NAT (Network Address Translation)
NAT is a function allows several networked PCs to share an Internet account using only a single IP address, which may be statically or dynamically assigned by your Service Provider. Click “Add” to add more rule to NAT Configuration.
The WMG accomplishes this address sharing by translating the internal LAN IP addresses to public unique address/addresses on the Internet. The internal LAN IP addresses can be either private addresses or registered addresses. In NAT type, you can choose Many-to-one or Many-to-many. In Many-to-one configuration, it translates multiple LAN IP addresses to one single public address on Internet. In Many-to-many configuration, it translates multiple LAN IP addresses to a range of public addresses. This will be used when your service provider provide you a range of IP addresses.
DMZ
A DMZ (Demilitarized Zone) is a buffer zone between the Internet, and your private networks. It can be a public network typically used for Web, FTP and E-Mail servers that are accessed by external clients on the Internet. Separating these public access server with your private network provide higher security for your network.
A DMZ Host is a computer that has all external Internet traffic forwarded to it. This allows a computer to be exposed to unrestricted two-way communication. This feature should be used only when necessary, since it is not protected by any security rules of the firewall.

ViewSonic Wireless Media Gateway 78
Glossary
10BaseT. An IEEE standard (802.3) for operating 10 Mbps
Ethernet networks (LANs) with twisted pair cabling and a wiring hub.
802.11 standard. 802.11 or IEEE 802.11 is a type of radio
technology used for wireless local area networks (WLANs). It is a standard that has been developed by the IEEE (Institute of Electrical and Electronic Engineers), http://standards.ieee.org. The IEEE is an international organization that develops standards for hundreds of electronic and electrical technologies. The organization uses a series of numbers, like the Dewey Decimal system in libraries, to differentiate between the various technology families.
The 802 subgroup (of the IEEE) develops standards for local and wide area networks with the 802.11 section reviewing and creating standards for wireless local area networks.
802.11 is composed of several standards operating in different
radio frequencies: 802.11b is a standard for wireless LANs operating in the 2.4 GHz spectrum with a bandwidth of 11 Mbps;
802.11a is a different standard for wireless LANs, and pertains to
systems operating in the 5 GHz frequency range with a bandwidth of 54 Mbps. Another standard, 802.11g, is for WLANS operating in the 2.4 GHz frequency but with a bandwidth of 54 Mbps.
ViewSonic Wireless Media Gateway 79
802.11a. An IEEE specification for wireless networking that
operates in the 5 GHz frequency range (5.725 GHz to 5.850 GHz) with a maximum 54 Mbps data transfer rate. The 5 GHz frequency band is not as crowded as the 2.4 GHz frequency, because the
802.11a specification offers more radio channels than the 802.11b.
These additional channels can help avoid radio and microwave interference.
802.11b. International standard for wireless networking that
operates in the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and provides a throughput of up to 11 Mbps. This is a very commonly used frequency. Microwave ovens, cordless phones, medical and scientific equipment, as well as Bluetooth devices, all work within the 2.4 GHz frequency band.
802.11g. Similar to 802.11b, but this standard provides a
throughput of up to 54 Mbps. It also operates in the 2.4 GHz frequency band but uses a different radio technology in order to boost overall bandwidth.
Access point. A wireless LAN transceiver or “gateway” that can connect a wired LAN to one or many wireless devices. Access points can also bridge to each other. There are various types of access points and base stations used in both wireless and wired networks. These include bridges, hubs, switches, and Gateways. The differences between them are not always precise, because certain capabilities associated with one can also be added to another. For example, a Gateway can do bridging, and a hub may
ViewSonic Wireless Media Gateway 80
also be a switch. But they are all involved in making sure data is transferred from one location to another.
A bridge connects devices that all use the same kind of protocol. A Gateway can connect networks that use differing protocols. It also reads the addresses included in the packets and routes them to the appropriate computer station, working with any other Gateway in the network to choose the best path to send the packets on. A wireless hub or access point adds a few capabilities such as roaming and provides a network connection to a variety of clients, but it does not allocate bandwidth. A switch is a hub that has extra intelligence: It can read the address of a packet and send it to the appropriate computer station. A wireless gateway is an access point that provides additional capabilities such as NAT routing, DHCP, firewalls, security, etc.
