Reference Manual for the 54 Mbps Wireless Router WGR614 v52-2 IntroductionJune 2004 202-10036-01• Ethernet connection to a wide area network (WAN) device, such as a cable modem or DSL modem.• Extensive Protocol Support.• Login capability.• Front panel LEDs for easy monitoring of status and activity.• Flash memory for firmware upgrades.802.11g Wireless NetworkingThe WGR614 v5 router includes an 802.11g wireless access point, providing continuous, high-speed 54 Mbps access between your wireless and Ethernet devices. The access point provides:• 802.11g wireless networking at up to 54 Mbps.• 802.11g wireless networking, with the ability to operate in 802.11g-only, 802.11b-only, or 802.11g and b modes, providing backwards compatibility with 802.11b devices or dedicating the wireless network to the higher bandwidth 802.11g devices.• 64-bit and 128-bit WEP encryption security.• WEP keys can be generated manually or by passphrase.• WPA-PSK support. Support for Wi-Fi Protected Access (WPA) data encryption which provides strong data encryption and authentication based on a pre-shared key.• Wireless access can be restricted by MAC address.• Wireless network name broadcast can be turned off so that only devices that have the network name (SSID) can connect.A Powerful, True Firewall with Content FilteringUnlike simple Internet sharing NAT routers, the WGR614 v5 is a true firewall, using stateful packet inspection to defend against hacker attacks. Its firewall features include:• Denial of Service (DoS) protection.Automatically detects and thwarts DoS attacks such as Ping of Death, SYN Flood, LAND Attack, and IP Spoofing.• Blocks unwanted traffic from the Internet to your LAN.• Blocks access from your LAN to Internet locations or services that you specify as off-limits.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Introduction 2-3June 2004 202-10036-01• Logs security incidents.The WGR614 v5 will log security events such as blocked incoming traffic, port scans, attacks, and administrator logins. You can configure the router to E-mail the log to you at specified intervals. You can also configure the router to send immediate alert messages to your E-mail address or E-mail pager whenever a significant event occurs.• The WGR614 v5 prevents objectionable content from reaching your computers. The router allows you to control access to Internet content by screening for keywords within Web addresses. You can configure the router to log and report attempts to access objectionable Internet sites.SecurityThe WGR614 v5 router is equipped with several features designed to maintain security, as described in this section.• Computers Hidden by NATNAT opens a temporary path to the Internet for requests originating from the local network. Requests originating from outside the LAN are discarded, preventing users outside the LAN from finding and directly accessing the computers on the LAN.• Port Forwarding with NATAlthough NAT prevents Internet locations from directly accessing the computers on the LAN, the router allows you to direct incoming traffic to specific computers based on the service port number of the incoming request, or to one designated “DMZ” host computer. You can specify forwarding of single ports or ranges of ports.Autosensing Ethernet Connections with Auto UplinkWith its internal 4-port 10/100 switch, the WGR614 v5 can connect to either a 10 Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. Both the LAN and WAN interfaces are autosensing and capable of full-duplex or half-duplex operation. The router incorporates Auto UplinkTM technology. Each Ethernet port will automatically sense whether the Ethernet cable plugged into the port should have a ‘normal’ connection such as to a computer or an ‘uplink’ connection such as to a switch or hub. That port will then configure itself to the correct configuration. This feature also eliminates the need to worry about crossover cables, as Auto Uplink will accommodate either type of cable to make the right connection.
Reference Manual for the 54 Mbps Wireless Router WGR614 v52-4 IntroductionJune 2004 202-10036-01Extensive Protocol SupportThe WGR614 v5 router supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing Information Protocol (RIP). For further information about TCP/IP, refer to Appendix B, “Network, Routing, Firewall, and Basics.”• IP Address Sharing by NATThe WGR614 v5 router allows several networked computers to share an Internet account using only a single IP address, which may be statically or dynamically assigned by your Internet service provider (ISP). This technique, known as NAT, allows the use of an inexpensive single-user ISP account.• Automatic Configuration of Attached computers by DHCPThe WGR614 v5 router dynamically assigns network configuration information, including IP, gateway, and domain name server (DNS) addresses, to attached computers on the LAN using the Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies configuration of computers on your local network.• DNS ProxyWhen DHCP is enabled and no DNS addresses are specified, the router provides its own address as a DNS server to the attached computers. The router obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN.• PPP over Ethernet (PPPoE)PPPoE is a protocol for connecting remote hosts to the Internet over a DSL connection by simulating a dial-up connection. This feature eliminates the need to run a login program such as Entersys or WinPOET on your computer.Easy Installation and ManagementYou can install, configure, and operate the 54 Mbps Wireless Router WGR614 v5 within minutes after connecting it to the network. The following features simplify installation and management tasks:• Browser-based managementBrowser-based configuration allows you to easily configure your router from almost any type of personal computer, such as Windows, Macintosh, or Linux. A user-friendly Setup Wizard is provided and online help documentation is built into the browser-based Web Management Interface.• Smart WizardThe WGR614 v5 router Smart Wizard automatically senses the type of Internet connection, asking you only for the information required for your type of ISP account.

Wireless Configuration 4-1June 2004 202-10036-01Chapter 4Wireless ConfigurationThis chapter describes how to configure the wireless features of your WGR614 v5 router. In planning your wireless network, you should consider the level of security required. You should also select the physical placement of your firewall in order to maximize the network speed. For further information on wireless networking, refer to Appendix D, “Wireless Networking Basics.Observe Performance, Placement, and Range GuidelinesThe operating distance or range of your wireless connection can vary significantly based on the physical placement of the wireless firewall. The latency, data throughput performance, and notebook power consumption of wireless adapters also vary depending on your configuration choices.For best results, place your firewall:• Near the center of the area in which your computers will operate.• In an elevated location such as a high shelf where the wirelessly connected computers have line-of-sight access (even if through walls).• Away from sources of interference, such as computers, microwaves, and 2.4 GHz cordless phones.• Away from large metal surfaces.The time it takes to establish a wireless connection can vary depending on both your security settings and placement. WEP connections can take slightly longer to establish. Also, WEP encryption can consume more battery power on a notebook computer.Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the router. For complete range/performance specifications, please see Appendix A, “Technical Specifications.”
Reference Manual for the 54 Mbps Wireless Router WGR614 v54-2 Wireless ConfigurationJune 2004 202-10036-01Implement Appropriate Wireless Security Unlike wired network data, your wireless data transmissions can be received well beyond your walls by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The WGR614 v5 router provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs.Figure 4-1: WGR614 v5 wireless data security optionsThere are several ways you can enhance the security of your wireless network.•Restrict Access Based on MAC address. You can restrict access to only trusted computers so that unknown computers cannot wirelessly connect to the WGR614 v5. MAC address filtering adds an obstacle against unwanted access to your network, but the data broadcast over the wireless link is fully exposed. •Turn Off the Broadcast of the Wireless Network Name SSID. If you disable broadcast of the SSID, only devices that have the correct SSID can connect. This nullifies the wireless network ‘discovery’ feature of some products such as Windows XP, but the data is still fully exposed to a determined snoop using specialized test equipment like wireless sniffers.•WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared Key authentication and WEP data encryption will block all but the most determined eavesdropper. Note: Indoors, computers can connect over 802.11b/g wireless networks at ranges of up to 300 feet. Such distances can allow for others outside of your immediate area to access your network.:LUHOHVV'DWD6HFXULW\2SWLRQV5DQJHXSWRIRRWUDGLXV2SHQV\VWHPHDV\EXWQRVHFXULW\0$&DFFHVVOLVWQRGDWDVHFXULW\:(3VHFXULW\EXWVRPHSHUIRUPDQFHLPSDFW:3$36.YHU\VWURQJVHFXULW\WGR614 v5

Since the Trusted User will be identified by an IP address, you should configure that PC with a fixed IP address.Blocking Access to Internet ServicesThe WGR614 v5 router allows you to block the use of certain Internet services by PCs on your network. This is called services blocking or port filtering. The Block Services menu is shown below:Figure 5-2: Block Services menuServices are functions performed by server computers at the request of client computers. For example, Web servers serve Web pages, time servers serve time and date information, and game hosts serve data about other players’ moves. When a computer on your network sends a request for service to a server computer on the Internet, the requested service is identified by a service or port number. This number appears as the destination port number in the transmitted IP packets. For example, a packet that is sent with destination port number 80 is an HTTP (Web server) request.To enable service blocking, select either Per Schedule or Always, then click Apply. If you want to block by schedule, be sure that a time period is specified in the Schedule menu.

Advanced Configuration of the Router 7-1July 2004 202-10036-01Chapter 7Advanced Configuration of the Router This chapter describes how to configure the advanced features of your 54 Mbps Wireless Router WGR614 v5. These features can be found under the Advanced heading in the Main Menu of the browser interface..Configuring Port TriggeringPort Triggering is an advanced feature that can be used to easily enable gaming and other internet applications. Port Forwarding is typically used to enable similar functionality, but it is static and has some limitations. Note: If you use applications such as multi-player gaming, peer-to-peer connections, real time communications such as instant messaging, or remote assistance (a feature in Windows XP), you should also enable UPnP according to the instructions at “Using Universal Plug and Play (UPnP)“ on page 7-17.Port Triggering opens an incoming port temporarily and does not require the server on the internet to track your IP address if it is changed by DHCP, for example. Port Triggering monitors outbound traffic. When the router detects traffic on the specified outbound port, it remembers the IP address of the computer that sent the data and triggers the incoming port. Incoming traffic on the triggered port is then forwarded to the triggering computer. Using the Port Triggering page, you can make local computers or servers available to the Internet for different services (for example, FTP or HTTP), to play Internet games (like Quake III), or to use Internet applications (like CUseeMe). Port Forwarding is designed for FTP, Web Server or other server based services. Once port forwarding is set up, request from Internet will be forwarded to the proper server. On the contrary, Note: If you are unfamiliar with networking and routing, refer to Appendix B, “Network, Routing, Firewall, and Basics,” to become more familiar with the terms and procedures used in this chapter.

In addition to servers for specific applications, you can also specify a Default DMZ Server to which all other incoming protocols are forwarded. The DMZ Server is configured in the WAN Setup menu as discussed in “Configuring the WAN Setup Options“ on page 7-7.Before starting, you'll need to determine which type of service, application or game you'll provide and the IP address of the computer that will provide each service. Be sure the computer’s IP address never changes. To configure port forwarding to a local server:1. From the Service & Game box, select the service or game that you will host on your network.If the service does not appear in the list, refer to the following section, “Adding a Custom Service”.2. Enter the IP address of the local server in the corresponding Server IP Address box.3. Click the Add button.Note: To assure that the same computer always has the same IP address, use the reserved IP address feature of your WGR614 v5 router. See “Using Address Reservation“ on page 7-12 for instructions on how to use reserved IP addresses.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Advanced Configuration of the Router 7-5July 2004 202-10036-01Adding a Custom ServiceTo define a service, game or application that does not appear in the Services & Games list, you must determine what port numbers are used by the service. For this information, you may need to contact the manufacturer of the program that you wish to use. When you have the port number information, follow these steps:1. Click the Add Custom Service button.Figure 7-4: Ports - Custom Services Menu2. Type the service name in the Service Name box. 3. Type the beginning port number in the Starting Port box. • If the application uses only a single port; type the same port number in the Ending Port box. • If the application uses a range of ports; type the ending port number of the range in the Ending Port box. 4. Type the IP address of the computer in the Server IP Address box.5. Click Apply to save your changes.Editing or Deleting a Port Forwarding EntryTo edit or delete a Port Forwarding entry, follow these steps.1. In the table, select the button next to the service name.

