Wireless Cable/DSL RouterChapter 1: IntroductionThink of the Network Everywhere Wireless Cable/DSL Router as a kind of"splitter" for your Internet connection. Just connect your DSL or CableModem to the Router, and all the computers in your household can share theInternet -- all at the same time. You can connect your home computers to theRouter with Ethernet cables, or put wireless network adapters in them and com-municate over radio waves, saving the trouble and expense of running cablesthrough your house.Once your computers are connected to the Router, they can communicate witheach other too, sharing resources and files. All your computers can print on ashared printer connected anywhere in the house. And your computers can shareall kinds of files -- music, digital pictures, and documents. Keep all your dig-ital music on one computer, and listen to it anywhere in the house. Organizeall of your family's digital pictures in one place, to simplify finding the onesyou want, and easing backup to CD-R. Utilize extra free space on one com-puter when another's hard drive starts to fill up.Your home network is secure, too. All wireless communications are protectedby 128-bit encryption. Internet Firewall packet filters keep intruders out, andblock attacks. Parental Controls help you protect your family.It's all easier thanyou think -- the included Setup Wizard takes you through configuring your net-work, step by step.

In this instance, the Router connects your Local Area Network (LAN), or thegroup of PCs in your home or office, to the Wide Area Network (WAN) that isthe Internet. The Router processes and regulates the data that travels betweenthese two networks. Think of the Router as a network device with two sides. The first side is madeup of your private Local Area Network (LAN) of PCs. The other, public sideis the Internet, or the Wide Area Network (WAN), outside of your home oroffice. The Router’s firewall (NAT) protects your network of PCs so users on the pub-lic, Internet side cannot “see” your PCs. This is how your LAN, or network,remains private. The Router protects your network by inspecting the first pack-et coming in from the Internet port before delivery to the final destination onthe LAN port. The Router inspects Internet port services like the web server,ftp server, or other Internet applications, and, if allowed, it will forward thepacket to the appropriate PC on the LAN side.What’s an IP Address?IP stands for Internet Protocol. Every device on an IP-based network, includ-ing PCs, print servers, and routers, requires an IP address to identify its “loca-tion,” or address, on the network. This applies to both the Internet and LANconnections.There are two ways of assigning an IP address to your network devices. Static IP AddressesA static IP address is a fixed IP address that you assign manually to a PC orother device on the network. Since a static IP address remains valid until youdisable it, static IP addressing insures that the device assigned it will have thatsame IP address until you change it. Static IP addresses are commonly usedwith network devices such as server PCs or print servers.If you use the Router to share your cable or DSL Internet connection, contactyour ISP to find out if they have assigned a static IP address to your account.If so, you will need that static IP address when configuring the Router. You canget the information from your ISP.IP AddressesAn Introduction to LANs and WANs1
Dynamic IP AddressesA dynamic IP address is automatically assigned to a device on the network,such as PCs and print servers. These IP addresses are called “dynamic”because they are only temporarily assigned to the PC or device. After a certaintime period, they expire and may change. If a PC logs on to the network (or theInternet) and its dynamic IP address has expired, the DHCP server will assignit a new dynamic IP address.For DSL users, many ISPs may require you to log on with a user name andpassword to gain access to the Internet. This is called “Point to Point Protocolover Ethernet” or PPPoE. PPPoE is similar to a dial-up connection but does nothave a phone number to dial into, and PPPoE is a dedicated high-speed con-nection. PPPoE also will provide the Router with a dynamic IP address toestablish a connection to the Internet.DHCP (Dynamic Host Configuration Protocol) ServersDHCP frees you from having to assign IP addresses manually every time a newuser is added to your network. PCs and other network devices using dynamicIP addressing are assigned a new IP address by a DHCP server. The PC or net-work device obtaining an IP address is called the DHCP client. The Router’sInternet port is, by default, set as a DHCP client.DHCP servers can either be a designated PC on the network or another networkdevice, such as the Router. By default, a DHCP server is enabled on yourRouter’s LAN ports. If you already have a DHCP server running on your net-work, you must disable one of the two DHCP servers. If you run more than oneDHCP server on your network, you will experience network errors, such asconflicting IP addresses. To disable the Router’s DHCP function, see theDHCP section in Chapter 6: The Router’s Web-Based Utility.Note: Even if you assign a static IP address to a PC, other PCs can still useDHCP’s dynamic IP addressing, as long as the static IP is not within theDHCP range of the LAN IP Address.If the Router’s DHCP function fails to provide a dynamic IP address for anyreason, please refer to Appendix A: Troubleshooting.TheRouter’s rear panel (as shown in Figure 1-1) is where all of its connections aremade.Internet The Internet Port is where you will connect your cable orDSL modem with an Ethernet cable. Your modem con-nection will not work from any other port. Ports 4, 3, 2 These four LAN (Local Area Network) ports are whereyou will connect networked devices, such as PCs, printservers, and any other Ethernet devices you want to puton your network. If Port 1 is being used, the Uplink Portwill not work.Port 1/Uplink Port The Uplink Port is where you can expand your networkby connecting to a switch. Uplinking to a switch is doneby simply running a cable from the Uplink Port to theother device. The Uplink Port is shared with Port 1.Pushing in the Uplink button allows this port to be usedas the Uplink port. If the Uplink button is not pushed in,this port functions the same as Ports 4, 3, and 2.Power The Power Port is where you will connect the includedAC Power adapter.Figure 1-1The Router’s PortsNote: Since the Router is a device that connects two networks, it needs twoIP addresses—one for the LAN side, and one for the Internet side. In thisUser Guide, you’ll see references to the “Internet IP address” and the “LANIP address.”Since the Router has firewall security (NAT), only the Router’s Internet IPaddress can be seen from the Internet.However, even the Internet IP address can be blocked, so that the Router andnetwork seem invisible to the Internet—This is shown in the Filters section in“Chapter 6: The Routers Web-Based Utility”.

This LED indicates that the Router’s wireless func-tions have been enabled through the Web-based utility.Power Green. This LED indicates that the Router’s power is on.Link/Act Green. This LED serves two purposes. When this LED is litcontinuously, this indicates that the Router is connected to adevice through the corresponding port (1, 2, 3, or 4). A blink-ing LED indicates that the Router is actively sending orreceiving data over that port. When the Uplink Port is in use,the LED for Port 1 will be lit continuously.The Router’s LEDsThe RReset BButtonPressing the Reset Button and holding it in for a few seconds will clear allof the Router’s data and restore the factory defaults. This should be doneonly if you are experiencing heavy routing problems, and only after youhave exhausted all of the other troubleshooting options. By resetting theRouter, you run the risk of creating conflicts between your PCs’ actual IPAddresses and what the Router thinks their IP Addresses should be. Youmay be forced to reboot each network PC.If the Router locks up, simply press the reset button or power it down forthree to five seconds by removing the power cable from the Router’sPower Port. Leaving the power off for too long could result in the loss ofnetwork connections.Figure 1-2Full/Col Green. This LED also serves two purposes. When this LEDis lit continuously, the connection made through the corre-sponding port is running in Full Duplex mode.