Ad-Hoc mode. A client setting that provides independent peer-to­peer connectivity in a wireless LAN. An alternative set-up is one where PCs communicate with each other through an AP.
Applet. An application or utility program that is designed to do a very specific and limited task.
Backbone. The central part of a large network that links two or more subnetworks and is the primary path for data transmission for a large business or corporation. A network can have a wired backbone or a wireless backbone.
ViewSonic Wireless Media Gateway 81
Bandwidth. The amount of transmission capacity that is available
on a network at any point in time. Available bandwidth depends on several variables such as the rate of data transmission speed between networked devices, network overhead, number of users, and the type of device used to connect PCs to a network. It is similar to a pipeline in that capacity is determined by size: the wider the pipe, the more water can flow through it; the more bandwidth a network provides, the more data can flow through it. Standard
802.11b provides a bandwidth of 11 Mbps; 802.11a and 802.11g
provide a bandwidth of 54 Mbps.
Bits per second (bps). A measure of data transmission speed over communication lines based on the number of bits that can be sent or received per second. Bits per second—bps—is often confused with bytes per second—Bps. While "bits" is a measure of transmission speed, "bytes" is a measure of storage capability. 8 bits make a byte, so if a wireless network is operating at a bandwidth of 11 megabits per second (11 Mbps or 11 Mbits/sec), it is sending data at 1.375 megabytes per second (1.375 MBps).
Bluetooth wireless technology. A technology specification for linking portable computers, personal digital assistants (PDAs) and mobile phones for short-range transmission of voice and data across a global radio frequency band without the need for cables or wires. Bluetooth is a frequency-hopping technology in the 2.4 GHz frequency spectrum, with a range of 30 feet.
Bridge. A product that connects a local area network (LAN) to another local area network that uses the same protocol (for
ViewSonic Wireless Media Gateway 82
example, wireless, Ethernet or token ring). Wireless bridges are commonly used to link buildings in campuses.
Broadband. A comparatively fast Internet connection. Services such as ISDN, cable modem, DSL and satellite are all considered broadband as compared to dial-up Internet access. There is no official speed definition of broadband but services of 100Kbps and above are commonly thought of as broadband.
Bus adapter. A special adapter card that installs in a PC’s PCI or ISA slot and enables the use of PC Card radios in desktop computers. Some companies offer one-piece PCI or ISA Card radios that install directly into an open PC or ISA slot.
Cable modem. A kind of converter used to connect a computer to a cable TV service that provides Internet access. Most cable modems have an Ethernet out-cable that then attaches to the user's ‘ gateway.
Client. Any computer connected to a network that requests services (files, print capability) from another member of the network.
Client devices. Clients are end users. Wi-Fi client devices include PC Cards that slide into laptop computers, mini-PCI modules embedded in laptop computers and mobile computing devices, as well as USB radios and PCI/ISA bus Wi-Fi radios. Client devices usually communicate with hub devices like access points and gateways.

Collision avoidance. A network node characteristic for proactively
detecting that it can transmit a signal without risking a collision.
Crossover cable. A special cable used for networking two computers without the use of a hub. Crossover cables may also be required for connecting a cable or DSL modem to a wireless gateway or access point. Instead of the signals transferring in parallel paths from one set of plugs to another, the signals "crossover." If an eight-wire cable was being used, for instance, the signal would start on pin one at one end of the cable and end up on pin eight at the other end. They "cross-over" from one side to the other.
ViewSonic Wireless Media Gateway 84
CSMA/CA (Carrier Sense Multiple Access with Collision
Avoidance). The principle medium access method employed by IEEE 802.11 WLANs. It is a "listen before talk": method of minimizing (but not eliminating) collisions caused by simultaneous transmission by multiple radios. IEEE 802.11 states collision avoidance method rather than collision detection must be used, because the standard employs half duplex radios—radios capable of transmission or reception—but not both simultaneously. Unlike conventional wired Ethernet nodes, a WLAN station cannot detect a collision while transmitting. If a collision occurs, the transmitting station will not receive an ACKnowledge packet from the intended receive station. For this reason, ACK packets have a higher priority than all other network traffic. After completion of a data transmission, the receive station will begin transmission of the ACK packet before any other node can begin transmitting a new data packet. All other stations must wait a longer pseudo randomized period of time before transmitting. If an ACK packet is not received, the transmitting station will wait for a subsequent opportunity to retry transmission.