Click Edit or Delete.Local Web and FTP Server ExampleIf a local computer with a private IP address of 192.168.0.33 acts as a Web and FTP server, configure the Ports menu to forward HTTP (port 80) and FTP (port 21) to local address 192.168.0.33 In order for a remote user to access this server from the Internet, the remote user must know the IP address that has been assigned by your ISP. If this address is 172.16.1.23, for example, an Internet user can access your Web server by directing the browser to http://172.16.1.23. The assigned IP address can be found in the Maintenance Status Menu, where it is shown as the WAN IP Address.Some considerations for this application are:• If your account’s IP address is assigned dynamically by your ISP, the IP address may change periodically as the DHCP lease expires.• If the IP address of the local computer is assigned by DHCP, it may change when the computer is rebooted. To avoid this, you can manually configure the computer to use a fixed address.• Local computers must access the local server using the computers’ local LAN address (192.168.0.33 in this example). Attempts by local computers to access the server using the external IP address (172.16.1.23 in this example) will fail.Multiple Computers for Half Life, KALI or Quake III ExampleTo set up an additional computer to play Half Life, KALI or Quake III: 1. Click the button of an unused port in the table. 2. Select the game again from the Services/Games list. 3. Change the beginning port number in the Start Port box. For these games, use the supplied number in the default listing and add +1 for each additional computer. For example, if you've already configured one computer to play Hexen II (using port 26900), the second computer's port number would be 26901, and the third computer would be 26902. 4. Type the same port number in the End Port box that you typed in the Start Port box. 5. Type the IP address of the additional computer in the Server IP Address box. 6. Click Apply.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Advanced Configuration of the Router 7-7July 2004 202-10036-01Some online games and videoconferencing applications are incompatible with NAT. The WGR614 v5 router is programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local computer can run the application properly if that computer’s IP address is entered as the default in the PORTS Menu. If one local computer acts as a game or videoconferencing host, enter its IP address as the default.Configuring the WAN Setup OptionsThe WAN Setup options let you configure a DMZ server, change the MTU size and enable the wireless router to respond to a Ping on the WAN port. These options are discussed below.Figure 7-5: WAN Setup menu.Connect Automatically, as Required Normally, this option should be checked to enable it. An Internet connection will be made automatically after each timeout, whenever Internet-bound traffic is detected. This provides connection on demand and is potentially cost-saving in places in Europe for example where Internet services charge by the minute. If disabled, you must connect manually, using the “Connection Status” button on the Router Status screen. This manual connection will stay up all the time without time outs.
Reference Manual for the 54 Mbps Wireless Router WGR614 v57-8 Advanced Configuration of the RouterJuly 2004 202-10036-01Disabling the SPI Firewall The SPI (Stateful Inspection) Firewall protects your LAN against Denial of Service attacks. This should only be disabled in special circumstances. Setting Up a Default DMZ ServerThe default DMZ server feature is helpful when using some online games and videoconferencing applications that are incompatible with NAT. The router is programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local computer can run the application properly if that computer’s IP address is entered as the default DMZ server.Incoming traffic from the Internet is normally discarded by the router unless the traffic is a response to one of your local computers or a service that you have configured in the Ports menu. Instead of discarding this traffic, you can have it forwarded to one computer on your network. This computer is called the Default DMZ Server.The WAN Setup menu, shown below lets you configure a Default DMZ Server.To assign a computer or server to be a Default DMZ server, follow these steps: 1. Click WAN Setup link on the Advanced section of the main menu. 2. Type the IP address for that server. To remove the default DMZ server, replace the IP address numbers with all zeros.3. Click Apply.Responding to Ping on Internet WAN Port If you want the router to respond to a 'ping' from the Internet, click the ‘Respond to Ping on Internet WAN Port’ check box. This should only be used as a diagnostic tool, since it allows your router to be discovered. Don't check this box unless you have a specific reason to do so.Note: DMZ servers pose a security risk. A computer designated as the default DMZ server loses much of the protection of the firewall, and is exposed to exploits from the Internet. If compromised, the DMZ server can be used to attack your network.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Advanced Configuration of the Router 7-9July 2004 202-10036-01Setting the MTU SizeThe normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes, 1492 Bytes for PPPoE connections, or 1436 for PPTP connections. For some ISPs you may need to reduce the MTU. But this is rarely required, and should not be done unless you are sure it is necessary for your ISP connection.Any packets sent through the router that are larger than the configured MTU size will be repackaged into smaller packets to meet the MTU requirement. To change the MTU size:1. Under MTU Size, enter a new size between 64 and 1500.2. Click Apply to save the new configuration.
Reference Manual for the 54 Mbps Wireless Router WGR614 v57-10 Advanced Configuration of the RouterJuly 2004 202-10036-01Using the LAN IP Setup OptionsThe second feature category under the Advanced heading is LAN IP Setup. This menu allows configuration of LAN IP services such as DHCP and RIP. From the Main Menu of the browser interface, under Advanced, click on LAN IP Setup to view the LAN IP Setup menu, shown below.Figure 7-6: LAN IP Setup MenuConfiguring LAN TCP/IP Setup ParametersThe router is shipped preconfigured to use private IP addresses on the LAN side, and to act.as a DHCP server. The router’s default LAN IP configuration is:• LAN IP addresses—192.168.0.1• Subnet mask—255.255.255.0
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Advanced Configuration of the Router 7-11July 2004 202-10036-01These addresses are part of the IETF-designated private address range for use in private networks, and should be suitable in most applications. If your network has a requirement to use a different IP addressing scheme, you can make those changes in this menu.The LAN IP parameters are:• IP AddressThis is the LAN IP address of the router.• IP Subnet MaskThis is the LAN Subnet Mask of the router. Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or router.• RIP DirectionRIP (Router Information Protocol) allows a router to exchange routing information with other routers. The RIP Direction selection controls how the router sends and receives RIP packets. Both is the default. — When set to Both or Out Only, the router will broadcast its routing table periodically. — When set to Both or In Only, it will incorporate the RIP information that it receives. — When set to None, it will not send any RIP packets and will ignore any RIP packets received. • RIP VersionThis controls the format and the broadcasting method of the RIP packets that the router sends. (It recognizes both formats when receiving.) By default, this is set for RIP-1. — RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you have an unusual network setup. — RIP-2 carries more information. RIP-2B uses subnet broadcasting.Note: If you change the LAN IP address of the router while connected through the browser, you will be disconnected. You must then open a new connection to the new IP address and log in again.
Reference Manual for the 54 Mbps Wireless Router WGR614 v57-12 Advanced Configuration of the RouterJuly 2004 202-10036-01Using the Router as a DHCP serverBy default, the router will function as a DHCP (Dynamic Host Configuration Protocol) server, allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to the router's LAN. The assigned default gateway address is the LAN address of the router. IP addresses will be assigned to the attached computers from a pool of addresses specified in this menu. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See “IPConfiguration by DHCP” on page B-10 for an explanation of DHCP and information about how to assign IP addresses for your network. If another device on your network will be the DHCP server, or if you will manually configure the network settings of all of your computers, clear the ‘Use router as DHCP server’ check box. Otherwise, leave it checked. Specify the pool of IP addresses to be assigned by setting the Starting IP Address and Ending IP Address. These addresses should be part of the same IP address subnet as the router’s LAN IP address. Using the default addressing scheme, you should define a range between 192.168.0.2 and 192.168.0.253, although you may wish to save part of the range for devices with fixed addresses.The router will deliver the following parameters to any LAN device that requests DHCP:• An IP Address from the range you have defined• Subnet Mask• Gateway IP Address (the router’s LAN IP address)• Primary DNS Server (if you entered a Primary DNS address in the Basic Settings menu; otherwise, the router’s LAN IP address)• Secondary DNS Server (if you entered a Secondary DNS address in the Basic Settings menuUsing Address ReservationWhen you specify a reserved IP address for a computer on the LAN, that computer will always receive the same IP address each time it access the router’s DHCP server. Reserved IP addresses should be assigned to servers that require permanent IP settings. To reserve an IP address: 1. Click the Add button.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Advanced Configuration of the Router 7-13July 2004 202-10036-012. In the IP Address box, type the IP address to assign to the computer or server.(choose an IP address from the router’s LAN subnet, such as 192.168.0.X) 3. Type the MAC Address of the computer or server. (Tip: If the computer is already present on your network, you can copy its MAC address from the Attached Devices menu and paste it here.) 4. Click Apply to enter the reserved address into the table. Note: The reserved address will not be assigned until the next time the computer contacts the router's DHCP server. Reboot the computer or access its IP configuration and force a DHCP release and renew. To edit or delete a reserved address entry: 1. Click the button next to the reserved address you want to edit or delete. 2. Click Edit or Delete.Using a Dynamic DNS ServiceIf your network has a permanently assigned IP address, you can register a domain name and have that name linked with your IP address by public Domain Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you will not know in advance what your IP address will be, and the address can change frequently. In this case, you can use a commercial dynamic DNS service, who will allow you to register your domain to their IP address, and will forward traffic directed at your domain to your frequently-changing IP address.The router contains a client that can connect to many popular dynamic DNS services. You can select one of these services and obtain an account with them. Then, whenever your ISP-assigned IP address changes, your router will automatically contact your dynamic DNS service provider, log in to your account, and register your new IP address.From the Main Menu of the browser interface, under Advanced, click on Dynamic DNS. To configure Dynamic DNS:Note: If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the dynamic DNS service will not work because private addresses will not be routed on the Internet.
Reference Manual for the 54 Mbps Wireless Router WGR614 v57-14 Advanced Configuration of the RouterJuly 2004 202-10036-011. Register for an account with one of the dynamic DNS service providers whose names appear in the ‘Select Service Provider’ box. For example, for dyndns.org, go to www.dyndns.org.2. Select the Use a dynamic DNS service check box. 3. Select the name of your dynamic DNS Service Provider. 4. Type the Host Name (or domain name) that your dynamic DNS service provider gave you.5. Type the User Name for your dynamic DNS account. 6. Type the Password (or key) for your dynamic DNS account. 7. If your dynamic DNS provider allows the use of wildcards in resolving your URL, you may select the Use wildcards check box to activate this feature. For example, the wildcard feature will cause *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org8. Click Apply to save your configuration.Configuring Static RoutesStatic Routes provide additional routing information to your router. Under normal circumstances, the router has adequate routing information after it has been configured for Internet access, and you do not need to configure additional static routes. You must configure static routes only for unusual cases such as multiple routers or multiple IP subnets located on your network.From the Main Menu of the browser interface, under Advanced, click on Static Routes to view the Static Route menu, shown below.Figure 7-7. Static Route Summary Table
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Advanced Configuration of the Router 7-15July 2004 202-10036-01To add or edit a Static Route:1. Click the Add button to open the Add/Edit Menu, shown below.Figure 7-8. Static Route Entry and Edit Menu2. Type a route name for this static route in the Route Name box under the table.(This is for identification purposes only.) 3. Select Private if you want to limit access to the LAN only. The static route will not be reported in RIP. 4. Select Active to make this route effective. 5. Type the Destination IP Address of the final destination. 6. Type the IP Subnet Mask for this destination.If the destination is a single host, type 255.255.255.255. 7. Type the Gateway IP Address, which must be a router on the same LAN segment as the router. 8. Type a number between 1 and 15 as the Metric value. This represents the number of routers between your network and the destination. Usually, a setting of 2 or 3 works, but if this is a direct connection, set it to 1. 9. Click Apply to have the static route entered into the table. As an example of when a static route is needed, consider the following case:• Your primary Internet access is through a cable modem to an ISP.• You have an ISDN router on your home network for connecting to the company where you are employed. This router’s address on your LAN is 192.168.0.100.• Your company’s network is 134.177.0.0.
Reference Manual for the 54 Mbps Wireless Router WGR614 v57-16 Advanced Configuration of the RouterJuly 2004 202-10036-01When you first configured your router, two implicit static routes were created. A default route was created with your ISP as the gateway, and a second static route was created to your local network for all 192.168.0.x addresses. With this configuration, if you attempt to access a device on the 134.177.0.0 network, your router will forward your request to the ISP. The ISP forwards your request to the company where you are employed, and the request will likely be denied by the company’s firewall.In this case you must define a static route, telling your router that 134.177.0.0 should be accessed through the ISDN router at 192.168.0.100. The static route would look like Figure 7-8.In this example:• The Destination IP Address and IP Subnet Mask fields specify that this static route applies to all 134.177.x.x addresses. • The Gateway IP Address fields specifies that all traffic for these addresses should be forwarded to the ISDN router at 192.168.0.100. • A Metric value of 1 will work since the ISDN router is on the LAN. • Private is selected only as a precautionary security measure in case RIP is activated.Enabling Remote Management AccessUsing the Remote Management page, you can allow a user or users on the Internet to configure, upgrade and check the status of your WGR614 v5 router.To configure your router for Remote Management:1. Select the Turn Remote Management On check box.2. Specify what external addresses will be allowed to access the router’s remote management.Note: For enhanced security, restrict access to as few external IP addresses as practical.a. To allow access from any IP address on the Internet, select Everyone. Note: Be sure to change the router's default configuration password to a very secure password. The ideal password should contain no dictionary words from any language, and should be a mixture of letters (both upper and lower case), numbers, and symbols. Your password can be up to 30 characters.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Advanced Configuration of the Router 7-17July 2004 202-10036-01b. To allow access from a range of IP addresses on the Internet, select IP address range.Enter a beginning and ending IP address to define the allowed range. c. To allow access from a single IP address on the Internet, select Only this computer.Enter the IP address that will be allowed access. 3. Specify the Port Number that will be used for accessing the management interface.Web browser access normally uses the standard HTTP service port 80. For greater security, change the remote management Web interface to a custom port by entering that number in the box provided. Choose a number between 1024 and 65535, but do not use the number of any common service port. The default is 8080, which is a common alternate for HTTP.4. Click Apply to have your changes take effect.Note: When accessing your router from the Internet, you will type your router's WAN IP address into your browser's Address (in IE) or Location (in Netscape) box, followed by a colon (:) and the custom port number. For example, if your external address is 134.177.0.123 and you use port number 8080, you must enter http://134.177.0.123:8080 in your browser.Using Universal Plug and Play (UPnP)Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network.Figure 7-9. UPnP Menu
Reference Manual for the 54 Mbps Wireless Router WGR614 v57-18 Advanced Configuration of the RouterJuly 2004 202-10036-01From the Main Menu of the browser interface, under Advanced, click on UPnP. Set up UPnP according to the guidelines below. Turn UPnP On: UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP is disabled. If disabled, the router will not allow any device to automatically control the resources, such as port forwarding (mapping), of the router. Note: If you use applications such as multi-player gaming, peer-to-peer connections, real time communications such as instant messaging, or remote assistance (a feature in Windows XP), you should enable UPnP.Advertisement Period: The Advertisement Period is how often the router will broadcast its UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations will ensure that control points have current device status at the expense of additional network traffic. Longer durations may compromise the freshness of the device status but can significantly reduce network traffic.Advertisement Time To Live: The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is allowed to propagate for each UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should be fine for most home networks. If you notice that some devices are not being updated or reached correctly, then it may be necessary to increase this value a little.UPnP Portmap Table: The UPnP Portmap Table displays the IP address of each UPnP device that is currently accessing the router and which ports (Internal and External) that device has opened. The UPnP Portmap Table also displays what type of port is opened and if that port is still active for each IP address.
Troubleshooting 8-1July 2004 202-10036-01Chapter 8TroubleshootingThis chapter gives information about troubleshooting your 54 Mbps Wireless Router WGR614 v5. After each problem description, instructions are provided to help you diagnose and solve the problem.Basic FunctioningAfter you turn on power to the router, the following sequence of events should occur:1. When power is first applied, verify that the Power light is on.2. After approximately 10 seconds, verify that:a. The power light is solid green.b. The LAN port lights are lit for any local ports that are connected.c. The Internet port light is lit.If a port’s light is lit, a link has been established to the connected device. If a LAN port is connected to a 100 Mbps device, verify that the port’s light is green. If the port is 10 Mbps, the light will be amber.If any of these conditions does not occur, refer to the appropriate following section.Power Light Not OnIf the Power and other lights are off when your router is turned on:• Make sure that the power cord is properly connected to your router and that the power supply adapter is properly connected to a functioning power outlet. • Check that you are using the 12 V DC 1A power adapter supplied by NETGEAR for this product.If the error persists, you have a hardware problem and should contact technical support.
Reference Manual for the 54 Mbps Wireless Router WGR614 v58-2 TroubleshootingJuly 2004 202-10036-01Lights Never Turn Off When the router is turned on, the lights turns on for about 10 seconds and then turn off. If all the lights stay on, there is a fault within the router.If all lights are still on one minute after power up:• Cycle the power to see if the router recovers.• Clear the router’s configuration to factory defaults. This will set the router’s IP address to 192.168.0.1. This procedure is explained in “Restoring the Default Configuration and Password” on page 8-7.If the error persists, you might have a hardware problem and should contact technical support.LAN or WAN Port Lights Not OnIf either the LAN lights or Internet light do not light when the Ethernet connection is made, check the following:• Make sure that the Ethernet cable connections are secure at the router and at the hub or workstation.• Make sure that power is turned on to the connected hub or workstation.• Be sure you are using the correct cable:— When connecting the router’s Internet port to a cable or DSL modem, use the cable that was supplied with the cable or DSL modem. This cable could be a standard straight-through Ethernet cable or an Ethernet crossover cable.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Troubleshooting 8-3July 2004 202-10036-01Troubleshooting the Web Configuration InterfaceIf you are unable to access the router’s Web Configuration interface from a computer on your local network, check the following:• Check the Ethernet connection between the computer and the router as described in the previous section.• Make sure your computer’s IP address is on the same subnet as the router. If you are using the recommended addressing scheme, your computer’s address should be in the range of 192.168.0.2 to 192.168.0.254. Refer to “Verifying TCP/IP Properties” on page C-8 or “Verifying TCP/IP Properties for Macintosh Computers” on page C-19 to find your computer’s IP address. Follow the instructions in Appendix C to configure your computer.Note: If your computer’s IP address is shown as 169.254.x.x: Recent versions of Windows and MacOS will generate and assign an IP address if the computer cannot reach a DHCP server. These auto-generated addresses are in the range of 169.254.x.x. If your IP address is in this range, check the connection from the computer to the router and reboot your computer.• If your router’s IP address has been changed and you don’t know the current IP address, clear the router’s configuration to factory defaults. This will set the router’s IP address to 192.168.0.1. This procedure is explained in “Restoring the Default Configuration and Password” on page 8-7.• Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure the Java applet is loaded.• Try quitting the browser and launching it again.• Make sure you are using the correct login information. The factory default login name is admin and the password is password. Make sure that CAPS LOCK is off when entering this information.If the router does not save changes you have made in the Web Configuration Interface, check the following:• When entering configuration settings, be sure to click the APPLY button before moving to another menu or tab, or your changes are lost. • Click the Refresh or Reload button in the Web browser. The changes may have occurred, but the Web browser may be caching the old configuration.
Reference Manual for the 54 Mbps Wireless Router WGR614 v58-4 TroubleshootingJuly 2004 202-10036-01Troubleshooting the ISP ConnectionIf your router is unable to access the Internet, you should first determine whether the router is able to obtain a WAN IP address from the ISP. Unless you have been assigned a static IP address, your router must request an IP address from the ISP. You can determine whether the request was successful using the Web Configuration Manager.To check the WAN IP address: 1. Launch your browser and select an external site such as www.netgear.com2. Access the Main Menu of the router’s configuration at http://www.routerlogin.net.3. Under the Maintenance heading, select Router Status4. Check that an IP address is shown for the WAN PortIf 0.0.0.0 is shown, your router has not obtained an IP address from your ISP.If your router is unable to obtain an IP address from the ISP, you may need to force your cable or DSL modem to recognize your new router by performing the following procedure:1. Turn off power to the cable or DSL modem. 2. Turn off power to your router. 3. Wait five minutes and reapply power to the cable or DSL modem. 4. When the modem’s lights indicate that it has reacquired sync with the ISP, reapply power to your router.5. Then restart your computer.If your router is still unable to obtain an IP address from the ISP, the problem may be one of the following:• Your ISP may require a login program.Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.• If your ISP requires a login, you may have incorrectly set the login name and password.• Your ISP may check for your computer's host name.Assign the computer Host Name of your ISP account as the Account Name in the Basic Settings menu.• Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for your computer’s MAC address. In this case:
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Troubleshooting 8-5July 2004 202-10036-01Inform your ISP that you have bought a new network device, and ask them to use the router’s MAC address.ORConfigure your router to spoof your computer’s MAC address. This can be done in the Basic Settings menu. Refer to “How to Bypass the Configuration Assistant” on page 3-12.If your router can obtain an IP address, but your computer is unable to load any Web pages from the Internet:• Your computer may not recognize any DNS server addresses. A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS servers for your use. If you entered a DNS address during the router’s configuration, reboot your computer and verify the DNS address as described in “Install or Verify Windows Networking Components” on page C-9. Alternatively, you may configure your computer manually with DNS addresses, as explained in your operating system documentation.• Your computer may not have the router configured as its TCP/IP gateway.If your computer obtains its information from the router by DHCP, reboot the computer and verify the gateway address as described in “Install or Verify Windows Networking Components” on page C-9.Troubleshooting a TCP/IP Network Using a Ping UtilityMost TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP network is made very easy by using the ping utility in your computer or workstation.Testing the LAN Path to Your RouterYou can ping the router from your computer to verify that the LAN path to your router is set up correctly.To ping the router from a running Windows 95 or later:1. From the Windows toolbar, click on the Start button and select Run.2. In the field provided, type Ping followed by the IP address of the router, as in this example:ping 192.168.0.1