Chapter 2: Planning Your WirelessNetworkA wireless LAN is exactly like a regular LAN, except that each computer in theLAN uses a wireless adapter to connect to the network through a wireless con-nection. Computers in a wireless LAN must be configured to share the sameradio channel.The wireless adapter provides LAN access for wireless workstations. An inte-grated wireless and wired LAN is called an Infrastructure configuration. Agroup of wireless adapter users and this Router compose a Basic Service Set(BSS). Each PC equipped with a wireless adapter in a BSS can talk to anycomputer in a wired LAN infrastructure via this Router.An infrastructure configuration extends the accessibility of a PC with a wire-less adapter to a wired LAN, and doubles the effective wireless transmissionrange for two PCs equipped with a wireless adapter Since this Router is ableto forward data within its BSS, the effective transmission range in an infra-structure LAN is doubled.Infrastructure mode also supports roaming capabilities for mobile users. Morethan one BSS can be configured as an Extended Service Set (ESS). This con-tinuous network allows users to roam freely within an ESS. All PCs that areequipped with a wireless adapter, and are within one ESS, must be configuredwith the same ESS ID.Before enabling an ESS with roaming capability, it is recommended to select afeasible radio channel and optimum Router position. Proper positioning com-bined with a clear radio signal will greatly enhance performance.RoamingNetwork TopologyChapter 3: Connecting the RouterBefore plugging everything together, it’s always a good idea to have everythingyou’ll need to get the Router up and running. Depending upon how you con-figure the Router in Chapter 6: The Router’s Web-based Utility, you may needsome of the following values from your ISP:When connecting through a Static IP connection, be sure to have 1) Yourbroadband-configured PC’s fixed Internet IP Address, 2) Your broadband-configured PC’s Computer Name and Workgroup Name, 3) Your SubnetMask, 4) Your Default Gateway, and 5) Your Primary DNS IP address.When connecting through a PPPoE connection, be sure to have 1) YourPPPoE User Name and 2) Your PPPoE Password.The installation technician from your ISP should have left this information withyou after installing your broadband connection. If not, you can call your ISP torequest the data.Once you have the above values, you can begin the Router’s installation andsetup.Once you are sure that you have the above values on hand, you can begin theInstallation and Setup of the Router.1. Power everything down, including your PCs, your cable or DSL modem andthe Router.2. Connect an Ethernet cable from one of your PC’s Ethernet ports to one of theRouter’s LAN ports. Do the same with all the PCs you wish to connect to theRouter. In addition to accessing the Router through an Ethernet connection, a wire-less connection can be used to access the Router. See the “For WirelessConnections” note that follows these connection instructions.3. Connect another Ethernet cable from your cable or DSL modem to theRouter’s Internet port.4. Connect the Power Adapter (included) to the Router’s Power port and plugthe other end into a power outlet.Before You StartConnecting Your Hardware Together and Booting UpWireless Cable/DSL RouterNetwork Everywhere®Series87
Chapter 4: Configuring the PCsThese instructions will help you configure each of your computers to commu-nicate with the Router.To do this, you will need to configure your PC’s network settings to obtain anIP (or TCP/IP) address automatically. Computers use IP addresses to commu-nicate with each other across a network or the Internet.You will need to know which operating system your computer is running, suchas Windows 98 SE, Millennium, 2000, or XP. You can find out by clicking theStart button and then selecting the Settings option. (If your Start menu does-n’t have a Settings option, you’re running Windows XP. You can select theControl Panel directly from the Start Menu.) Then, click Control Panel anddouble-click the System icon. Click the Cancel button when done.Once you know which Windows operating system you are running, follow thedirections in this step for your computer’s operating system. If you PC is notconfigured with the TCP/IP protocol, you will need to do this for each com-puter you are connecting to the Router.The next few pages tell you, step by step, how to configure your TCP/IP set-tings based on the type of Windows operating system you are using. Onceyou've configured your computers, continue to Chapter 6: The Router’s Web-based Utility.1. Click the Start button, click Settings and open the Control Panel. Fromthere, double-click the Network icon to open the Network screen.OverviewConfiguring Windows 98 SE and Millennium PCs• The Power LED will illuminate green as soon as the power adapter is con-nected.• The Diag LED will illuminate red for a few seconds while the Routergoes through its internal diagnostic test. The LED will turn off when theself-test is complete.5. Power on the cable or DSL modem. Verify that the power is on by checkingthe Link LED in the Internet column on the front of the Router. The LinkLED will be illuminated if the power is on and the modem is ready.6. Press the Reset button on the back of the Router. Hold the button in for threeseconds, or until the Diag LED illuminates red. This restores the Router’sdefault settings.7. Power on your PC.The Router is now connected.Continue to the next chapter to configure your PCs.For Wireless Connections: In addition to accessing the Router through anEthernet connection, a wireless connection can be used to access the Router.After powering on the Router and connecting it to your modem, enter theRouter’s IP Address in the Address field of your wireless PC’s web-browser asfollows: http://192.168.1.1 and press Enter.Important:The Router is configured by default to work out of the boxwith all Network Everywhere Wireless Adapters. If you havechanged the defaults on your Network Everywhere WirelessAdapters, or are using other wireless adapters, you must temporar-ily change your wireless adapter settings to: (SSID = wireless) inorder to initially access the Router wirelessly. After you haveaccessed the Router with the default settings, you can change theRouter’s settings to coincide with your Network settings and resetyour adapters.Important:Some ISPs—most notably some cable providers—con-figure their networks so that you do not have to enter a full Internetaddress into your web browser or e-mail application to reach yourhome page or receive your e-mail. If your Internet home pageaddress is something very simple, such as “www”, rather than“www.networkeverywhere.com”, or your e-mail server’s address issomething similar to “e-mail” or “pop3”, rather than “pop.mail.net-workeverywhere.com”, you won’t be able to properly configure theRouter until you determine the actual Internet addresses of yourWeb and e-mail connections.You must obtain this information prior to connecting the Router toyour network. You can obtain this information by contacting your ISP.Wireless Cable/DSL RouterNetwork Everywhere®Series109

Wireless Cable/DSL Router42Network Everywhere®Series41The Preset Applications at the top of the list are among the most widely usedInternet applications. They include the following:•FTP (File Transfer Protocol) A protocol used to transfer files over aTCP/IP network (Internet, UNIX, etc.). For example, after developing theHTML pages for a website on a local machine, web developers typicallyupload the files to the web server using FTP. FTP includes functions to logonto the network, list directories, and copy files. FTP operations can be per-formed by typing commands at a command prompt or via an FTP utilityrunning under a graphical interface such as Windows. FTP transfers canalso be initiated from within a web browser by entering the URL precededby ftp://.•Telnet A terminal emulation protocol commonly used on Internet andTCP/IP-based networks. It allows a user at a terminal or computer to logonto a remote device and run a program.•SMTP (Simple Mail Transfer Protocol) The standard e-mail protocol onthe Internet. It is a TCP/IP protocol that defines the message format and themessage transfer agent (MTA), which stores and forwards the mail. •DNS (Domain Name System) The way that Internet domain names arelocated and translated into IP addresses. A domain name is a meaningfuland easy-to-remember “handle” for an Internet address.•TFTP (Trivial File Transfer Protocol) A version of the TCP/IP FTP proto-col that has no directory or password capability.•Finger A UNIX command widely used on the Internet to find out infor-mation about a particular user, such as his or her telephone number, whetherthe user is currently logged on, and the last time the user was logged on. Theperson being “fingered” must have placed his or her profile on the systemin order for the information to be available. Fingering requires entering thefull user@domain address, for example, name@universityname.edu.•HTTP (HyperText Transport Protocol) The communications protocol usedto connect to servers on the World Wide Web. Its primary function is toestablish a connection with a web server and transmit HTML pages to theclient web browser. •POP3 (Post Office Protocol 3) A standard mail server commonly used onthe Internet. It provides a message store that holds incoming e-mail untilusers log on and download it. POP3 is a simple system with little selectivi-ty.