CSMA/CD (Carrier Sense Multiple Access/Collision Detection). A method of managing traffic and reducing noise on an Ethernet network. A network device transmits data after detecting that a channel is available. However, if two devices transmit data simultaneously, the sending devices detect a collision and retransmit after a random time delay.
DC power module. Modules that convert AC power to DC. Depending on manufacturer and product, these modules can range
ViewSonic Wireless Media Gateway 85
from typical "wall wart" transformers that plug into a wall socket and provide DC power via a tiny plug to larger, enterprise-level Power Over Ethernet systems that inject DC power into the Ethernet cables connecting access points.
DHCP (Dynamic Host Configuration Protocol). A utility that enables a server to dynamically assign IP addresses from a predefined list and limit their time of use so that they can be reassigned. Without DHCP, an IT Manager would have to manually enter in all the IP addresses of all the computers on the network. When DHCP is used, whenever a computer logs onto the network, it automatically gets an IP address assigned to it.
Dial-up. A communication connection via the standard telephone network, or Plain Old Telephone Service (POTS).
Diversity antenna - A type of antenna system that uses two antennas to maximize reception and transmission quality and reduce interference.
DNS (Domain Name System, or Service, or Server). A program that translates URLs to IP addresses by accessing a database maintained on a collection of Internet servers. The program works behind the scenes to facilitate surfing the Web with alpha versus numeric addresses. A DNS server converts a name like mywebsite.com to a series of numbers like 107.22.55.26. Every website has its own specific IP address on the Internet.
ViewSonic Wireless Media Gateway 86
DSL (Digital Subscriber Lines). Various technology protocols for
high-speed data, voice and video transmission over ordinary twisted-pair copper POTS (Plain Old Telephone Service) telephone wires.
Encryption key. An alphanumeric (letters and/or numbers) series that enables data to be encrypted and then decrypted so it can be safely shared among members of a network. WEP uses an encryption key that automatically encrypts outgoing wireless data. On the receiving side, the same encryption key enables the computer to automatically decrypt the information so it can be read.
ESSID (Extended Service Set ID). The identifying name of an
802.11 wireless network. When you specify your correct ESSID in
your client setup you ensure that you connect to your wireless network rather than another network in range. (See SSID.) The ESSID can be called by different terms, such as Network Name, Preferred Network, SSID or Wireless LAN Service Area.
Ethernet. International standard networking technology for wired implementations. Basic 10BaseT networks offer a bandwidth of about 10 Mbps. Fast Ethernet (100 Mbps) and Gigabit Ethernet (1000 Mbps) are becoming popular.
Firewall. A system that secures a network and prevents access by unauthorized users. Firewalls can be software, hardware or a combination of both. Firewalls can prevent unrestricted access into a network, as well as restrict data from flowing out of a network.
ViewSonic Wireless Media Gateway 87
Gateway. In the wireless world, a gateway is an access point with
additional software capabilities such as providing NAT and DHCP. Gateways may also provide VPN support, roaming, firewalls, various levels of security, etc.
HotSpot. A place where you can access Wi-Fi service. This can be for free or for a fee. HotSpots can be inside a coffeeshop, airport lounge, train station, convention center, hotel or any other public meeting area. Corporations and campuses are also implementing HotSpots to provide wireless Internet access to their visitors and guests. In some parts of the world, HotSpots are known as CoolSpots.
Hub. A multiport device used to connect PCs to a network via Ethernet cabling or via WiFi. Wired hubs can have numerous ports and can transmit data at speeds ranging from 10 Mbps to multigigabyte speeds per second. A hub transmits packets it receives to all the connected ports. A small wired hub may only connect four computers; a large hub can connect 48 or more. Wireless hubs can connect hundreds.