Click on OK.You should see a message like this one:Pinging <IP address> with 32 bytes of dataIf the path is working, you see this message:Reply from < IP address >: bytes=32 time=NN ms TTL=xxxIf the path is not working, you see this message:Request timed outIf the path is not functioning correctly, you could have one of the following problems:• Wrong physical connections— Make sure the LAN port LED is on. If the LED is off, follow the instructions in “LAN or WAN Port Lights Not On” on page 8-2.— Check that the corresponding Link LEDs are on for your network interface card and for the hub ports (if any) that are connected to your workstation and router.• Wrong network configuration— Verify that the Ethernet card driver software and TCP/IP software are both installed and configured on your computer or workstation.— Verify that the IP address for your router and your workstation are correct and that the addresses are on the same subnet.Testing the Path from Your Computer to a Remote DeviceAfter verifying that the LAN path works correctly, test the path from your computer to a remote device. From the Windows run menu, type:PING -n 10 <IP address>where <IP address> is the IP address of a remote device such as your ISP’s DNS server.If the path is functioning correctly, replies as in the previous section are displayed. If you do not receive replies:— Check that your computer has the IP address of your router listed as the default gateway. If the IP configuration of your computer is assigned by DHCP, this information will not be visible in your computer’s Network Control Panel. Verify that the IP address of the router is listed as the default gateway as described in “Install or Verify Windows Networking Components” on page C-9.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Troubleshooting 8-7July 2004 202-10036-01— Check to see that the network address of your computer (the portion of the IP address specified by the netmask) is different from the network address of the remote device.— Check that your cable or DSL modem is connected and functioning.— If your ISP assigned a host name to your computer, enter that host name as the Account Name in the Basic Settings menu.— Your ISP could be rejecting the Ethernet MAC addresses of all but one of your computers. Many broadband ISPs restrict access by only allowing traffic from the MAC address of your broadband modem, but some ISPs additionally restrict access to the MAC address of a single computer connected to that modem. If this is the case, you must configure your router to “clone” or “spoof” the MAC address from the authorized computer. Refer to “How to Bypass the Configuration Assistant” on page 3-12.Restoring the Default Configuration and PasswordThis section explains how to restore the factory default configuration settings, changing the router’s administration password to password and the IP address to 192.168.0.1. You can erase the current configuration and restore factory defaults in two ways:• Use the Erase function of the router (see “Erasing the Configuration” on page 6-7).• Use the Default Reset button on the rear panel of the router. Use this method for cases when the administration password or IP address is not known.To restore the factory default configuration settings without knowing the administration password or IP address, you must use the Default Reset button on the rear panel of the router.1. Press and hold the Default Reset button until the power light blinks on (about 10 seconds).2. Release the Default Reset button and wait for the router to reboot.If the wireless router fails to restart or the power light continues to blink or turns solid amber, the unit may be defective. If the error persists, you might have a hardware problem and should contact technical support.

