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

NAT Configuration

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.

DNS Configuration

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.

Configuration

[Use Auto Discovered DNS Servers Only] The DNS proxy will store the DNS server IP addresses

obtained from DHCP client or PPP into the table. And all DNS query messages will be sent to one of the dynamically obtained DNS servers.

100BASE-T

A designation for the type of wiring used by Ethernet networks with a data rate of 100 Mbps. Also known as Category 5 (CAT 5) wiring. See also data rate, Ethernet.

ADSL (Asymmetric Digital Subscriber Line) The most commonly deployed flavor of DSL for home users. The term asymmetrical refers to its unequal data rates for downloading and uploading (the download rate is higher than the up load ra te). The asymmetrical rates benefit home users because they typically download much more data from the Internet than they upload.

analog

Of data, having a form is analogous to the data's original waveform. The voice component in DSL is an analog signal. See also digital.

ATM (Asynchronous Transfer Mode) A standard for high-speed transmission of data, text, voice, and video, widely used within the Internet. ATM data rates range from 45 Mbps to 2.5 Gbps. See also data rate.

authenticate

To verify a user's identity, such as by prompting for a pa ssword.

Terminology

binary

The base two system of numbers, that uses only two digits, 0 and 1, to represent all numbers. In binary, the number 1 is written as 1, 2 as 10, 3 as 11, 4 as 100, etc. Although expressed as decimal numbers for convenience, IP addresses in actual use are binary numbers; e.g., the IP address 209.191.4.240 is 11010001.10111111.00000100.11110000 in bina ry. See also bit, IP address, network mask.

broadband

A telecommunications technology that can send different types of data over the same medium. DSL is a broadband technology.

broadcast

To send data to all computers on a network. CO (Central Office)

A circuit switch that terminates all the local access lines in a particular geographic serving area. It is a physical building where the local switching equipment is found. xDSL lines running from a subscriber's home connect at their serving central office.

Terminology

DHCP (Dynamic Host Configuration Protocol) DHCP automates address assignment and management. When a computer connects to the LAN, DHCP assigns it an IP address from a shared pool of IP addresses; after a specified time limit, DHCP returns the address to the pool.

DHCP relay (Dynamic Host Configuration Protocol relay) A DHCP relay is a computer that forwards DHCP data between computers that request IP addresses and the DHCP server that assigns the addresses. Each of the ADSL Barricade's can be configured as a DHCP relay. See DHCP.

DHCP server (Dynamic Host Configuration Protocol server) A DHCP server is a computer that is responsible for assigning IP addresses to the computers on a LAN. See DHCP.

digital

Of data, having a form based on discrete values expressed as binary numbers (0's and 1's). The data componen t in DSL is a digital signal. See also analog.

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.

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. See also DNS.

download

To transfer data in the downstream direction, i.e., from the Internet to the user.

DSL (Digital Subscriber Line) A technology that allows both digital data and analog voice signals to travel over existing copper telephone lines.

Ethernet

The most commonly installed computer network technology, usually using twisted pair wiring. Ethernet data rates are 10 Mbps and 100 Mbps. See also BASE-T,100BASE-T, twisted pair.

filtering

To screen out selected types of data, based on filterin g ru les. Filtering can be applied in one direction (upstream or downstream), or in both directions.

filtering rule

A rule that specifies what kinds of data a routing device will accept and/or reject. Filtering rules are defined to operate on an interface (or multiple interfaces) and in a particular direction (upstream, downstream, or both).

Terminology

firewall

Any method of protecting a computer or LAN connected to the Internet from intrusion or attack from the outside. Some firewall protection can be provided by packet filtering and Network Address Translation services.

FTP (File Transfer Protocol) A program used to transfer files between computers connected to the Internet. Common uses include uploading new or updated files to a web server, and downloading files from a web server.

GGP (Gateway to Gateway Protocol) An Internet protocol that specifies how gateway routers communicate with each other.

Gbps

Abbreviation for Gigabits (GIG-uh-bits) per second, or one billion bits per second. Internet data rates are often expressed in Gbps.

GRE (Generic Routing Encapsulation) TCP/IP protocol suite, transport layer encapsulation protocol.

hop

When you send data through the Internet, it is sent first fr om your computer to a router, and then from one router to another until it finally reaches a router that is directly connected to the recipient. Each individual "leg" of the data's journey is called a hop.

hop count

The number of hops that data has taken on its route to its destination. Alternatively, the maximum number of hops that a packet is allowed to take before being discarded. See also TTL.

Terminology

host

A device (usually a computer) connected to a network. HTTP (Hyper-Text Transfer Protocol)

HTTP is the main protocol used to transfer data from web sites so that it can be displayed by web browsers. See also web browser.

ICMP (Internet Control Message Protocol) An Internet protocol used to report errors and other network-rela ted information. The ping command makes use of ICMP.

IGMP (Internet Group Manageme n t Protocol) An Internet protocol that enables a computer to share information about its membership in multicast groups with adjacent routers. A multicast group of computers is one whose members have designated as interested in receiving specific content from the others. Multicasting to an IGMP group can be used to simultaneously update the address books of a group of mobile computer users or to send company newsletters to a distribution list.

IP See TCP/IP.

Terminology

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.

NAT (Network Address Translation) A service performed by many routers that translates your network's publicly known IP address into a Private IP address for each computer on your LAN. Only your router and your LAN know these addresses; the outside world sees only the public IP address when talking to a computer on your LAN.

NAT rule

A defined method for translating between public and private IP addresses on your LAN.

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.

Terminology

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 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.

Terminology

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.

Terminology

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.

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.

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.

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.