Enter the following data to create a new static route.Destination LAN IP: The Destination LAN IP is the address of the remotenetwork or host to which you want to assign a static route. Enter the IPaddress of the host for which you wish to create a static route here. If youare building a route to an entire network, be sure that the network portionof the IP address is set to 0. For example, the Router’s standard IP addressis 192.168.1.1. Based on this address, the address of the routed network is192.168.1.x, with the last digit “x” determining the Router’s place on thenetwork. Therefore you would enter the IP address 192.168.1.0 if you want-ed to route to the Router’s entire network, rather than just to the Router.Subnet Mask: The Subnet Mask determines which portion of an IPaddress is the network portion, and which portion is the host portion. Take,for example, a network in which the Subnet Mask is 255.255.255.0. Thisdetermines (by using the values 255) that the first three numbers of a net-work IP address identify this particular network, while the last digit (from1 to 254) identifies the specific host.Default Gateway: This IP address should be the IP address of the gatewaydevice that allows for contact between the Router and the remote networkor host.Hop Count: This determines the maximum number of steps between net-work nodes that data packets will travel. A node is any device on the net-work, such as PCs, print servers, routers, etc. The maximum metric, ormeasure, of hops is 15.Interface: Select LAN or WA N , depending on the location of the staticroute’s final destination.To apply any of the settings you’ve changed on this page, click the Apply but-ton, and then click the Continue button.

This value should remain at its default setting of 2,346.Should you encounter inconsistent data flow, only minor modifications arerecommended.• Fragmentation Threshold. This value indicates how much of the Router’sresources are devoted to recovering packet errors. The value should remainat its default setting of 2,346. If you have decreased this value and experi-ence high packet error rates, you can increase it again, but it will likelydecrease overall network performance. Only minor modifications of thisvalue are recommended.• DTIM Interval. This value indicates the interval of the Delivery TrafficIndication Message (DTIM). A DTIM field is a countdown field informingclients of the next window for listening to broadcast and multicast mes-sages. When the Router has buffered broadcast or multicast messages forassociated clients, it sends the next DTIM with a DTIM Interval value.Clients for the Router hear the beacons and awaken to receive the broadcastand multicast messages.• Basic Rates. The basic transfer rates should be set depending on the speedof your wireless network. You must select 1-2 (Mbps) if you have older802.11 compliant equipment on your network, such as wireless adaptersthat support only 1 or 2 Mbps. Selecting 1-2 (Mbps), however, does notlimit the basic transfer rates of faster adapters.• TX Rates. Select all the rate at which you wish the Router to communicatewithin your wireless network. • Preamble Type. The preamble defines the length of the CRC block forcommunication between the Router and the roaming Network Card. (Highnetwork traffic areas should use the shorter preamble type.) Select theappropriate preamble type and click the Apply button to set it.• Authentication Type. You may choose between Open System,SharedKey, and Both. The Authentication Type default is set to Open System, inwhich the sender and the recipient do NOT share a secret key. Each partygenerates its own key-pair and asks the receiver to accept the randomly-generated key. Once accepted, this key is used for a short time only. Thena new key is generated and agreed upon. Shared Key is when both thesender and the recipient share a secret key.53

Wireless Cable/DSL Router60Network Everywhere®Series59Change the IP address for the Router to another subnet to avoid a conflictbetween the VPN IP address and your local IP address. For example, if yourVPN server assigns an IP address 192.168.1.X (X is a number from 1 to 254)and your local LAN IP address is 192.168.1.X (X is the same number used inthe VPN IP address), the Router will have difficulties routing information tothe right location. If you change the Router’s IP address to 192.168.2.1, thatshould solve the problem. Change the Router’s IP address through the Setup tabof the web interface. If you assigned a static IP address to any computer or net-work device on the network, you need to change its IP address accordingly to192.168.2.Y (Y being any number from 1 to 254). Note that each IP addressmust be unique within the network.Your VPN may require port 500/UDP packets to be passed to the computer thatis connecting to the IPSec server. Refer to “Problem #7, I need to set up onlinegame hosting or use other Internet applications” for details. Check the Network Everywhere website for more information at www.net-workeverywhere.com.6. I need to set up a server behind my Router.To use a server like a web, ftp, or mail server, you need to know the respectiveport numbers they are using. For example, port 80 (HTTP) is used for web;port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and port 110(POP3 incoming) are used for the mail server. You can get more informationby viewing the documentation provided with the server you installed. Followthese steps to set up port forwarding through the Router’s web-based utility. Wewill be setting up web, ftp, and mail servers.A. Access the Router’s web-based utility by going to http://192.168.1.1 or theIP address of the Router. Go to the Advanced => Forwarding tab. B. Enter any name you want to use for the Customized Application.C. Enter the Ext. Port range of the service you are using. For example, if youhave a web server, you would enter the range 80 to 80. D. Check the protocol you will be using, TCP and/or UDP. E. Enter the IP address of the PC or network device that you want the portserver to go to. For example, if the web server’s Ethernet adapter IP addressis 192.168.1.100, you would enter 100 in the field provided. Check“Appendix D: Finding the MAC Address and IP Address for Your EthernetAdapter” for details on getting an IP address.C. Make sure you are using the right Internet settings. Contact your ISP to seeif your Internet connection type is DHCP, Static IP Address, or PPPoE(commonly used by DSL consumers). Please refer to the Setup section of“Chapter 6: The Router’s Web-based Utility” for details on Internet settings.D. Make sure you have the right cable. Check to see if the Internet column hasa solidly lit Link LED. E. Make sure the cable connecting from your cable or DSL modem is con-nected to the Router’s Internet port. Verify that the Status page of theRouter’s web interface shows a valid IP address from your ISP.F. Turn off the computer, Router, and cable/DSL modem. Wait 30 seconds,and then turn on the Router, cable/DSL modem, and computer. Check theStatus tab of the Router’s web-based utility to see if you get an IP address. 4. I am not able to access the Router’s web interface Setup page.A. Refer to “Problem #2, I want to test my Internet connection” to verify thatyour computer is properly connected to the Router.B. Refer to “Appendix D: Finding the MAC Address and IP address for YourEthernet Adapter” to verify that your computer has an IP Address, SubnetMask, Gateway, and DNS.C. Set a static IP address on your system; refer to “Problem #1: I need to set astatic IP address.”D. Refer to “Problem #10: I need to remove the proxy settings or the dial-uppop-up window (for PPPoE users).”5. I can’t get my Virtual Private Network (VPN) working through the Router.Access the Router’s web interface by going to http://192.168.1.1 or the IPaddress of the Router, and go to the Advanced => Filter tab. Make sure youhave IPsec pass-through and/or PPTP pass-through enabled.VPNs that use IPSec with the ESP (Encapsulation Security Payload known asprotocol 50) authentication will work fine. At least one IPSec session will workthrough the Router; however, simultaneous IPSec sessions may be possible,depending on the specifics of your VPNs.VPNs that use IPSec and AH (Authentication Header known as protocol 51)are incompatible with the Router. AH has limitations due to occasional incom-patibility with the NAT standard.