Network, Routing, Firewall, and Basics B-1July 2004 202-10036-01Appendix BNetwork, Routing, Firewall, and BasicsThis chapter provides an overview of IP networks, routing, and networking.Related PublicationsAs you read this document, you may be directed to various RFC documents for further information. An RFC is a Request For Comment (RFC) published by the Internet Engineering Task Force (IETF), an open organization that defines the architecture and operation of the Internet. The RFC documents outline and define the standard protocols and procedures for the Internet. The documents are listed on the World Wide Web at www.ietf.org and are mirrored and indexed at many other sites worldwide.Basic Router ConceptsLarge amounts of bandwidth can be provided easily and relatively inexpensively in a local area network (LAN). However, providing high bandwidth between a local network and the Internet can be very expensive. Because of this expense, Internet access is usually provided by a slower-speed wide-area network (WAN) link such as a cable or DSL modem. In order to make the best use of the slower WAN link, a mechanism must be in place for selecting and transmitting only the data traffic meant for the Internet. The function of selecting and forwarding this data is performed by a router.What is a Router?A router is a device that forwards traffic between networks based on network layer information in the data and on routing tables maintained by the router. In these routing tables, a router builds up a logical picture of the overall network by gathering and exchanging information with other routers in the network. Using this information, the router chooses the best path for forwarding network traffic.Routers vary in performance and scale, number of routing protocols supported, and types of physical WAN connection they support. The 54 Mbps Wireless Router WGR614 v5 is a small office router that routes the IP protocol over a single-user broadband connection.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5B-2 Network, Routing, Firewall, and BasicsJuly 2004 202-10036-01Routing Information ProtocolOne of the protocols used by a router to build and maintain a picture of the network is the Routing Information Protocol (RIP). Using RIP, routers periodically update one another and check for changes to add to the routing table.The WGR614 v5 router supports both the older RIP-1 and the newer RIP-2 protocols. Among other improvements, RIP-2 supports subnet and multicast protocols. RIP is not required for most home applications. IP Addresses and the InternetBecause TCP/IP networks are interconnected across the world, every machine on the Internet must have a unique address to make sure that transmitted data reaches the correct destination. Blocks of addresses are assigned to organizations by the Internet Assigned Numbers Authority (IANA). Individual users and small organizations may obtain their addresses either from the IANA or from an Internet service provider (ISP). You can contact IANA at www.iana.org.The Internet Protocol (IP) uses a 32-bit address structure. The address is usually written in dot notation (also called dotted-decimal notation), in which each group of eight bits is written in decimal form, separated by decimal points.For example, the following binary address: 11000011 00100010 00001100 00000111 is normally written as: 195.34.12.7The latter version is easier to remember and easier to enter into your computer.In addition, the 32 bits of the address are subdivided into two parts. The first part of the address identifies the network, and the second part identifies the host node or station on the network. The dividing point may vary depending on the address range and the application.There are five standard classes of IP addresses. These address classes have different ways of determining the network and host sections of the address, allowing for different numbers of hosts on a network. Each address type begins with a unique bit pattern, which is used by the TCP/IP software to identify the address class. After the address class has been determined, the software can correctly identify the host section of the address. The follow figure shows the three main address classes, including network and host sections of the address for each address type.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Network, Routing, Firewall, and Basics B-3July 2004 202-10036-01Figure B-1: Three Main Address ClassesThe five address classes are:• Class AClass A addresses can have up to 16,777,214 hosts on a single network. They use an eight-bit network number and a 24-bit node number. Class A addresses are in this range: 1.x.x.x to 126.x.x.x. • Class BClass B addresses can have up to 65,354 hosts on a network. A Class B address uses a 16-bit network number and a 16-bit node number. Class B addresses are in this range: 128.1.x.x to 191.254.x.x. • Class CClass C addresses can have 254 hosts on a network. Class C addresses use 24 bits for the network address and eight bits for the node. They are in this range:192.0.1.x to 223.255.254.x. • Class DClass D addresses are used for multicasts (messages sent to many hosts). Class D addresses are in this range:224.0.0.0 to 239.255.255.255. • Class EClass E addresses are for experimental use. 7261Class ANetwork NodeClass BClass CNetwork NodeNetwork Node
Reference Manual for the 54 Mbps Wireless Router WGR614 v5B-4 Network, Routing, Firewall, and BasicsJuly 2004 202-10036-01This addressing structure allows IP addresses to uniquely identify each physical network and each node on each physical network.For each unique value of the network portion of the address, the base address of the range (host address of all zeros) is known as the network address and is not usually assigned to a host. Also, the top address of the range (host address of all ones) is not assigned, but is used as the broadcast address for simultaneously sending a packet to all hosts with the same network address.NetmaskIn each of the address classes previously described, the size of the two parts (network address and host address) is implied by the class. This partitioning scheme can also be expressed by a netmask associated with the IP address. A netmask is a 32-bit quantity that, when logically combined (using an AND operator) with an IP address, yields the network address. For instance, the netmasks for Class A, B, and C addresses are 255.0.0.0, 255.255.0.0, and 255.255.255.0, respectively.For example, the address 192.168.170.237 is a Class C IP address whose network portion is the upper 24 bits. When combined (using an AND operator) with the Class C netmask, as shown here, only the network portion of the address remains:11000000 10101000 10101010 11101101 (192.168.170.237)combined with:11111111 11111111 11111111 00000000 (255.255.255.0)Equals:11000000 10101000 10101010 00000000 (192.168.170.0)As a shorter alternative to dotted-decimal notation, the netmask may also be expressed in terms of the number of ones from the left. This number is appended to the IP address, following a backward slash (/), as “/n.” In the example, the address could be written as 192.168.170.237/24, indicating that the netmask is 24 ones followed by 8 zeros. Subnet AddressingBy looking at the addressing structures, you can see that even with a Class C address, there are a large number of hosts per network. Such a structure is an inefficient use of addresses if each end of a routed link requires a different network number. It is unlikely that the smaller office LANs would have that many devices. You can resolve this problem by using a technique known as subnet addressing.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Network, Routing, Firewall, and Basics B-5July 2004 202-10036-01Subnet addressing allows us to split one IP network address into smaller multiple physical networks known as subnetworks. Some of the node numbers are used as a subnet number instead. A Class B address gives us 16 bits of node numbers translating to 64,000 nodes. Most organizations do not use 64,000 nodes, so there are free bits that can be reassigned. Subnet addressing makes use of those bits that are free, as shown below.Figure B-2: Example of Subnetting a Class B AddressA Class B address can be effectively translated into multiple Class C addresses. For example, the IP address of 172.16.0.0 is assigned, but node addresses are limited to 255 maximum, allowing eight extra bits to use as a subnet address. The IP address of 172.16.97.235 would be interpreted as IP network address 172.16, subnet number 97, and node number 235. In addition to extending the number of addresses available, subnet addressing provides other benefits. Subnet addressing allows a network manager to construct an address scheme for the network by using different subnets for other geographical locations in the network or for other departments in the organization.Although the preceding example uses the entire third octet for a subnet address, note that you are not restricted to octet boundaries in subnetting. To create more network numbers, you need only shift some bits from the host address to the network address. For instance, to partition a Class C network number (192.68.135.0) into two, you shift one bit from the host address to the network address. The new netmask (or subnet mask) is 255.255.255.128. The first subnet has network number 192.68.135.0 with hosts 192.68.135.1 to 129.68.135.126, and the second subnet has network number 192.68.135.128 with hosts 192.68.135.129 to 192.68.135.254.Note: The number 192.68.135.127 is not assigned because it is the broadcast address of the first subnet. The number 192.68.135.128 is not assigned because it is the network address of the second subnet.7262Class BNetwork Subnet Node
Reference Manual for the 54 Mbps Wireless Router WGR614 v5B-6 Network, Routing, Firewall, and BasicsJuly 2004 202-10036-01The following table lists the additional subnet mask bits in dotted-decimal notation. To use the table, write down the original class netmask and replace the 0 value octets with the dotted-decimal value of the additional subnet bits. For example, to partition your Class C network with subnet mask 255.255.255.0 into 16 subnets (4 bits), the new subnet mask becomes 255.255.255.240.The following table displays several common netmask values in both the dotted-decimal and the masklength formats.Configure all hosts on a LAN segment to use the same netmask for the following reasons:Table 8-1.