HZ (Hertz). The international unit for measuring frequency, equivalent to the older unit of cycles per second. One megahertz (MHz) is one million hertz. One gigahertz (GHz) is one billion hertz. The standard US electrical power frequency is 60 Hz, the AM broadcast radio frequency band is 535—1605 kHz, the FM broadcast radio frequency band is 88—108 MHz, and wireless
802.11b LANs operate at 2.4 GHz.

IEEE (Institute of Electrical and Electronics Engineers), New York,
www.ieee.org. A membership organization that includes engineers, scientists and students in electronics and allied fields. It has more than 300,000 members and is involved with setting standards for computers and communications.
IEEE802.11. A set of specifications for LANs from The Institute of Electrical and Electronics Engineers (IEEE). Most wired networks conform to 802.3, the specification for CSMA/CD based Ethernet networks or 802.5, the specification for token ring networks. 802.11 defines the standard for wireless LANs encompassing three incompatible (non-interoperable) technologies: Frequency Hopping Spread Spectrum (FHSS), Direct Sequence Spread Spectrum (DSSS) and Infrared. WECA’s focus is on 802.11b, an 11 Mbps high-rate DSSS standard for wireless networks.
Infrastructure mode. A client setting providing connectivity to an AP. As compared to Ad-Hoc mode, whereby PCs communicate directly with each other, clients set in Infrastructure Mode all pass data through a central AP. The AP not only mediates wireless network traffic in the immediate neighborhood, but also provides communication with the wired network. See Ad-Hoc and AP.
Internet appliance. A computer that is intended primarily for Internet access, is simple to set up and usually does not support installation of third-party software. These computers generally offer customized web browsing, touch-screen navigation, e-mail services, entertainment and personal information management
ViewSonic Wireless Media Gateway 89
applications. An Internet appliance can be Wi-Fi enabled or it can be connected via a cable to the local network.
IP (telephony). Technology that supports voice, data and video transmission via IP-based LANs, WANs, and the Internet. This includes VoIP (Voice over IP).
IP address. A 32-bit number that identifies each sender or receiver of information that is sent across the Internet. An IP address has two parts: an identifier of a particular network on the Internet and an identifier of the particular device (which can be a server or a workstation) within that network.
IPX-SPX (Internetwork Packet Exchange-Sequenced Packet Exchange). IPX is a networking protocol used by the Novell NetWare operating systems. Like UDP/IP, IPX is a datagram protocol used for connectionless communications. Higher-level protocols, such as SPX and NCP, are used for additional error recovery services. SPX is a transport layer protocol (layer 4 of the OSI Model) used in Novell Netware networks. The SPX layer sits on top of the IPX layer (layer 3) and provides connection-oriented services between two nodes on the network. SPX is used primarily by client/server applications. Whereas the IPX protocol is similar to IP, SPX is similar to TCP. Together, therefore, IPX-SPX provides connection services similar to TCP/IP.
ISA (Industry Standard Architecture). A type of internal computer bus that allows the addition of card-based components like
ViewSonic Wireless Media Gateway 90
modems and network adapters. ISA has been replaced by PCI and is not very common anymore.
ISO Network Model (International Standards Organization). A network model developed by the ISO that consists of seven different levels, or layers. By standardizing these layers, and the interfaces in between, different portions of a given protocol can be modified or changed as technologies advance or systems requirements are altered. The seven layers are:
Physical
Data Link
Network
Transport
Session
Presentation
Application
The IEEE 802.11 Standard encompasses the physical layer (PHY) and the lower portion of the data link layer. The lower portion of the data link layer is often referred to as the Medium Access Controller (MAC) sublayer.
ISS (Internet Security Services). A special software application that allows all PCs on a network access to the Internet simultaneously through a single connection and Internet Service Provider (ISP) account.
LAN (Local Area Network). A system of connecting PCs and other devices within the same physical proximity for sharing resources
ViewSonic Wireless Media Gateway 91
such as an Internet connections, printers, files and drives. When Wi-Fi is used to connect the devices, the system is known as a wireless LAN or WLAN.
MAC (Medium Access Controller). Every wireless 802.11 device has its own specific MAC address hard-coded into it. This unique identifier can be used to provide security for wireless networks. When a network uses a MAC table, only the 802.11 radios that have had their MAC addresses added to that network’s MAC table will be able to get onto the network.