I can’t get the Internet game, server, or application to work.If you are having difficulties getting any Internet game, server, or applicationto function properly, consider exposing one PC to the Internet usingDeMilitarized Zone (DMZ) hosting. This option is available when an applica-tion requires too many ports or when you are not sure which port services touse. Make sure you disable all the forwarding entries if you want to success-fully use DMZ hosting, since forwarding has priority over DMZ hosting. (Inother words, data that enters the Router will be checked first by the forwardingsettings. If the port number that the data enters from does not have port for-warding, then the Router will send the data to whichever PC or network deviceyou set for DMZ hosting.) Follow these steps to set DMZ hosting:A. Access the Router’s web-based utility by going to http://192.168.1.1 or theIP address of the Router. Go to the Advanced => Forwarding tab.B. Disable or remove the entries you have entered for forwarding. Keep thisinformation in case you want to use it at a later time.C. Click the DMZ Host tab.D. Enter the Ethernet adapter’s IP address of the computer you want exposedto the Internet. This will bypass the NAT firewall for that computer. Pleaserefer to “Appendix D: Finding the MAC Address and IP Address for YourEthernet Adapter” for details on getting an IP address. Once completed with the configuration, click the Apply button.F. Check the Enable option for the port services you want to use. Consider theexample below:Customized Ext. Port TCP UDP IP Address EnableApplicationWeb server 80 to 80 X X 192.168.1.100 XFTP server 21 to 21 X 192.168.1.101 XSMTP (outgoing)25 to 25 X X 192.168.1.102 XPOP3 (incoming) 110 to 110 X X 192.168.1.102 XWhen you have completed the configuration, click the Apply button.7. I need to set up online game hosting or use other Internet applications.If you want to play online games or use Internet applications, most will workwithout doing any port forwarding or DMZ hosting. There may be cases whenyou want to host an online game or Internet application. This would requireyou to set up the Router to deliver incoming packets or data to a specific com-puter. This also applies to the Internet applications you are using. The best wayto get the information on what port services to use is to go to the website of theonline game or application you want to use. Follow these steps to set up onlinegame hosting or use a certain Internet application:A. Access the Router’s web interface by going to http://192.168.1.1 or the IPaddress of the Router. Go to the Advanced => Forwarding tab.B. Enter any name you want to use for the Customized Application.C. Enter the Ext. Port range of the service you are using. For example, if youwant to host Unreal Tournament (UT), you would enter the range 7777 to27900.D. Check the protocol you will be using, TCP and/or UDP. E. Enter the IP address of the PC or network device that you want the portserver to go to. For example, if the web server’s Ethernet adapter IP addressis 192.168.1.100, you would enter 100 in the field provided. Check“Appendix D: Finding the MAC Address and IP Address for Your EthernetAdapter” for details on getting an IP address.

Youcan also use a port forwarding range of 7777 ~ 27900. If you want to use theUT Server Admin, forward another port (8080 usually works well but is usedfor remote admin. You may have to disable this.), and then in the[UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (tomatch the mapped port above) and ServerName to the IP assigned to theRouter from your ISP.Can multiple gamers on the LAN get on one game server and play simultaneouslywith just one public IP address? It depends on which network game or whatkind of game server you are using. For example, Unreal Tournament supportsmulti-login with one public IP.How do I get Half-Life: Team Fortressto work with the Router? The default clientport for Half-Life is 27005. The computers on your LAN need to have“+clientport 2700x” added to the HL shortcut command line; the x would be6, 7, 8, and on up. This lets multiple computers connect to the same server.One problem: Version 1.0.1.6 won’t let multiple computers with the same CDkey connect at the same time, even if on the same LAN (not a problem with1.0.1.3). As far as hosting games, the HL server does not need to be in theDMZ. Just forward port 27015 to the local IP address of the server comput-er. The web page hangs; downloads are corrupt, or nothing but junk characters arebeing displayed on the screen. What do I need to do? Force your Ethernetadapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate”feature of your Ethernet adapter as a temporary measure. (Please look at theNetwork Control Panel in your Ethernet adapter’s Advanced Properties tab.)Make sure that your proxy setting is disabled in the browser. Check our web-site at www.linksys.com for more information.If all else fails in the installation, what can I do? Reset the Router by holdingdown the reset button for about 30 seconds. Reset your cable or DSL modemby powering the unit off and then on. Obtain and flash the latest firmwarerelease that is readily available on the Network Everywhere website,www.networkeverywhere.com.What is the maximum number of IP addresses that the Router will support? TheRouter will support up to 253 IP addresses.Is IPSec Pass-Through supported by the Router? Yes, it is a built-in feature thatthe Router automatically enables.Where is the Router installed on the network? In a typical environment, theRouter is installed between the cable/DSL modem and the LAN. Plug theRouter into the cable/DSL modem’s Ethernet port.Does the Router support IPX or AppleTalk? No. TCP/IP is the only protocol stan-dard for the Internet and has become the global standard for communications.IPX, a NetWare communications protocol used only to route messages fromone node to another, and AppleTalk, a communications protocol used onApple and Macintosh networks, can be used for LAN to LAN connections,but those protocols cannot connect from Internet to LAN.Does the Router’s Internet port support 100 Mbps Ethernet? Because of the speedlimitations of broadband Internet connections, the Router’s current hardwaredesign supports 10 Mbps Ethernet on its Internet port. It does, of course, sup-port 100 Mbps over its LAN ports. What is Network Address Translation and what is it used for? Network AddressTranslation (NAT) translates multiple IP addresses on the private LAN to onepublic address that is sent out to the Internet. This adds a level of securitysince the address of a PC connected to the private LAN is never transmittedon the Internet. Furthermore, NAT allows the Router to be used with low costInternet accounts, such as DSL or cable modems, when only one TCP/IPaddress is provided by the ISP. The user may have many private addressesbehind this single address provided by the ISP.Does the Router support any operating system other than Windows 98 SE,Windows 2000, Windows NT, or Windows XP? Yes, but Network Everywheredoes not, at this time, provide technical support for setup, configuration ortroubleshooting of any non-Windows operating systems.Does the Router support ICQ send file? Yes, with the following fix: click ICQmenu -> preference -> connections tab->, and check I am behind a fire-wall or proxy. Then set the firewall time-out to 80 seconds in the firewall set-Frequently Asked Questions

Makesure that your browser is set to connect directly and that any dial-up is dis-abled. For Internet Explorer, click Tools,Internet Options, and then theConnection tab. Make sure that Internet Explorer is set to Never dial a con-nection. For Netscape Navigator, click Edit,Preferences,Advanced, andProxy. Make sure that Netscape Navigator is set to Direct connection to theInternet.What is DMZ Hosting? Demilitarized Zone (DMZ) allows one IP address (com-puter) to be exposed to the Internet. Some applications require multipleTCP/IP ports to be open. It is recommended that you set your computer witha static IP if you want to use DMZ Hosting. To get the LAN IP address, see“Appendix D: Finding the MAC Address and IP Address for Your EthernetAdapter.”If DMZ Hosting is used, does the exposed user share the public IP with the Router?No.Does the Router pass PPTP packets or actively route PPTP sessions? The Routerallows PPTP packets to pass through.