In order for this scheme to work, all devices on the segment must agree on which bits comprise the host address. • So that a local router or bridge recognizes which addresses are local and which are remotePrivate IP AddressesIf your local network is isolated from the Internet (for example, when using NAT), you can assign any IP addresses to the hosts without problems. However, the IANA has reserved the following three blocks of IP addresses specifically for private networks:10.0.0.0 - 10.255.255.255172.16.0.0 - 172.31.255.255192.168.0.0 - 192.168.255.255Choose your private network number from this range. The DHCP server of the WGR614 v5 router is preconfigured to automatically assign private addresses.Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines explained here. For more information about address assignment, refer to RFC 1597, Address Allocation for Private Internets, and RFC 1466, Guidelines for Management of IP Address Space. The Internet Engineering Task Force (IETF) publishes RFCs on its Web site at www.ietf.org.Single IP Address Operation Using NATIn the past, if multiple computers on a LAN needed to access the Internet simultaneously, you had to obtain a range of IP addresses from the ISP. This type of Internet account is more costly than a single-address account typically used by a single user with a modem, rather than a router. The WGR614 v5 router employs an address-sharing method called Network Address Translation (NAT). This method allows several networked computers to share an Internet account using only a single IP address, which may be statically or dynamically assigned by your ISP.The router accomplishes this address sharing by translating the internal LAN IP addresses to a single address that is globally unique on the Internet. The internal LAN IP addresses can be either private addresses or registered addresses. For more information about IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).
Reference Manual for the 54 Mbps Wireless Router WGR614 v5B-8 Network, Routing, Firewall, and BasicsJuly 2004 202-10036-01The following figure illustrates a single IP address operation.Figure B-3: Single IP Address Operation Using NATThis scheme offers the additional benefit of firewall-like protection because the internal LAN addresses are not available to the Internet through the translated connection. All incoming inquiries are filtered out by the router. This filtering can prevent intruders from probing your system. However, using port forwarding, you can allow one computer (for example, a Web server) on your local network to be accessible to outside users.MAC Addresses and Address Resolution ProtocolAn IP address alone cannot be used to deliver data from one LAN device to another. To send data between LAN devices, you must convert the IP address of the destination device to its media access control (MAC) address. Each device on an Ethernet network has a unique MAC address, which is a 48-bit number assigned to each device by the manufacturer. The technique that associates the IP address with a MAC address is known as address resolution. Internet Protocol uses the Address Resolution Protocol (ARP) to resolve MAC addresses.7786EA192.168.0.2192.168.0.3192.168.0.4192.168.0.5192.168.0.1 172.21.15.105Private IP addressesassigned by userInternetIP addressesassigned by ISP
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Network, Routing, Firewall, and Basics B-9July 2004 202-10036-01If a device sends data to another station on the network and the destination MAC address is not yet recorded, ARP is used. An ARP request is broadcast onto the network. All stations on the network receive and read the request. The destination IP address for the chosen station is included as part of the message so that only the station with this IP address responds to the ARP request. All other stations discard the request. Related DocumentsThe station with the correct IP address responds with its own MAC address directly to the sending device. The receiving station provides the transmitting station with the required destination MAC address. The IP address data and MAC address data for each station are held in an ARP table. The next time data is sent, the address can be obtained from the address information in the table.For more information about address assignment, refer to the IETF documents RFC 1597, Address Allocation for Private Internets, and RFC 1466, Guidelines for Management of IP Address Space.For more information about IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).Domain Name ServerMany of the resources on the Internet can be addressed by simple descriptive names such as www.NETGEAR.com. This addressing is very helpful at the application level, but the descriptive name must be translated to an IP address in order for a user to actually contact the resource. Just as a telephone directory maps names to phone numbers, or as an ARP table maps IP addresses to MAC addresses, a domain name system (DNS) server maps descriptive names of network resources to IP addresses.When a computer accesses a resource by its descriptive name, it first contacts a DNS server to obtain the IP address of the resource. The computer sends the desired message using the IP address. Many large organizations, such as ISPs, maintain their own DNS servers and allow their customers to use the servers to look up addresses.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5B-10 Network, Routing, Firewall, and BasicsJuly 2004 202-10036-01IP Configuration by DHCPWhen an IP-based local area network is installed, each computer must be configured with an IP address. If the computers need to access the Internet, they should also be configured with a gateway address and one or more DNS server addresses. As an alternative to manual configuration, there is a method by which each computer on the network can automatically obtain this configuration information. A device on the network may act as a Dynamic Host Configuration Protocol (DHCP) server. The DHCP server stores a list or pool of IP addresses, along with other information (such as gateway and DNS addresses) that it may assign to the other devices on the network. The WGR614 v5 router has the capacity to act as a DHCP server.The WGR614 v5 router also functions as a DHCP client when connecting to the ISP. The firewall can automatically obtain an IP address, subnet mask, DNS server addresses, and a gateway address if the ISP provides this information by DHCP.Internet Security and FirewallsWhen your LAN connects to the Internet through a router, an opportunity is created for outsiders to access or disrupt your network. A NAT router provides some protection because by the very nature of the process, the network behind the router is shielded from access by outsiders on the Internet. However, there are methods by which a determined hacker can possibly obtain information about your network or at the least can disrupt your Internet access. A greater degree of protection is provided by a firewall router.What is a Firewall?A firewall is a device that protects one network from another, while allowing communication between the two. A firewall incorporates the functions of the NAT router, while adding features for dealing with a hacker intrusion or attack. Several known types of intrusion or attack can be recognized when they occur. When an incident is detected, the firewall can log details of the attempt, and can optionally send E-mail to an administrator notifying them of the incident. Using information from the log, the administrator can take action with the ISP of the hacker. In some types of intrusions, the firewall can fend off the hacker by discarding all further packets from the hacker’s IP address for a period of time.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Network, Routing, Firewall, and Basics B-11July 2004 202-10036-01Stateful Packet InspectionUnlike simple Internet sharing routers, a firewall uses a process called stateful packet inspection to ensure secure firewall filtering to protect your network from attacks and intrusions. Since user-level applications such as FTP and Web browsers can create complex patterns of network traffic, it is necessary for the firewall to analyze groups of network connection states. Using Stateful Packet Inspection, an incoming packet is intercepted at the network layer and then analyzed for state-related information associated with all network connections. A central cache within the firewall keeps track of the state information associated with all network connections. All traffic passing through the firewall is analyzed against the state of these connections in order to determine whether or not it will be allowed to pass through or rejected.Denial of Service AttackA hacker may be able to prevent your network from operating or communicating by launching a Denial of Service (DoS) attack. The method used for such an attack can be as simple as merely flooding your site with more requests than it can handle. A more sophisticated attack may attempt to exploit some weakness in the operating system used by your router or gateway. Some operating systems can be disrupted by simply sending a packet with incorrect length information.Ethernet CablingAlthough Ethernet networks originally used thick or thin coaxial cable, most installations currently use unshielded twisted pair (UTP) cabling. The UTP cable contains eight conductors, arranged in four twisted pairs, and terminated with an RJ45 type connector. A normal straight-through UTP Ethernet cable follows the EIA568B standard wiring as described below in Table B-1.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5B-12 Network, Routing, Firewall, and BasicsJuly 2004 202-10036-01Category 5 Cable QualityCategory 5 distributed cable that meets ANSI/EIA/TIA-568-A building wiring standards can be a maximum of 328 feet (ft.) or 100 meters (m) in length, divided as follows:20 ft. (6 m) between the hub and the patch panel (if used)295 ft. (90 m) from the wiring closet to the wall outlet10 ft. (3 m) from the wall outlet to the desktop deviceThe patch panel and other connecting hardware must meet the requirements for 100 Mbps operation (Category 5). Only 0.5 inch (1.5 cm) of untwist in the wire pair is allowed at any termination point.A twisted pair Ethernet network operating at 10 Mbits/second (10BASE-T) will often tolerate low quality cables, but at 100 Mbits/second (10BASE-Tx) the cable must be rated as Category 5, or Cat 5, by the Electronic Industry Association (EIA). This rating will be printed on the cable jacket. A Category 5 cable will meet specified requirements regarding loss and crosstalk. In addition, there are restrictions on maximum cable length for both 10 and 100 Mbits/second networks.Table B-1.

The crossover function is usually implemented internally as part of the circuitry in the device. Computers and workstation adapter cards are usually media-dependent interface ports, called MDI or uplink ports. Most repeaters and switch ports are configured as media-dependent interfaces with built-in crossover ports, called MDI-X or normal ports. Auto Uplink technology automatically senses which connection, MDI or MDI-X, is needed and makes the right connection.Figure B-4 illustrates straight-through twisted pair cable.Figure B-4: Straight-Through Twisted-Pair CableFigure B-5 illustrates crossover twisted pair cable.Figure B-5: Crossover Twisted-Pair Cable

However, using telephone cable results in excessive collisions, causing the attached port to be partitioned or disconnected from the network.Uplink Switches, Crossover Cables, and MDI/MDIX SwitchingIn the wiring table above, the concept of transmit and receive are from the perspective of the computer, which is wired as Media Dependant Interface (MDI). In this wiring, the computer transmits on pins 1 and 2. At the hub, the perspective is reversed, and the hub receives on pins 1 and 2. This wiring is referred to as Media Dependant Interface - Crossover (MDI-X). When connecting a computer to a computer, or a hub port to another hub port, the transmit pair must be exchanged with the receive pair. This exchange is done by one of two mechanisms. Most hubs provide an Uplink switch which will exchange the pairs on one port, allowing that port to be connected to another hub using a normal Ethernet cable. The second method is to use a crossover cable, which is a special cable in which the transmit and receive pairs are exchanged at one of the two cable connectors. Crossover cables are often unmarked as such, and must be identified by comparing the two connectors. Since the cable connectors are clear plastic, it is easy to place them side by side and view the order of the wire colors on each. On a straight-through cable, the color order will be the same on both connectors. On a crossover cable, the orange and green pairs will be exchanged from one connector to the other.

Each LOCAL Ethernet port will automatically sense whether the Ethernet cable plugged into the port should have a normal connection (e.g. connecting to a computer) or an uplink connection (e.g. connecting to a router, switch, or hub). That port will then configure itself to the correct configuration. This feature also eliminates the need to worry about crossover cables, as Auto UplinkTM will accommodate either type of cable to make the right connection.

Preparing Your Network C-1July 2004 202-10036-01Appendix CPreparing Your NetworkThis appendix describes how to prepare your network to connect to the Internet through the 54 Mbps Wireless Router WGR614 v5 and how to verify the readiness of broadband Internet service from an Internet service provider (ISP).What You Need To Use a Router with a Broadband ModemYou need to prepare these three things before you begin:Cabling and Computer HardwareTo use the WGR614 v5 router on your network, each computer must have an 802.11g or 802.11b wireless adapter or an installed Ethernet Network Interface Card (NIC) and an Ethernet cable. If the computer will connect to your network using an Ethernet NIC at 100 Mbps, you must use a Category 5 (Cat 5) cable such as the one provided with your router. For an explanation of Ethernet cabling, see “Ethernet Cabling“ on page B-11. The cable or DSL broadband modem must provide a standard 10 Mbps (10BASE-T) or 100 Mbps (100BASE-Tx) Ethernet interface. Computer Network Configuration RequirementsThe WGR614 v5 includes a built-in Web Configuration Manager. To access the configuration menus on the WGR614 v5, your must use a Java-enabled Web browser program which supports HTTP uploads such as Microsoft Internet Explorer or Netscape Navigator. Use Internet Explorer or Netscape Navigator 4.0 or above. Note: If an ISP technician configured your computer during the installation of a broadband modem, or if you configured it using instructions provided by your ISP, you may need to copy the current configuration information for use in the configuration of your firewall. Write down this information before reconfiguring your computers. Refer to “Obtaining ISP Configuration Information for Windows Computers” on page C-21 or “Obtaining ISP Configuration Information for Macintosh Computers” on page C-22 for further information.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5C-2 Preparing Your NetworkJuly 2004 202-10036-01For the initial setup of your router, you will need to connect a computer to the router. This computer has to be set to automatically get its TCP/IP configuration from the router via DHCP.Note: For help with DHCP configuration, please use the Windows TCP/IP Configuration Tutorials on the NETGEAR 54 Mbps Wireless Router WGR614 v5 Resource CD (230-10091-01),or in this appendix.Internet Configuration RequirementsDepending on how your Internet service set up your account, you may need one or more of these configuration parameters to connect your router to the Internet: • Host and Domain Names• ISP Login Name and Password• ISP Domain Name Server (DNS) Addresses• Fixed IP Address which is also known as Static IP AddressWhere Do I Get the Internet Configuration Parameters?There are several ways you can gather the required Internet connection information.• Your Internet service provides all the information needed to connect to the Internet. If you cannot locate this information, you can ask your Internet service to provide it or you can try one of the options below.• If you have a computer already connected using the Internet, you can gather the configuration information from that computer.— For Windows 95/98/ME, open the Network control panel, select the TCP/IP entry for the Ethernet adapter, and click Properties.

Fill in the configuration parameters from your Internet Service Provider (ISP).ISP Login Name: The login name and password are case sensitive and must be entered exactly as given by your ISP. Some ISPs use your full e-mail address as the login name. The Service Name is not required by all ISPs. If you connect using a login name and password, enter the following:Login Name: ______________________________Password: ____________________________Service Name: _____________________________Fixed or Static IP Address: If you have a static IP address, record the following information. For example, 169.254.141.148 could be a valid IP address.Fixed or Static Internet IP Address: ______ ______ ______ ______Gateway IP Address: ______ ______ ______ ______Subnet Mask: ______ ______ ______ ______ISP DNS Server Addresses: If you were given DNS server addresses, fill in the following:Primary DNS Server IP Address: ______ ______ ______ ______Secondary DNS Server IP Address: ______ ______ ______ ______Host and Domain Names: Some ISPs use a specific host or domain name like CCA7324-A orhome. If you haven’t been given host or domain names, you can use the following examples as a guide:• If your main e-mail account with your ISP is aaa@yyy.com, then use aaa as your host name. Your ISP might call this your account, user, host, computer, or system name. • If your ISP’s mail server is mail.xxx.yyy.com, then use xxx.yyy.com as the domain name.ISP Host Name: _________________________ ISP Domain Name: _______________________For Wireless Access: See the configuration worksheet at “Information to Gather Before Changing Basic Wireless Settings“ on page 4-6.Preparing Your Computers for TCP/IP NetworkingComputers access the Internet using a protocol called TCP/IP (Transmission Control Protocol/Internet Protocol). Each computer on your network must have TCP/IP installed and selected as its networking protocol. If a Network Interface Card (NIC) is already installed in your computer, then TCP/IP is probably already installed as well.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5C-4 Preparing Your NetworkJuly 2004 202-10036-01Most operating systems include the software components you need for networking with TCP/IP:•Windows® 95 or later includes the software components for establishing a TCP/IP network. • Windows 3.1 does not include a TCP/IP component. You need to purchase a third-party TCP/IP application package such as NetManage Chameleon.• Macintosh Operating System 7 or later includes the software components for establishing a TCP/IP network.• All versions of UNIX or Linux include TCP/IP components. Follow the instructions provided with your operating system or networking software to install TCP/IP on your computer.In your IP network, each computer and the firewall must be assigned a unique IP addresses. Each computer must also have certain other IP configuration information such as a subnet mask (netmask), a domain name server (DNS) address, and a default gateway address. In most cases, you should install TCP/IP so that the computer obtains its specific network configuration information automatically from a DHCP server during bootup. For a detailed explanation of the meaning and purpose of these configuration items, refer to “Appendix B, “Network, Routing, Firewall, and Basics.”The WGR614 v5 router is shipped preconfigured as a DHCP server. The firewall assigns the following TCP/IP configuration information automatically when the PCs are rebooted:• PC or workstation IP addresses—192.168.0.2 through 192.168.0.254• Subnet mask—255.255.255.0• Gateway address (the firewall)—192.168.0.1These addresses are part of the IETF-designated private address range for use in private networks.Configuring Windows 95, 98, and Me for TCP/IP NetworkingAs part of the PC preparation process, you need to manually install and configure TCP/IP on each networked PC.