Mapping. Assigning a PC to a shared drive or printer port on a network.
NAT (Network Address Translation). A network capability that enables a houseful of computers to dynamically share a single incoming IP address from a dial-up, cable or xDSL connection. NAT takes the single incoming IP address and creates new IP address for each client computer on the network. NAT provides a type of firewall by hiding internal IP addresses.
Network name. Identifies the wireless network for all the shared components. During the installation process for most wireless networks, enter the network name or SSID. Different network names are used when setting up your individual computer, wired network or workgroup.
NIC (Network Interface Card). An expansion board you insert into a computer so the computer can be connected to a network. A NIC is
ViewSonic Wireless Media Gateway 92
a type of PC adapter card that either works without wires (Wi-Fi) or attaches to a network cable to provide two-way communication between the computer and network devices such as a hub or switch. Most office wired NICs operate at 10 Mbps (Ethernet), 100 Mbps (Fast Ethernet) or 10/100 Mbps dual speed. High-speed Gigabit and 10 Gigabit NIC cards are also available. See PC Card.
PC Card. A removable, credit-card-sized memory or I/O device that fits into a Type 2 PCMCIA standard slot, PC Cards are used primarily in PCs, portable computers, PDAs and laptops. PC Card peripherals include Wi-Fi cards, memory cards, modems, NICs, hard drives, etc.
PCI (Peripheral Component Interconnect). A high-performance I/O computer bus used internally on most computers. Other bus types include ISA and AGP. PCIs and other computer buses enable the addition of internal cards that provide services and features not supported by the motherboard or other connectors.
PCMCIA (Personal Computer Memory Card International Association). Expansion cards now referred to as “PC Cards” were originally called “PCMCIA Cards” because they met the standards created by the PCMCIA.
ViewSonic Wireless Media Gateway 93
Peer-to-peer network. A wireless or wired computer network that
has no server or central hub or Gateway. All the networked PCs are equally able to act as a network server or client, and each client computer can talk to all the other wireless computers without having to go through an access point or hub. However, since there is no central base station to monitor traffic or provide Internet access, the various signals can collide with each other, reducing overall performance.
PHY (Physical Layer). The lowest layer within the OSI Network Model. It deals primarily with transmission of the raw bit stream over the PHYsical transport medium. In the case of wireless LANs, the transport medium is free space. The PHY defines parameters such as data rates, modulation method, signaling parameters, transmitter/receiver synchronization, etc. Within an actual radio implementation, the PHY corresponds to the radio front end and baseband signal processing sections.
Proxy server. Used in larger companies and organizations to improve network operations and security, a proxy server is able to prevent direct communication between two or more networks. The proxy server forwards allowable data requests to remote servers and/or responds to data requests directly from stored remote server data.
Range. How far will your wireless network stretch? Most Wi-Fi systems will provide a range of a hundred feet or more. Depending on the environment and the type of antenna used, Wi-Fi signals can have a range of up to mile.
ViewSonic Wireless Media Gateway 94
Residential gateway. A wireless device that connects multiple
PCs, peripherals and the Internet on a home network. Most Wi-Fi residential gateways provide DHCP and NAT as well.
RJ-45. Standard connectors used in Ethernet networks. Even though they look very similar to standard RJ-11 telephone connectors, RJ-45 connectors can have up to eight wires, whereas telephone connectors have only four.
Roaming. Moving seamlessly from one AP coverage area to another with no loss in connectivity.
Router. A device that forwards data packets from one local area network (LAN) or wide area network (WAN) to another. Based on routing tables and routing protocols, routers can read the network address in each transmitted frame and make a decision on how to send it via the most efficient route based on traffic load, line costs, speed, bad connections, etc.
Server. A computer that provides its resources to other computers and devices on a network. These include print servers, Internet servers and data servers. A server can also be combined with a hub or router.
SSID (Service Set Identifier). A 32-character unique identifier attached to the header of packets sent over a WLAN that acts as a password when a mobile device tries to connect to the BSS. (Also called ESSID.) The SSID differentiates one WLAN from another, so all access points and all devices attempting to connect to a specific