Wireless Cable/DSL RouterHopping Spread Spectrum (FHSS) uses a narrowband carrier that changesfrequency in a pattern that is known to both transmitter and receiver. Properlysynchronized, the net effect is to maintain a single logical channel. To anunintended receiver, FHSS appears to be short-duration impulse noise. DirectSequence Spread Spectrum (DSSS) generates a redundant bit pattern for eachbit to be transmitted. This bit pattern is called a chip (or chipping code). Thelonger the chip, the greater the probability that the original data can be recov-ered. Even if one or more bits in the chip are damaged during transmission,statistical techniques embedded in the radio can recover the original datawithout the need for retransmission. To an unintended receiver, DSSS appearsas low power wideband noise and is rejected (ignored) by most narrowbandreceivers. Would the information be intercepted while transmitting on air? WLAN featurestwo-fold protection in security. On the hardware side, as with DirectSequence Spread Spectrum technology, it has the inherent security feature ofscrambling. On the software side, the WLAN series offers the encryptionfunction (WEP) to enhance security and access control. Users can set it updepending upon their needs.What is WEP? WEP is Wired Equivalent Privacy, a data privacy mechanismbased on a 40/64 bit shared key algorithm, as described in the IEEE 802.11standard.What is a MAC Address? The Media Access Control (MAC) address is a uniquenumber assigned by the manufacturer to any Ethernet networking device,such as a network adapter, that allows the network to identify it at the hard-ware level. For all practical purposes, this number is usually permanent.Unlike IP addresses, which can change every time a computer logs on to thenetwork, the MAC address of a device stays the same, making it a valuableidentifier for the network.If your questions are not addressed here,refer to the Network Everywhere website,www.networkeverywhere.com.72Network Everywhere®SeriesWhat IEEE 802.11 features are supported? The product supports the followingIEEE 802.11 functions: • CSMA/CA plus Acknowledge protocol • Multi-Channel Roaming• Automatic Rate Selection • RTS/CTS feature • Fragmentation • Power Management What is BSS ID? A specific Ad-hoc LAN is called a Basic Service Set (BSS).Computers in a BSS must be configured with the same BSS ID.What is SSID? An Infrastructure configuration could also support roamingcapability for mobile workers. More than one BSS can be configured as anExtended Service Set (ESS). Users within an ESS could roam freely betweenBSSs while maintaining a continuous connection to the wireless network sta-tions and Access Points.What is ISM band? The FCC and their counterparts outside of the U.S. have setaside bandwidth for unlicensed use in the ISM (Industrial, Scientific andMedical) band. This presents a truly revolutionary opportunity to place con-venient high speed wireless capabilities in the hands of users around theglobe.What is Spread Spectrum? Spread Spectrum technology is a wideband radio fre-quency technique developed by the military for use in reliable, secure, mis-sion-critical communications systems. It is designed to trade off bandwidthefficiency for reliability, integrity, and security. In other words, more band-width is consumed than in the case of narrowband transmission, but the trade-off produces a signal that is, in effect, louder and thus easier to detect, pro-vided that the receiver knows the parameters of the spread-spectrum signalbeing broadcast. If a receiver is not tuned to the right frequency, a spread-spectrum signal looks like background noise. There are two main variations,Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping SpreadSpectrum (FHSS).What is DSSS? What is FHSS? And what are their differences? Frequency71
Wireless Cable/DSL Router74Network Everywhere®Series733. At the DOS command prompt, type “ping mail” (assuming that the loca-tion for which you’re trying to find an IP address is configured as “mail”).Press Enter. Information such as the following data, taken from a ping ofMicrosoft Network’s e-mail server, will be displayed.4. Write down the IP address returned by the ping command. (In theexample above: 24.53.32.4.) This IP address is the actual IP address of theserver “mail,” or any other word or value you have pinged.Step Two: Pinging for a Web AddressWhile the IP address returned above would work as your e-mail server address,it may not be permanent. IP addresses change all the time. Web addresses, how-ever, usually don’t. Because of this, you’re likely to have fewer problems byconfiguring your system with web addresses rather than IP addresses. Followthe instructions below to find the web address assigned to the IP address youjust pinged.1. At the DOS command prompt, type “ping -a 24.53.32.4,” where24.53.32.4 is the IP address you just pinged. Information such as the fol-lowing data will be displayed.C:\>ping mailPinging mail [24.53.32.4] with 32 bytes of data:Reply from 24.53.32.4: bytes=32 time<10ms TTL=128Reply from 24.53.32.4: bytes=32 time<10ms TTL=128Reply from 24.53.32.4: bytes=32 time<10ms TTL=128Reply from 24.53.32.4: bytes=32 time<10ms TTL=128Ping statistics for 24.53.32.4:Packets: Sent = 4, Received = 4, Lost = 0 (0%loss),Approximate round trip times in milli-seconds:Minimum = 0ms, Maximum = 0ms, Average = 0msAppendix B: How to Ping Your ISP’sE-mail and Web AddressesVirtually all Internet addresses are configured with words or characters (i.e.,www.networkeverywhere.com, www.yahoo.com, etc.) In actuality, however,these Internet addresses are assigned to IP addresses, which are the trueaddresses on the Internet.IP and web addresses, however, can sometimes be long and hard to remember.Because of this, certain ISPs will shorten their server addresses to single wordsor codes on their users’ web browser or e-mail configurations. If your ISP’s e-mail and web server addresses are configured with single words (“www,” “e-mail,” “home,” “pop3,” etc.) rather than whole Internet Addresses or IPAddresses, the Router may have problems sending or receiving mail andaccessing the Internet. This happens because the Router has not been config-ured by your ISP to accept their abbreviated server addresses.The solution is to determine the true web addresses behind your ISP’s codewords. You can determine the IP and web addresses of your ISP’s servers by“pinging” them.Step One: Pinging an IP AddressThe first step to determining your ISP’s web and e-mail server address is toping its IP address.1. Power on the computer and the cable or DSL modem, and restore thenetwork configuration set by your ISP if you have since changed it.2. Click Start, then Run, and type “command.” This will bring up the DOSwindow.Note: If you don’t have your ISP’s web and e-mail IP addresses, you musteither get them from your ISP or follow these steps prior to connecting theRouter to your network.