Reference Manual for the 54 Mbps Wireless Router WGR614 v5C-20 Preparing Your NetworkJuly 2004 202-10036-01Verifying the Readiness of Your Internet AccountFor broadband access to the Internet, you need to contract with an Internet service provider (ISP) for a single-user Internet access account using a cable modem or DSL modem. This modem must be a separate physical box (not a card) and must provide an Ethernet port intended for connection to a Network Interface Card (NIC) in a computer. Your firewall does not support a USB-connected broadband modem.For a single-user Internet account, your ISP supplies TCP/IP configuration information for one computer. With a typical account, much of the configuration information is dynamically assigned when your PC is first booted up while connected to the ISP, and you will not need to know that dynamic information. In order to share the Internet connection among several computers, your firewall takes the place of the single PC, and you need to configure it with the TCP/IP information that the single PC would normally use. When the firewall’s Internet port is connected to the broadband modem, the firewall appears to be a single PC to the ISP. The firewall then allows the PCs on the local network to masquerade as the single PC to access the Internet through the broadband modem. The method used by the firewall to accomplish this is called Network Address Translation (NAT) or IP masquerading.Are Login Protocols Used?Some ISPs require a special login protocol, in which you must enter a login name and password in order to access the Internet. If you normally log in to your Internet account by running a program such as WinPOET or EnterNet, then your account uses PPP over Ethernet (PPPoE). When you configure your router, you will need to enter your login name and password in the router’s configuration menus. After your network and firewall are configured, the firewall will perform the login task when needed, and you will no longer need to run the login program from your PC. It is not necessary to uninstall the login program.What Is Your Configuration Information?More and more, ISPs are dynamically assigning configuration information. However, if your ISP does not dynamically assign configuration information but instead used fixed configurations, your ISP should have given you the following basic information for your account:
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Preparing Your Network C-21July 2004 202-10036-01• An IP address and subnet mask• A gateway IP address, which is the address of the ISP’s router• One or more domain name server (DNS) IP addresses• Host name and domain suffixFor example, your account’s full server names may look like this:mail.xxx.yyy.comIn this example, the domain suffix is xxx.yyy.com.If any of these items are dynamically supplied by the ISP, your firewall automatically acquires them.If an ISP technician configured your PC during the installation of the broadband modem, or if you configured it using instructions provided by your ISP, you need to copy the configuration information from your PC’s Network TCP/IP Properties window or Macintosh TCP/IP Control Panel before reconfiguring your PC for use with the firewall. These procedures are described next.Obtaining ISP Configuration Information for Windows ComputersAs mentioned above, you may need to collect configuration information from your PC so that you can use this information when you configure the WGR614 v5 router. Following this procedure is only necessary when your ISP does not dynamically supply the account information. To get the information you need to configure the firewall for Internet access:1. On the Windows taskbar, click the Start button, point to Settings, and then click Control Panel.2. Double-click the Network icon.The Network window opens, which displays a list of installed components.3. Select TCP/IP, and then click Properties.The TCP/IP Properties dialog box opens.4. Select the IP Address tab.If an IP address and subnet mask are shown, write down the information. If an address is present, your account uses a fixed (static) IP address. If no address is present, your account uses a dynamically-assigned IP address. Click “Obtain an IP address automatically”.5. Select the Gateway tab.

You may also be prompted to insert your Windows CD.Obtaining ISP Configuration Information for Macintosh ComputersAs mentioned above, you may need to collect configuration information from your Macintosh so that you can use this information when you configure the WGR614 v5 router. Following this procedure is only necessary when your ISP does not dynamically supply the account information. To get the information you need to configure the firewall for Internet access:1. From the Apple menu, select Control Panels, then TCP/IP.The TCP/IP Control Panel opens, which displays a list of configuration settings. If the “Configure” setting is “Using DHCP Server”, your account uses a dynamically-assigned IP address. In this case, close the Control Panel and skip the rest of this section.2. If an IP address and subnet mask are shown, write down the information. 3. If an IP address appears under Router address, write down the address. This is the ISP’s gateway address.4. If any Name Server addresses are shown, write down the addresses. These are your ISP’s DNS addresses.5. If any information appears in the Search domains information box, write it down.6. Change the “Configure” setting to “Using DHCP Server”.7. Close the TCP/IP Control Panel.

Wireless Networking Basics D-1June 2004 202-10036-01Appendix DWireless Networking BasicsWireless Networking OverviewThe WGR614 v5 router conforms to the Institute of Electrical and Electronics Engineers (IEEE) 802.11g standard for wireless LANs (WLANs). On an 802.11 wireless link, data is encoded using direct-sequence spread-spectrum (DSSS) technology and is transmitted in the unlicensed radio spectrum at 2.5GHz. The maximum data rate for the 802.11g wireless link is 54 Mbps, but it will automatically back down from 54 Mbps when the radio signal is weak or when interference is detected. The 802.11 standard is also called Wireless Ethernet or Wi-Fi by the Wireless Ethernet Compatibility Alliance (WECA, see http://www.wi-fi.net), an industry standard group promoting interoperability among 802.11 devices. The 802.11 standard offers two methods for configuring a wireless network - ad hoc and infrastructure.Infrastructure ModeWith a wireless access point, you can operate the wireless LAN in the infrastructure mode. This mode provides wireless connectivity to multiple wireless network devices within a fixed range or area of coverage, interacting with wireless nodes via an antenna. In the infrastructure mode, the wireless access point converts airwave data into wired Ethernet data, acting as a bridge between the wired LAN and wireless clients. Connecting multiple access points via a wired Ethernet backbone can further extend the wireless network coverage. As a mobile computing device moves out of the range of one access point, it moves into the range of another. As a result, wireless clients can freely roam from one access point domain to another and still maintain seamless network connection.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5D-2 Wireless Networking BasicsJune 2004 202-10036-01Ad Hoc Mode (Peer-to-Peer Workgroup)In an ad hoc network, computers are brought together as needed; thus, there is no structure or fixed points to the network - each node can generally communicate with any other node. There is no access point involved in this configuration. This mode enables you to quickly set up a small wireless workgroup and allows workgroup members to exchange data or share printers as supported by Microsoft networking in the various Windows operating systems. Some vendors also refer to ad hoc networking as peer-to-peer group networking.In this configuration, network packets are directly sent and received by the intended transmitting and receiving stations. As long as the stations are within range of one another, this is the easiest and least expensive way to set up a wireless network. Network Name: Extended Service Set Identification (ESSID)The Extended Service Set Identification (ESSID) is one of two types of Service Set Identification (SSID). In an ad hoc wireless network with no access points, the Basic Service Set Identification (BSSID) is used. In an infrastructure wireless network that includes an access point, the ESSID is used, but may still be referred to as SSID.An SSID is a thirty-two character (maximum) alphanumeric key identifying the name of the wireless local area network. Some vendors refer to the SSID as network name. For the wireless devices in a network to communicate with each other, all devices must be configured with the same SSID.Wireless ChannelsIEEE 802.11g/b wireless nodes communicate with each other using radio frequency signals in the ISM (Industrial, Scientific, and Medical) band between 2.4 GHz and 2.5 GHz. Neighboring channels are 5 MHz apart. However, due to spread spectrum effect of the signals, a node sending signals using a particular channel will utilize frequency spectrum 12.5 MHz above and below the center channel frequency. As a result, two separate wireless networks using neighboring channels (for example, channel 1 and channel 2) in the same general vicinity will interfere with each other. Applying two channels that allow the maximum channel separation will decrease the amount of channel cross-talk, and provide a noticeable performance increase over networks with minimal channel separation.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Wireless Networking Basics D-3June 2004 202-10036-01The radio frequency channels used are listed in Table D-1:Note: The available channels supported by the wireless products in various countries are different.The preferred channel separation between the channels in neighboring wireless networks is 25 MHz (5 channels). This means that you can apply up to three different channels within your wireless network. There are only 11 usable wireless channels in the United States. It is recommended that you start using channel 1 and grow to use channel 6, and 11 when necessary, as these three channels do not overlap.Table D-1. 802.11g Radio Frequency ChannelsChannel Center Frequency Frequency Spread1 2412 MHz 2399.5 MHz - 2424.5 MHz2 2417 MHz 2404.5 MHz - 2429.5 MHz3 2422 MHz 2409.5 MHz - 2434.5 MHz4 2427 MHz 2414.5 MHz - 2439.5 MHz5 2432 MHz 2419.5 MHz - 2444.5 MHz6 2437 MHz 2424.5 MHz - 2449.5 MHz7 2442 MHz 2429.5 MHz - 2454.5 MHz8 2447 MHz 2434.5 MHz - 2459.5 MHz9 2452 MHz 2439.5 MHz - 2464.5 MHz10 2457 MHz 2444.5 MHz - 2469.5 MHz11 2462 MHz 2449.5 MHz - 2474.5 MHz12 2467 MHz 2454.5 MHz - 2479.5 MHz13 2472 MHz 2459.5 MHz - 2484.5 MHz
Reference Manual for the 54 Mbps Wireless Router WGR614 v5D-4 Wireless Networking BasicsJune 2004 202-10036-01WEP Wireless SecurityThe absence of a physical connection between nodes makes the wireless links vulnerable to eavesdropping and information theft. To provide a certain level of security, the IEEE 802.11 standard has defined two types of authentication methods, Open System and Shared Key. With Open System authentication, a wireless computer can join any network and receive any messages that are not encrypted. With Shared Key authentication, only those computers that possess the correct authentication key can join the network. By default, IEEE 802.11 wireless devices operate in an Open System network. Recently, Wi-Fi, the Wireless Ethernet Compatibility Alliance (http://www.wi-fi.net) developed the Wi-Fi Protected Access (WPA), a new strongly enhanced Wi-Fi security. WPA will soon be incorporated into the IEEE 802.11 standard. WEP and WPA are discussed below.WEP AuthenticationThe 802.11 standard defines several services that govern how two 802.11 devices communicate. The following events must occur before an 802.11 Station can communicate with an Ethernet network through an access point such as the one built in to the WGR614 v5:1. Turn on the wireless station.2. The station listens for messages from any access points that are in range.3. The station finds a message from an access point that has a matching SSID.4. The station sends an authentication request to the access point.5. The access point authenticates the station.6. The station sends an association request to the access point.7. The access point associates with the station.8. The station can now communicate with the Ethernet network through the access point.An access point must authenticate a station before the station can associate with the access point or communicate with the network. The IEEE 802.11 standard defines two types of WEP authentication: Open System and Shared Key.• Open System Authentication allows any device to join the network, assuming that the device SSID matches the access point SSID. Alternatively, the device can use the “ANY” SSID option to associate with any available access point within range, regardless of its SSID.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Wireless Networking Basics D-5June 2004 202-10036-01• Shared Key Authentication requires that the station and the access point have the same WEP Key to authenticate. These two authentication procedures are described below.WEP Open System AuthenticationThis process is illustrated in below.Figure D-1: 802.11 open system authenticationThe following steps occur when two devices use Open System Authentication:1.

