration for the Network Address Translation. The default
setting is [Dynamic NAPT]. It provides dynamic Network Address
Translation capability between LAN and multiple WAN connections,
and the LAN traffic is routed to appropriate WAN connections based
on the destination IP addresses and Route Table. This eliminates
the need for the static NAT session configuration between multiple
LAN clients and multiple WAN connections.
When the [Dynamic NAPT] is chosen, there is no need to configure
the NAT Session and NAT Session Name Configuration.
NAT (Static) and NAPT (Static)
The [NAT] option only maps single WAN IP address to the local
PC IP address. It is peer-to-peer mapping. (1x1) For each WAN
interface, only one local PC IP address can be associated with
each WAN interface. Click the link [Session Name Configuration]
to add the session name for WAN interface.
The [NAPT] option maps the single WAN IP address to many
local PCs IP addresses. (1xN). It is the multiple-mapping
mechanism. For each WAN Interface, more than one local
PCs can be associated with one WAN Interface. Click the link

The [DNS Configuration] page allows the user to set the
configuration of DNS proxy. The firmware supports the DNS
proxy function. For the DHCP requests from local PCs, the
DHCP server will set the LAN port IP as the default DNS server.
Thus, all DNS query messages will come into LAN port first.
The DNS proxy on the ADSL Barricade records the available
DNS servers, and forward DNS query messages to one DNS
server.
[Disable DNS Proxy]
The LAN port does not process the DNS query message. For
the DHCP requests from local PCs, the DHCP server will set the
user-configured preferred DNS server or alternate DNS server
whichever is available as the DNS server. Then all DNS query
messages will be directly sent to the DNS servers.

Some ISPs terminate the PPP session for inactivity reasons.
If [PPP connect on WAN access] is selected, the PPP will be
automatically reconnected when an URL is entered in
the browser (packet interested in going out the WAN).

interfaces
DNS (Domain Name System)
The DNS maps domain names into IP addresses. DNS
information is distributed hierarchically throughout the Internet
among computers called DNS servers. 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 also domain name.
67
Terminology
domain name
A domain name is a user-friendly name used in place of its
associated IP address.
For example, www.globespan.net is the domain name associated
with the IP address 209.191.4.240. Domain names must be
unique. Their assignment is controlled by the Internet
Corporation for Assigned Names and Numbers (ICANN). Domain
names are a key element of URLs, which identify a specific file at
a web site, e.g., http://www.globespan.net/index.html.

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. A network
mask is used to define the network ID and the host ID. Because
IP addresses are difficult to remember, they usually have an
associated domain name that can be specified instead. See

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 also 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, which for Ethernet
NICs 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 assoc i ated 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.
POTS (Plain Old Telephone Service)
Traditional analog telephone service using copper telephone
lines. Pronounced pots. See also PSTN.
73
Terminology
POTS splitter
See splitter.
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 ADSL Barricade uses two forms of P PP
called PPPoA and PPPoE. See also 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 in tranet 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.
74
Terminology
RJ-11 (Registered Jack Standard-11)
The standard plug used to connect telephones, fax machines,
modems, etc. to a telephone jack. It is a 6-pin connector usually
containing four wires.
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.
rule
See filtering rule, NAT rule.
SDNS (Secondary Domain Name System (server))
A DNS server that can be used if the primary DSN server is not
available. See DNS.
SNMP (Simple Network Management Protocol)
The TCP/IP protocol used for network management.
splitter
A device that splits off the voice component of the DSL signal
to a separate line, so that data and telephone service each
have their own wiring and jacks. The splitter is installed by your
telephone company where the DSL line enters your home.
The CO also contains splitters that separate the voice and data
signals, sending voice to the PSTN and data on high-speed lines
to the Internet. See also CO, PSTN, splitterless, microfilter.
75
Terminology
splitterless
A type of DSL installation where no splitter is installed, saving
the cost of a service call by the telephone company. Instead,
each jack in the home carries both voice and data, requiring
a microfilter for each telephone to prevent interference from
the data signal. ADSL is usually splitterless; if you are unsure
if your installation has a splitter, ask your DSL provider.
See also splitter, microfilter.
subnet
A subnet is a portion of a network. The subnet is distinguished
from the larger network by a subnet mask which 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 also network mask.
subnet mask
A mask that defines a subnet. See also 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.
76
Terminology
Telnet
An interactive, character-based program use d 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.
TTL (Time To Live)
A field in an IP packet that limits the life span of that packet.
Originally meant as a time duration, the TTL is usually
represented instead as a maximum hop count; each router
that receives a packet decrements this field by one. When
the TTL reaches zero, the packet is discarded.
twisted pair
The ordinary copper telephone wiring long used by telephone
companies. It contains one or more wire pairs twisted together to
reduce inductance and noise. Each telephone line u ses 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 also 10BASE-T, 100BASE-T, Ethernet.
upstream
The direction of data transmission from the user to the Internet.
VC (Virtual Circuit)
A connection from your ADSL routers to your ISP.
77
Terminology
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 also 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 also VC.
WAN (Wide Area Network)
Any network spread over a large geographical area, such as
a country or continent. With respect to the ADSL Barricade,
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
also 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 also
hyperlink, web site.
78
Terminology
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 also hyperlink, web page.