Wireless Cable/DSL Router76Network Everywhere®Series75Appendix C: Configuring WirelessSecurityAn acronym for Wired Equivalent Privacy, WEP is an encryption method usedto protect your wireless data communications. WEP uses a combination of 64-bit or 128-bit keys to provide access control to your network and encryptionsecurity for every data transmission. To decode a data transmission, each pointin a network must use an identical 64-bit or 128-bit key. Higher encryption lev-els mean higher levels of security, but due to the complexity of the encryption,they may mean decreased network performance.You may also have heard the term “40-bit” used in conjunction with WEPencryption. This is simply another term for 64-bit WEP encryption. This levelof WEP encryption has been called 40-bit because it uses a 40-bit secret keyalong with a 24-bit Initialization Vector (40 + 24 = 64). Wireless vendors mayuse either name. Network Everywhere uses the term “64-bit” when referringto this level of encryption.Make sure your wireless network is functioning before attempting to configureWEP encryption.A 128-bit WEP encrypted wireless network will NOT communicate with a 64-bit WEP encrypted wireless network. Therefore, make sure that all of yourwireless devices are using the same encryption level. All wireless devices com-plying with the 802.11b standard will support 64-bit WEP.In addition to enabling WEP, Network Everywhere also recommends the fol-lowing security implementations:•Changing the SSID from the default “wireless”•Changing the WEP key regularlyNote: WEP encryption is an additional data securi-ty measure and not essential for router operation.Note: In order for WEP Encryption to be enabled, wireless functions mustfirst be enabled. Select Enable under the Wireless section before proceeding.2. Write down the web address returned by the ping command (in theexample above: mail.msnv3.occa.home.com.). This web address is the webaddress assigned to the IP address you just pinged. While the IP address of“mail” could conceivably change, it is likely that this web address will not.3. Replace your ISP’s abbreviated server address with this extended webaddress in the corresponding Internet application (web browser, e-mailapplication, etc.).Once you have replaced the brief server address with the true server address,the Router should have no problem accessing the Internet through that Internetapplication.C:\>ping -a 24.53.32.4Pinging mail.msnv3.occa.home.com [24.53.32.4] with32 bytes of data:Reply from 24.53.32.4: bytes=32 time<10ms TTL=127Reply from 24.53.32.4: bytes=32 time<10ms TTL=127Reply from 24.53.32.4: bytes=32 time<10ms TTL=127Reply from 24.53.32.4: bytes=32 time<10ms TTL=127Ping statistics for 24.53.32.4:Packets: Sent = 4, Received = 4, Lost = 0 (0%loss),Approximate round trip times in milli-seconds:Minimum = 0ms, Maximum = 0ms, Average = 0ms
Wireless Cable/DSL Router78Network Everywhere®Series77• WEP (64Bit or 128B) Select the level of encryption from the drop-downbox. 128-bit WEP encryption is unique to Network Everywhere and mayconflict with other vendors’ WEP encryption.The WEP Encryption key is generated in one of two ways:1. You may create an encryption key by using a Passphrase.a. Enter a Passphrase, a user-defined password, into the Passphrase field.The Passphrase can be a maximum of 31 letters, symbols, and numbers.No spaces can be used.b. Click the Generate button to create a key. The key will be 10 digits ifyou chose 64-bit encryption, or 26 digits if you chose 128-bit encryption.This key will be used to encrypt and decrypt the data being sent betweenthe Router and your network’s wireless PCs.The Key field may not display all digits. Using the mouse, click any-where within the Key field. Move the cursor to the right to view the restof the Key. Make sure your write down the entire Key EXACTLY theway it is displayed. 2. You may enter the encryption key manually.Make a note of the Passphrase or Manual Key. You will need it for the otherwireless devices on the network, as the same WEP encryption key must beentered in all wireless devices on the network.Once you have chosen your key encryption method and entered either thePassphrase or manual key, click the Apply button, and the encryption portionof the setup is complete.Note: In order to utilize WEP encryption, all points in your wirelessnetwork must have WEP enabled and be set to the same Key Setting.Note: In Windows XP, a 128-bit Key generated by the Routerwill be called a "104 bits (26 digits)" key, and a 64-bit Key gen-erated by the Router will be called a “40 bits (10 digits)” key.The following steps will show you how to utilize WEP encryption1. From the Web-based Utility’s Setup tab, select Mandatory under the WEPsection.2. Press the WEP Key Setting button to set the WEP Encryption type andlevel.3.

Wireless Cable/DSL Router88Network Everywhere®Series87Appendix E: Glossary10BaseT - An Ethernet standard that uses twisted wire pairs.100BaseTX - IEEE physical layer specification for 100 Mbps over two pairs ofCategory 5 cable.Adapter - Printed circuit board that plugs into a PC to add to capabilities orconnectivity to a PC. In a networked environment, a network interface card isthe typical adapter that allows the PC or server to connect to the intranet and/orInternet.Auto-negotiate - To automatically determine the correct settings. The term isoften used with communications and networking. For example, Ethernet10/100 cards and switches can determine the highest speed of the node they areconnected to and adjust their transmission rate accordingly.Bandwidth - The transmission capacity of a given facility, in terms of howmuch data the facility can transmit in a fixed amount of time; expressed in bitsper second (bps).Bit – A binary digit. The value—0 or 1—used in the binary numbering system.Also, the smallest form of data.Boot – To cause the computer to start executing instructions. Personal comput-ers contain built-in instructions in a ROM chip that are automatically executedon startup. These instructions search for the operating system, load it, and passcontrol to it. Bridge - A device that interconnects different networks together. Broadband - A data-transmission scheme in which multiple signals share thebandwidth of a medium. This allows the transmission of voice, data, and videosignals over a single medium. Cable television uses broadband techniques todeliver dozens of channels over one cable.Browser - A browser is an application program that provides a way to look atand interact with all the information on the World Wide Web or PC. The word“browser” seems to have originated prior to the Web as a generic term for userinterfaces that let you browse text files online. Cable Modem - A device that connects a computer to the cable television net-work, which in turn connects to the Internet. Once connected, cable modemusers have a continuous connection to the Internet. Cable modems featureWhen entering the information using the Router’s web-based utility, you willtype the 12-digit MAC address in this format, XXXXXXXXXXXX withoutthe hyphens for MAC Filtering. See Figure D-6.When entering information for MAC Address Cloning, type the 12-digit MACaddress (see Figure D-7). Figure D-6Figure D-7