The station sends an authentication request to the access point.2. The access point sends challenge text to the station.3. The station uses its configured 64-bit or 128-bit default key to encrypt the challenge text, and sends the encrypted text to the access point.4. The access point decrypts the encrypted text using its configured WEP Key that corresponds to the station’s default key. The access point compares the decrypted text with the original challenge text. If the decrypted text matches the original challenge text, then the access point and the station share the same WEP Key and the access point authenticates the station. 5. The station connects to the network.If the decrypted text does not match the original challenge text (i.e., the access point and station do not share the same WEP Key), then the access point will refuse to authenticate the station and the station will be unable to communicate with either the 802.11 network or Ethernet network.INTERNET LOCALACT12345678LNKLNK/ACT100Cable/DSL ProSafeWirelessVPN SecurityFirewallMODEL FVM318PWR TESTWLANEnableAccess Point1) Authenticationrequest sent to AP2) AP sends challenge text3) Client encryptschallenge text andsends it back to AP4) AP decrypts, and if correct,authenticates client5) Client connects to networkShared KeyAuthentication StepsCable orDLS modemClientattemptingto connect
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Wireless Networking Basics D-7June 2004 202-10036-01Key Size and ConfigurationThe IEEE 802.11 standard supports two types of WEP encryption: 40-bit and 128-bit.The 64-bit WEP data encryption method, allows for a five-character (40-bit) input. Additionally, 24 factory-set bits are added to the forty-bit input to generate a 64-bit encryption key. (The 24 factory-set bits are not user-configurable). This encryption key will be used to encrypt/decrypt all data transmitted via the wireless interface. Some vendors refer to the 64-bit WEP data encryption as 40-bit WEP data encryption since the user-configurable portion of the encryption key is 40 bits wide.The 128-bit WEP data encryption method consists of 104 user-configurable bits. Similar to the forty-bit WEP data encryption method, the remaining 24 bits are factory set and not user configurable. Some vendors allow passphrases to be entered instead of the cryptic hexadecimal characters to ease encryption key entry.128-bit encryption is stronger than 40-bit encryption, but 128-bit encryption may not be available outside of the United States due to U.S. export regulations.When configured for 40-bit encryption, 802.11 products typically support up to four WEP Keys. Each 40-bit WEP Key is expressed as 5 sets of two hexadecimal digits (0-9 and A-F). For example, “12 34 56 78 90” is a 40-bit WEP Key.When configured for 128-bit encryption, 802.11g products typically support four WEP Keys but some manufacturers support only one 128-bit key. The 128-bit WEP Key is expressed as 13 sets of two hexadecimal digits (0-9 and A-F). For example, “12 34 56 78 90 AB CD EF 12 34 56 78 90” is a 128-bit WEP Key.Typically, 802.11 access points can store up to four 128-bit WEP Keys but some 802.11 client adapters can only store one. Therefore, make sure that your 802.11 access and client adapters configurations match.Whatever keys you enter for an AP, you must also enter the same keys for the client adapter in the same order. In other words, WEP key 1 on the AP must match WEP key 1 on the client adapter, WEP key 2 on the AP must match WEP key 2 on the client adapter, etc.Note: The AP and the client adapters can have different default WEP Keys as long as the keys are in the same order. In other words, the AP can use WEP key 2 as its default key to transmit while a client adapter can use WEP key 3 as its default key to transmit. The two devices will communicate as long as the AP’s WEP key 2 is the same as the client’s WEP key 2 and the AP’s WEP key 3 is the same as the client’s WEP key 3.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5D-8 Wireless Networking BasicsJune 2004 202-10036-01How to Use WEP ParametersWired Equivalent Privacy (WEP) data encryption is used when the wireless devices are configured to operate in Shared Key authentication mode. There are two shared key methods implemented in most commercially available products, 64-bit and 128-bit WEP data encryption.Before enabling WEP on an 802.11 network, you must first consider what type of encryption you require and the key size you want to use. Typically, there are three WEP Encryption options available for 802.11 products:1. Do Not Use WEP: The 802.11 network does not encrypt data. For authentication purposes, the network uses Open System Authentication.2. Use WEP for Encryption: A transmitting 802.11 device encrypts the data portion of every packet it sends using a configured WEP Key. The receiving 802.11g device decrypts the data using the same WEP Key. For authentication purposes, the 802.11g network uses Open System Authentication.3. Use WEP for Authentication and Encryption: A transmitting 802.11 device encrypts the data portion of every packet it sends using a configured WEP Key. The receiving 802.11 device decrypts the data using the same WEP Key. For authentication purposes, the 802.11 network uses Shared Key Authentication.Note: Some 802.11 access points also support Use WEP for Authentication Only (Shared Key Authentication without data encryption). However, the WGR614 v5 does not offer this option.WPA Wireless SecurityWi-Fi Protected Access (WPA) is a specification of standards-based, interoperable security enhancements that increase the level of data protection and access control for existing and future wireless LAN systems. The IEEE introduced the WEP as an optional security measure to secure 802.11g (Wi-Fi) WLANs, but inherent weaknesses in the standard soon became obvious. In response to this situation, the Wi-Fi Alliance announced a new security architecture in October 2002 that remedies the short comings of WEP. This standard, formerly known as Safe Secure Network (SSN), is designed to work with existing 802.11 products and offers forward compatibility with 802.11i, the new wireless security architecture being defined in the IEEE. WPA offers the following benefits:
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Wireless Networking Basics D-9June 2004 202-10036-01• Enhanced data privacy• Robust key management• Data origin authentication• Data integrity protection The Wi-Fi Alliance is now performing interoperability certification testing on Wi-Fi Protected Access products. Starting August of 2003, all new Wi-Fi certified products will have to support WPA. NETGEAR will implement WPA on client and access point products and make this available in the second half of 2003. Existing Wi-Fi certified products will have one year to add WPA support or they will loose their Wi-Fi certification. The 802.11i standard is currently in draft form, with ratification due at the end of 2003. While the new IEEE 802.11i standard is being ratified, wireless vendors have agreed on WPA as an interoperable interim standard. How Does WPA Compare to WEP?WEP is a data encryption method and is not intended as a user authentication mechanism. WPA user authentication is implemented using 802.1x and the Extensible Authentication Protocol (EAP). Support for 802.1x authentication is required in WPA. In the 802.11 standard, 802.1x authentication was optional. For details on EAP specifically, refer to IETF's RFC 2284. With 802.11 WEP, all access points and client wireless adapters on a particular wireless LAN must use the same encryption key. A major problem with the 802.11 standard is that the keys are cumbersome to change. If you don't update the WEP keys often, an unauthorized person with a sniffing tool can monitor your network for less than a day and decode the encrypted messages. Products based on the 802.11 standard alone offer system administrators no effective method to update the keys.For 802.11, WEP encryption is optional. For WPA, encryption using Temporal Key Integrity Protocol (TKIP) is required. TKIP replaces WEP with a new encryption algorithm that is stronger than the WEP algorithm, but that uses the calculation facilities present on existing wireless devices to perform encryption operations. TKIP provides important data encryption enhancements including a per-packet key mixing function, a message integrity check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism. Through these enhancements, TKIP addresses all of known WEP vulnerabilities.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5D-10 Wireless Networking BasicsJune 2004 202-10036-01How Does WPA Compare to IEEE 802.11i? WPA will be forward compatible with the IEEE 802.11i security specification currently under development. WPA is a subset of the current 802.11i draft and uses certain pieces of the 802.11i draft that are ready to bring to market today, such as 802.1x and TKIP. The main pieces of the 802.11i draft that are not included in WPA are secure IBSS (Ad-Hoc mode), secure fast handoff (for specialized 802.11 VoIP phones), as well as enhanced encryption protocols such as AES-CCMP. These features are either not yet ready for market or will require hardware upgrades to implement. What are the Key Features of WPA Security?The following security features are included in the WPA standard: • WPA Authentication• WPA Encryption Key Management– Temporal Key Integrity Protocol (TKIP)–Michael message integrity code (MIC)– AES Support• Support for a Mixture of WPA and WEP Wireless ClientsThese features are discussed below.WPA addresses most of the known WEP vulnerabilities and is primarily intended for wireless infrastructure networks as found in the enterprise. This infrastructure includes stations, access points, and authentication servers (typically RADIUS servers). The RADIUS server holds (or has access to) user credentials (e.g., user names and passwords) and authenticates wireless users before they gain access to the network.The strength WPA comes from an integrated sequence of operations that encompass 802.1X/EAP authentication and sophisticated key management and encryption techniques. Its major operations include:• Network security capability determination. This occurs at the 802.11 level and is communicated through WPA information elements in Beacon, Probe Response, and (Re) Association Requests. Information in these elements includes the authentication method (802.1X or Pre-shared key) and the preferred cipher suite (WEP, TKIP, or AES).
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Wireless Networking Basics D-11June 2004 202-10036-01The primary information conveyed in the Beacon frames is the authentication method and the cipher suite. Possible authentication methods include 802.1X and Pre-shared key. Pre-shared key is an authentication method that uses a statically configured pass phrase on both the stations and the access point. This obviates the need for an authentication server, which in many home and small office environments will not be available nor desirable. Possible cipher suites include: WEP, TKIP, and AES (Advanced Encryption Standard). We’ll talk more TKIP and AES when addressing data privacy below.• Authentication. EAP over 802.1X is used for authentication. Mutual authentication is gained by choosing an EAP type supporting this feature and is required by WPA. 802.1X port access control prevents full access to the network until authentication completes. 802.1X EAPOL-Key packets are used by WPA to distribute per-session keys to those stations successfully authenticated.The supplicant in the station uses the authentication and cipher suite information contained in the information elements to decide which authentication method and cipher suite to use. For example, if the access point is using the Pre-shared key method then the supplicant need not authenticate using full-blown 802.1X. Rather, the supplicant must simply prove to the access point that it is in possession of the pre-shared key. If the supplicant detects that the service set does not contain a WPA information element then it knows it must use pre-WPA 802.1X authentication and key management in order to access the network.• Key management. WPA features a robust key generation/management system that integrates the authentication and data privacy functions. Keys are generated after successful authentication and through a subsequent 4-way handshake between the station and Access Point (AP).• Data Privacy (Encryption). Temporal Key Integrity Protocol (TKIP) is used to wrap WEP in sophisticated cryptographic and security techniques to overcome most of its weaknesses.• Data integrity. TKIP includes a message integrity code (MIC) at the end of each plaintext message to ensure messages are not being spoofed.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5D-12 Wireless Networking BasicsJune 2004 202-10036-01WPA Authentication: Enterprise-level User Authentication via 802.1x/EAP and RADIUSFigure D-3: WPA OverviewIEEE 802.1x offers an effective framework for authenticating and controlling user traffic to a protected network, as well as providing a vehicle for dynamically varying data encryption keys via EAP from a RADIUS server, for example. This framework enables using a central authentication server, which employs mutual authentication so that a rogue wireless user does not join the network. It's important to note that 802.1x doesn't provide the actual authentication mechanisms. When using 802.1x, the EAP type, such as Transport Layer Security (EAP-TLS) or EAP Tunneled Transport Layer Security (EAP-TTLS) defines how the authentication takes place. Note: For environments with a Remote Authentication Dial-In User Service (RADIUS) infrastructure, WPA supports Extensible Authentication Protocol (EAP). For environments without a RADIUS infrastructure, WPA supports the use of a preshared key.Together, these technologies provide a framework for strong user authentication. Windows XP implements 802.1x natively, and several Netgear switch and wireless access point products support 802.1x.