Wireless Cable/DSL RouterDHCP supports static addresses for computers containing Web servers thatneed a permanent IP address. DMZ - (DeMilitarized Zone) allows one IP address (or computer) to beexposed to the Internet. Some applications require multiple TCP/IP ports to beopen. It is recommended that you set your computer with a static IP address ifyou want to use DMZ Hosting.DNS - The Domain Name System (DNS) is the way that Internet domainnames are located and translated into Internet Protocol (IP) addresses. Adomain name is a meaningful and easy-to-remember “handle” for an Internetaddress.Domain - A subnetwork comprised of a group of clients and servers under thecontrol of one security database. Dividing LANs into domains improves per-formance and security.Download - To receive a file transmitted over a network. In a communicationssession, download means receive, and upload means transmit. Dynamic IP Address - An IP address that is automatically assigned to a clientstation in a TCP/IP network, typically by a DHCP server. Network devices thatserve multiple users, such as servers and printers, are usually assigned static IPaddresses.Dynamic Routing - The ability for a router to forward data via a different routebased on the current conditions of the communications circuits. For example,it can adjust for overloaded traffic or failing lines and is much more flexiblethan static routing, which uses a fixed forwarding path.Ethernet - IEEE standard network protocol that specifies how data is placedon and retrieved from a common transmission medium. Has a transfer rate of10 Mbps. Forms the underlying transport vehicle used by several upper-levelprotocols, including TCP/IP and XNS.Firewall - A firewall is a set of related programs, located at a network gatewayserver, that protects the resources of a network from users from other networks.(The term also implies the security policy that is used with the programs.) Anenterprise with an intranet that allows its workers access to the wider Internetinstalls a firewall to prevent outsiders from accessing its own private dataresources and for controlling what outside resources to which its own usershave access. Basically, a firewall, working closely with a router, examines each networkpacket to determine whether to forward it toward its destination.90Network Everywhere®Seriesasymmetric transfer rates: around 36 Mbps downstream (from the Internet tothe computer), and from 200 Kbps to 2 Mbps upstream (from the computer tothe Internet).CAT 5 - ANSI/EIA (American National Standards Institute/ElectronicIndustries Association) Standard 568 is one of several standards that specify“categories” (the singular is commonly referred to as “CAT”) of twisted paircabling systems (wires, junctions, and connectors) in terms of the data ratesthat they can sustain. CAT 5 cable has a maximum throughput of 100 Mbps andis usually utilized for 100BaseTX networks.CSMA/CD (Carrier Sense Multiple Access/Collision Detection) - The LANaccess method used in Ethernet. When a device wants to gain access to the net-work, it checks to see if the network is quiet (senses the carrier). If it is not, itwaits a random amount of time before retrying. If the network is quiet and twodevices access the line at exactly the same time, their signals collide. When thecollision is detected, they both back off and each waits a random amount oftime before retrying. Data Packet - One frame in a packet-switched message. Most data communi-cations is based on dividing the transmitted message into packets. For example,an Ethernet packet can be from 64 to 1518 bytes in length.Default Gateway - The routing device used to forward all traffic that is notaddressed to a station within the local subnet.DHCP (Dynamic Host Configuration Protocol) - A protocol that lets networkadministrators centrally manage and automate the assignment of InternetProtocol (IP) addresses in an organization's network. Using the Internet’s set ofprotocol (TCP/IP), each machine that can connect to the Internet needs aunique IP address. When an organization sets up its computer users with a con-nection to the Internet, an IP address must be assigned to each machine.Without DHCP, the IP address must be entered manually at each computer and,if computers move to another location in another part of the network, a new IPaddress must be entered. DHCP lets a network administrator supervise and dis-tribute IP addresses from a central point and automatically sends a new IPaddress when a computer is plugged into a different place in the network. DHCP uses the concept of a “lease” or amount of time that a given IP addresswill be valid for a computer. The lease time can vary depending on how long auser is likely to require the Internet connection at a particular location. It’s espe-cially useful in education and other environments where users change fre-quently. Using very short leases, DHCP can dynamically reconfigure networksin which there are more computers than there are available IP addresses. 89

IP Address - In the most widely installed level of the Internet Protocol (IP)today, an IP address is a 32-binary digit number that identifies each sender orreceiver of information that is sent in packets across the Internet. When yourequest an HTML page or send e-mail, the Internet Protocol part of TCP/IPincludes your IP address in the message (actually, in each of the packets if morethan one is required) and sends it to the IP address that is obtained by lookingup the domain name in the Uniform Resource Locator you requested or in thee-mail address you're sending a note to. At the other end, the recipient can seethe IP address of the Web page requestor or the e-mail sender and can respondby sending another message using the IP address it received. IPCONFIG - A utility that provides for querying, defining and managing IPaddresses within a network. A commonly used utility, under Windows NT and2000, for configuring networks with static IP addresses.IPSec (Internet Protocol Security) - IPSec is a developing standard for securi-ty at the network or packet processing layer of network communication. A bigadvantage of IPSec is that security arrangements can be handled withoutrequiring changes to individual user computers. ISP - An ISP (Internet service provider) is a company that provides individualsand companies access to the Internet and other related services such as websitebuilding and virtual hosting. LAN - A local area network (LAN) is a group of computers and associateddevices that share a common communications line and typically share theresources of a single processor or server within a small geographic area (forexample, within an office building). Latency - The time delay between when the first bit of a packet is received andthe last bit is forwarded.MAC Address - The MAC (Media Access Control) address is a unique num-ber assigned by the manufacturer to any Ethernet networking device, such as anetwork adapter, that allows the network to identify it at the hardware level.Firmware - Code that is written onto read-only memory (ROM) or program-mable read-only memory (PROM). Once firmware has been written onto theROM or PROM, it is retained even when the device is turned off.Fragmentation - Breaking a packet into smaller units when transmitting overa network medium that cannot support the original size of the packet. FTP (File Transfer Protocol) - A protocol used to transfer files over a TCP/IPnetwork (Internet, UNIX, etc.). For example, after developing the HTML pagesfor a website on a local machine, they are typically uploaded to the Web serv-er using FTP.FTP includes functions to log onto the network, list directories, and copy files.It can also convert between the ASCII and EBCDIC character codes. FTP oper-ations can be performed by typing commands at a command prompt or via anFTP utility running under a graphical interface such as Windows. FTP transferscan also be initiated from within a Web browser by entering the URL precededwith ftp://.Unlike e-mail programs in which graphics and program files have to be“attached,” FTP is designed to handle binary files directly and does not add theoverhead of encoding and decoding the data.Full Duplex - The ability of a device or line to transmit data simultaneously inboth directions.Gateway – A device that interconnects networks with different, incompatiblecommunications protocols. Half Duplex - Data transmission that can occur in two directions over a singleline, but only one direction at a time.Hardware - Hardware is the physical aspect of computers, telecommunica-tions, and other information technology devices. The term arose as a way to dis-tinguish the “box” and the electronic circuitry and components of a computerfrom the program you put in it to make it do things. The program came to beknown as the software.HTTP (HyperText Transport Protocol) - The communications protocol usedto connect to servers on the World Wide Web. Its primary function is to estab-lish a connection with a Web server and transmit HTML pages to the clientbrowser.IEEE - The Institute of Electrical and Electronics Engineers. The IEEEdescribes itself as “the world's largest technical professional society—promot-