Information elements include the required authentication method (802.1x or Pre-shared key) and the preferred cipher suite (WEP, TKIP, or AES). Probe Responses (AP to station) and Association Requests (station to AP) also contain WPA information elements.1. Initial 802.1x communications begin with an unauthenticated supplicant (i.e., client device) attempting to connect with an authenticator (i.e., 802.11 access point). The client sends an EAP-start message. This begins a series of message exchanges to authenticate the client. 2. The access point replies with an EAP-request identity message. 1234567Client with a WPA- enabled wireless adapter and supplicant (Win XP, Funk, Meetinghouse, etc.)For example, a WPA-enabled AP For example, a RADIUS server
Reference Manual for the 54 Mbps Wireless Router WGR614 v5D-14 Wireless Networking BasicsJune 2004 202-10036-013. The client sends an EAP-response packet containing the identity to the authentication server. The access point responds by enabling a port for passing only EAP packets from the client to an authentication server located on the wired side of the access point. The access point blocks all other traffic, such as HTTP, DHCP, and POP3 packets, until the access point can verify the client's identity using an authentication server (e.g., RADIUS). 4. The authentication server uses a specific authentication algorithm to verify the client's identity. This could be through the use of digital certificates or some other EAP authentication type. 5. The authentication server will either send an accept or reject message to the access point. 6. The access point sends an EAP-success packet (or reject packet) to the client. 7. If the authentication server accepts the client, then the access point will transition the client's port to an authorized state and forward additional traffic. The important part to know at this point is that the software supporting the specific EAP type resides on the authentication server and within the operating system or application “supplicant” software on the client devices. The access point acts as a “pass through” for 802.1x messages, which means that you can specify any EAP type without needing to upgrade an 802.1x-compliant access point. As a result, you can update the EAP authentication type to such devices as token cards (Smart Cards), Kerberos, one-time passwords, certificates, and public key authentication or as newer types become available and your requirements for security change. WPA Data Encryption Key ManagementWith 802.1x, the rekeying of unicast encryption keys is optional. Additionally, 802.11 and 802.1x provide no mechanism to change the global encryption key used for multicast and broadcast traffic. With WPA, rekeying of both unicast and global encryption keys is required. For the unicast encryption key, the Temporal Key Integrity Protocol (TKIP) changes the key for every frame, and the change is synchronized between the wireless client and the wireless access point (AP). For the global encryption key, WPA includes a facility (the Information Element) for the wireless AP to advertise the changed key to the connected wireless clients.If configured to implement dynamic key exchange, the 802.1x authentication server can return session keys to the access point along with the accept message. The access point uses the session keys to build, sign and encrypt an EAP key message that is sent to the client immediately after sending the success message. The client can then use contents of the key message to define applicable encryption keys. In typical 802.1x implementations, the client can automatically change encryption keys as often as necessary to minimize the possibility of eavesdroppers having enough time to crack the key in current use.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Wireless Networking Basics D-15June 2004 202-10036-01Temporal Key Integrity Protocol (TKIP)WPA uses TKIP to provide important data encryption enhancements including a per-packet key mixing function, a message integrity check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism. TKIP also provides for the following:• The verification of the security configuration after the encryption keys are determined. • The synchronized changing of the unicast encryption key for each frame. • The determination of a unique starting unicast encryption key for each preshared key authentication.MichaelWith 802.11 and WEP, data integrity is provided by a 32-bit integrity check value (ICV) that is appended to the 802.11 payload and encrypted with WEP. Although the ICV is encrypted, you can use cryptanalysis to change bits in the encrypted payload and update the encrypted ICV without being detected by the receiver.With WPA, a method known as Michael specifies a new algorithm that calculates an 8-byte message integrity code (MIC) using the calculation facilities available on existing wireless devices. The MIC is placed between the data portion of the IEEE 802.11 frame and the 4-byte ICV. The MIC field is encrypted together with the frame data and the ICV.Michael also provides replay protection. A new frame counter in the IEEE 802.11 frame is used to prevent replay attacks.AES SupportOne of the encryption methods supported by WPA beside TKIP is the advanced encryption standard (AES), although AES support will not be required initially for Wi-Fi certification. This is viewed as the optimal choice for security conscience organizations, but the problem with AES is that it requires a fundamental redesign of the NIC’s hardware in both the station and the access point. TKIP was a pragmatic compromise that allows organizations to deploy better security while AES capable equipment is being designed, manufactured, and incrementally deployed.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5D-16 Wireless Networking BasicsJune 2004 202-10036-01Is WPA Perfect?WPA is not without its vulnerabilities. Specifically, it is susceptible to denial of service (DoS) attacks. If the access point receives two data packets that fail the Message Integrity Code (MIC) check within 60 seconds of each other then the network is under an active attack, and as a result, the access point employs counter measures, which includes disassociating each station using the access point. This prevents an attacker from gleaning information about the encryption key and alerts administrators, but it also causes users to lose network connectivity for 60 seconds. More than anything else, this may just prove that no single security tactic is completely invulnerable. WPA is a definite step forward in WLAN security over WEP and has to be thought of as a single part of an end-to-end network security strategy.Product Support for WPAStarting in August, 2003, NETGEAR, Inc. wireless Wi-Fi certified products will support the WPA standard. NETGEAR, Inc. wireless products that had their Wi-Fi certification approved before August, 2003 will have one year to add WPA so as to maintain their Wi-Fi certification.WPA requires software changes to the following: • Wireless access points • Wireless network adapters • Wireless client programsSupporting a Mixture of WPA and WEP Wireless ClientsTo support the gradual transition of WEP-based wireless networks to WPA, a wireless AP can support both WEP and WPA clients at the same time. During the association, the wireless AP determines which clients use WEP and which clients use WPA. The disadvantage to supporting a mixture of WEP and WPA clients is that the global encryption key is not dynamic. This is because WEP-based clients cannot support it. All other benefits to the WPA clients, such as integrity, are maintained.However, a mixed mode supporting WPA and non-WPA clients would offer network security that is no better than that obtained with a non-WPA network, and thus this mode of operation is discouraged.Changes to Wireless Access PointsWireless access points must have their firmware updated to support the following:

Microsoft has worked with many wireless vendors to embed the WPA firmware update in the wireless adapter driver. So, to update you Windows wireless client, all you have to do is obtain the new WPA-compatible driver and install the driver. The firmware is automatically updated when the wireless network adapter driver is loaded in Windows.

AESAdvanced Encryption Standard, a symmetric 128-bit block data encryption technique. It is an iterated block cipher with a variable block length and a variable key length. The block length and the key length can be independently specified to 128, 192 or 256 bits.The U.S government adopted the algorithm as its encryption technique in October 2000, replacing the DES encryption it used. AES works at multiple network layers simultaneously.ARPAddress Resolution Protocol, a TCP/IP protocol used to convert an IP address into a physical address (called a DLC address), such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host on the network that has the IP address in the request then replies with its physical hardware address. There is also Reverse ARP (RARP) which can be used by a host to discover its IP address. In this case, the host broadcasts its physical address and a RARP server replies with the host's IP address.Auto UplinkAuto UplinkTM technology (also called MDI/MDIX) eliminates the need to worry about crossover vs. straight-through Ethernet cables. Auto UplinkTM will accommodate either type of cable to make the right connection.Cat 5Category 5 unshielded twisted pair (UTP) cabling. An Ethernet network operating at 10 Mbits/second (10BASE-T) will often tolerate low quality cables, but at 100 Mbits/second (10BASE-Tx) the cable must be rated as Category 5, or Cat 5 or Cat V, by the Electronic Industry Association (EIA). This rating will be printed on the cable jacket. Cat 5 cable contains eight conductors, arranged in four twisted pairs, and terminated with an RJ45 type connector. In addition, there are restrictions on maximum cable length for both 10 and 100 Mbits/second networks.Denial of Service attackDoS. A hacker attack designed to prevent your computer or network from operating or communicating.DHCPAn Ethernet protocol specifying how a centralized DHCP server can assign network configuration information to multiple DHCP clients. The assigned information includes IP addresses, DNS addresses, and gateway (router) addresses.DMZA Demilitarized Zone is used by a company that wants to host its own Internet services without sacrificing unauthorized access to its private network.
Reference Manual for the 54 Mbps Wireless Router WGR614 v5Glossary 3June 2004 202-10036-01The DMZ sits between the Internet and an internal network's line of defense, usually some combination of firewalls and bastion hosts. Typically, the DMZ contains devices accessible to Internet traffic, such as Web (HTTP) servers, FTP servers, SMTP (e-mail) servers and DNS servers. DNSShort for Domain Name System (or Service), an Internet service that translates domain names into IP addresses.Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned. Domain NameA descriptive name for an address or group of addresses on the Internet. Domain names are of the form of a registered entity name plus one of a number of predefined top level suffixes such as .com, .edu, .uk, etc. For example, in the address mail.NETGEAR.com, mail is a server name and NETGEAR.com is the domain.DoSA hacker attack designed to prevent your computer or network from operating or communicating.DSLShort for digital subscriber line, but is commonly used in reference to the asymmetric version of this technology (ADSL) that allows data to be sent over existing copper telephone lines at data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data (known as the upstream rate). ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world gain access. DSLAMDSL Access Multiplexor. The piece of equipment at the telephone company central office that provides the ADSL signal.Dynamic Host Configuration ProtocolDHCP. An Ethernet protocol specifying how a centralized DHCP server can assign network configuration information to multiple DHCP clients. The assigned information includes IP addresses, DNS addresses, and gateway (router) addresses.EAPExtensible Authentication Protocol is a general protocol for authentication that supports multiple authentication methods. EAP, an extension to PPP, supports such authentication methods as token cards, Kerberos, one-time passwords, certificates, public key authentication and smart cards. In wireless communications using EAP, a user requests connection to a WLAN through an AP, which then requests the identity of the user and
Reference Manual for the 54 Mbps Wireless Router WGR614 v54GlossaryJune 2004 202-10036-01transmits that identity to an authentication server such as RADIUS. The server asks the AP for proof of identity, which the AP gets from the user and then sends back to the server to complete the authentication. EAP is defined by RFC 2284.ESPEncapsulating Security Payload.ESSIDThe Extended Service Set Identification (ESSID) is a thirty-two character (maximum) alphanumeric key identifying the wireless local area network.

Reference Manual for the 54 Mbps Wireless Router WGR614 v58GlossaryJune 2004 202-10036-01SSIDA Service Set Identification is a thirty-two character (maximum) alphanumeric key identifying a wireless local area network. For the wireless devices in a network to communicate with each other, all devices must be configured with the same SSID. This is typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in the wireless Access Point and to the wireless network name. See also Wireless Network Name and ESSID.Subnet MaskA mask used to determine what subnet an IP address belongs to. Subnetting enables a network administrator to further divide an IP address into two or more subnets.An IP address has two components, the network address and the host address. For example, consider the IP address 150.215.017.009. Assuming this is part of a Class B network, the first two numbers (150.215) represent the Class B network address, and the second two numbers (017.009) identify a particular host on this network. Subnetting enables the network administrator to further divide the host part of the address into two or more subnets. In this case, a part of the host address is reserved to identify the particular subnet. This is easier to see if we show the IP address in binary format. The full address is: 10010110.11010111.00010001.00001001 The Class B network part is: 10010110.11010111 and the host address is 00010001.00001001 If this network is divided into 14 subnets, however, then the first 4 bits of the host address (0001) are reserved for identifying the subnet. The subnet mask is the network address plus the bits reserved for identifying the subnetwork. (By convention, the bits for the network address are all set to 1, though it would also work if the bits were set exactly as in the network address.) In this case, therefore, the subnet mask would be 11111111.11111111.11110000.00000000. It's called a mask because it can be used to identify the subnet to which an IP address belongs by performing a bitwise AND operation on the mask and the IP address. The result is the subnetwork address: Subnet Mask 255.255.240.000 11111111.11111111.11110000.00000000 IP Address 150.215.017.009 10010110.11010111.00010001.00001001 Subnet Address 150.215.016.000 10010110.11010111.00010000.00000000 The subnet address, therefore, is 150.215.016.000. TCP/IPThe main internetworking protocols used in the Internet. The Internet Protocol (IP) used in conjunction with the Transfer Control Protocol (TCP) form TCP/IP.TLSShort for Transport Layer Security, TLS is a protocol that guarantees privacy and data integrity between client/server applications communicating over the Internet. The TLS protocol is made up of two layers. The TLS Record Protocol ensures that a connection is private by using symmetric data encryption and ensures that the connection is reliable. The second TLS layer is the TLS Handshake Protocol, which allows authentication between the server and client and the negotiation of