Wireless Cable/DSL RouterRIP (Routing Information Protocol) - A simple routing protocol that is part ofthe TCP/IP protocol suite. It determines a route based on the smallest hop countbetween source and destination. RIP is a distance vector protocol that routine-ly broadcasts routing information to its neighboring routers.RJ-45 - A connector similar to a telephone connector that holds up to eightwires, used for connecting Ethernet devices.Router - Protocol-dependent device that connects subnetworks together.Routers are useful in breaking down a very large network into smaller subnet-works; they introduce longer delays and typically have much lower throughputrates than bridges. Server - Any computer whose function in a network is to provide user accessto files, printing, communications, and other services. SMTP (Simple Mail Transfer Protocol) - The standard e-mail protocol on theInternet. It is a TCP/IP protocol that defines the message format and the mes-sage transfer agent (MTA), which stores and forwards the mail.SNMP (Simple Network Management Protocol) - A widely used networkmonitoring and control protocol. Data is passed from SNMP agents, which arehardware and/or software processes reporting activity in each network device(switch, router, bridge, etc.) to the workstation console used to oversee the net-work. The agents return information contained in a MIB (ManagementInformation Base), which is a data structure that defines what is obtainablefrom the device and what can be controlled (turned off, on, etc.).Software - Instructions for the computer. A series of instructions that performsa particular task is called a “program.” The two major categories of software are“system software” and “application software.” System software is made up ofcontrol programs such as the operating system and database management sys-tem (DBMS). Application software is any program that processes data for theuser.A common misconception is that software is data. It is not. Software tells thehardware how to process the data.Static IP Address - A permanent IP address that is assigned to a node in aTCP/IP network. Static Routing - Forwarding data in a network via a fixed path. Static routingcannot adjust to changing line conditions as can dynamic routing. 94Network Everywhere®Series93Mbps (MegaBits Per Second) - One million bits per second; unit of measure-ment for data transmission.mIRC - mIRC runs under Windows and provides a graphical interface for log-ging onto IRC servers and listing, joining, and leaving channels.NAT - NAT (Network Address Translation) is the translation of an InternetProtocol address (IP address) used within one network to a different IP addressknown within another network. One network is designated the inside networkand the other is the outside. Network - A system that transmits any combination of voice, video, and/ordata between users. Packet Filtering - Discarding unwanted network traffic based on its originat-ing address or range of addresses or its type (e-mail, file transfer, etc.). Ping (Packet INternet Groper) - An Internet utility used to determine whethera particular IP address is online. It is used to test and debug a network by send-ing out a packet and waiting for a response.POP3 (Post Office Protocol 3) - A standard mail server commonly used on theInternet. It provides a message store that holds incoming e-mail until users logon and download it. POP3 is a simple system with little selectivity. All pendingmessages and attachments are downloaded at the same time. POP3 uses theSMTP messaging protocol.Port - A pathway into and out of the computer or a network device such as aswitch or router. For example, the serial and parallel ports on a personal com-puter are external sockets for plugging in communications lines, modems, andprinters.PPPoE (Point to Point Protocol over Ethernet) - PPPoE is a method for theencapsulation of PPP packets over Ethernet frames from the user to the ISPover the Internet. One reason PPPoE is preferred by ISPs is because it providesauthentication (username and password) in addition to data transport. A PPPoEsession can be initiated by either a client application residing on a PC, or byclient firmware residing on a modem or router.PPTP (Point-to-Point Tunneling Protocol) - A protocol which allows the Pointto Point Protocol (PPP) to be tunneled through an IP network. PPTP does notspecify any changes to the PPP protocol but rather describes a “tunneling serv-ice” for carrying PPP (a tunneling service is any network service enabled bytunneling protocols such as PPTP, L2F, L2TP, and IPSEC tunnel
Wireless Cable/DSL Routerthe actual delivery of the data (routing), UDP takes care of keeping track of theindividual units of data (called packets) that a message is divided into for effi-cient delivery over the network. UDP is known as a “connection-less” protocoldue to NOT requiring the receiver of a packet to return an acknowledgment ofreceipt to the sender of the packet (as opposed to TCP).Upgrade - To replace existing software or firmware with a newer version. Upload - To send a file transmitted over a network. In a communications ses-sion, upload means transmit, and download means receive. URL (Uniform Resource Locator) - The address that defines the route to a fileon the Web or any other Internet facility. URLs are typed into the browser toaccess Web pages, and URLs are embedded within the pages themselves to pro-vide the hypertext links to other pages.WAN (Wide Area Network) - A communications network that covers a rela-tively large geographic area, consisting of two or more LANs. Broadband com-munication over the WAN is often through public networks such as the tele-phone (DSL) or cable systems, or through leased lines or satellites. In its mostbasic definition, the Internet could be considered a WAN.WINIPCFG - Configuration utility based on the Win32 API for querying,defining, and managing IP addresses within a network. A commonly used util-ity for configuring networks with static IP addresses.Workgroup - Two or more individuals that share files and databases. 96Network Everywhere®SeriesSubnet Mask - The method used for splitting IP networks into a series of sub-groups, or subnets. The mask is a binary pattern that is matched up with the IPaddress to turn part of the host ID address field into a field for subnets. Switch – 1. A data switch connects computing devices to host computers,allowing a large number of devices to share a limited number of ports. 2. Adevice for making, breaking, or changing the connections in an electrical cir-cuit.TCP (Transmission Control Protocol) - A method (protocol) used along withthe IP (Internet Protocol) to send data in the form of message units (datagram)between network devices over a LAN or WAN. While IP takes care of handlingthe actual delivery of the data (routing), TCP takes care of keeping track of theindividual units of data (called packets) that a message is divided into for effi-cient delivery over the network. TCP is known as a “connection oriented” pro-tocol due to requiring the receiver of a packet to return an acknowledgment ofreceipt to the sender of the packet resulting in transmission control.TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic com-munication language or set of protocols for communications over a network(developed specifically for the Internet). TCP/IP defines a suite or group ofprotocols and not only TCP and IP.Telnet - A terminal emulation protocol commonly used on the Internet andTCP/IP-based networks. It allows a user at a terminal or computer to log ontoa remote device and run a program.TFTP (Trivial File Transfer Protocol) - A version of the TCP/IP FTP protocolthat has no directory or password capability.Throughput - The amount of data moved successfully from one place to anoth-er in a given time period.Topology - A network’s topology is a logical characterization of how thedevices on the network are connected and the distances between them. Themost common network devices include switches, routers, and gateways. Mostlarge networks contain several levels of interconnection, the most important ofwhich include edge connections, backbone connections, and wide-area con-nections.TX Rate – Transmission Rate.UDP (User Datagram Protocol) - A method (protocol) used along with the IP(Internet Protocol) to send data in the form of message units (datagram)between network devices over a LAN or WAN. While IP takes care of handling95
