Regulatory Approvals FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communica-tions. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. (Example - use only shielded interface cables when connecting to computer or peripheral devices). FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. The antennas used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons. Channel The Wireless Channel sets the radio frequency used for communication. •Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference. • In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.) • If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join.The slot of the device Mobile Broadband Router will only accept and can only collocated with this PCMCIA Wireless Network Card, model: FPC-1000 (FCC ID:QZX99171001) manufactured by FLARION TECHNOLOGIES, INC., and and may not be collocated with any other radio cards About the PCMCIA Wireless Network Card,

Introduction 2-1202-10005-05, June 2005Chapter 2 IntroductionThis chapter describes the features of the NETGEAR 54 Mbps Mobile Broadband Router MBR814. The MBR814 router is a combination of a wireless broadband modem, router, 4-port switch, and firewall which enables your entire network to safely share an Internet connection.About the RouterThe 54 Mbps Mobile Broadband Router MBR814 provides continuous, high-speed 10/100 Ethernet access between your Ethernet devices. The MBR814 router enables your entire network to share an Internet connection through the wireless broadband modem that otherwise is used by a single computer. With minimum setup, you can install and use the router within minutes.The MBR814 router provides multiple Web content filtering options, plus e-mail browsing activity, reporting, and instant alerts. Parents and network administrators can establish restricted access policies based on time of day, Web site addresses, and address keywords. They can also share high-speed Internet access for up to 253 personal computers. The included firewall and Network Address Translation (NAT) features protect you from hackers.Key FeaturesThe MBR814 router provides the following features:• A powerful, true firewall.• 802.11g standards-based wireless networking.• Content filtering.• Auto Sensing and Auto Uplink™ LAN Ethernet connections.Note: If you are unfamiliar with networking and routing, refer to Appendix B, “Network and Routing Basics” to become more familiar with the terms and procedures used in this manual.

Reference Manual for the Broadband Mobile Router MBR8142-2 Introduction202-10005-05, June 2005• Easy, Web-based setup for installation and management.• Extensive Internet protocol support.• A card slot with PC card for wireless broadband access.These features are discussed below.802.11 Standards-based Wireless NetworkingThe MBR814 router includes an 802.11 g-compliant wireless access point, providing continuous, high-speed 10/100 Mbps access between your wireless and Ethernet devices. The access point provides:• 802.11 g Standards-based wireless networking at up to 100 Mbps.• Works with both 802.11g and 802.11b wireless devices.• 64-bit and 128-bit WEP encryption security.• WEP keys can be entered manually or generated by passphrase.• Support for the Wi-FI Protected Pre-Shared Key (WPA-PSK) encryption and 802.1x authentication.• Wireless access can be restricted by MAC address.A Powerful, True FirewallUnlike simple Internet sharing NAT routers, the MBR814 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 Denial of Service (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.• Logs security incidents The MBR814 will log security events such as blocked incoming traffic, port scans, attacks, and administrator logins. You can configure the router to email the log to you at specified intervals. You can also configure the router to send immediate alert messages to your email address or email pager whenever a significant event occurs.

Reference Manual for the Broadband Mobile Router MBR814Introduction 2-3202-10005-05, June 2005Content FilteringWith its content filtering feature, the MBR814 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.Auto Sensing and Auto Uplink™ LAN Ethernet ConnectionsWith its internal 4-port 10/100 switch, the MBR814 can connect to either a 10 Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN ports are autosensing and capable of full-duplex or half-duplex operation. The router incorporates Auto UplinkTM technology. Each local 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.Protocol SupportThe MBR814 supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing Information Protocol (RIP). Appendix B, “Network and Routing Basics” provides further information on TCP/IP.• The Ability to Enable or Disable IP Address Sharing by NAT The MBR814 allows several networked PCs 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 Network Address Translation (NAT), allows the use of an inexpensive single-user ISP account. This feature can also be turned off completely while using the MBR814 if you want to manage the IP address scheme yourself.• Automatic Configuration of Attached PCs by DHCP The MBR814 dynamically assigns network configuration information, including IP, router, and domain name server (DNS) addresses, to attached PCs on the LAN using the Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies configuration of PCs 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 PCs. The router obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN.

Reference Manual for the Broadband Mobile Router MBR8142-4 Introduction202-10005-05, June 2005• Classical IP (RFC 1577) Some Internet service providers, in Europe for example, use Classical IP in their ADSL services. In such cases, the router is able to use the Classical IP address from the ISP.• Dynamic DNS Dynamic DNS services allow remote users to find your network using a domain name when your IP address is not permanently assigned. The router contains a client that can connect to many popular Dynamic DNS services to register your dynamic IP address.• Universal Plug and Play (UPnP) UPnP is a networking architecture that provides compatibility between networking technologies. UPnP compliant routers provide broadband users at home and small businesses with a seamless way to participate in online games, videoconferencing and other peer-to-peer services. Easy Installation and ManagementYou can install, configure, and operate the MBR814 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.• Remote management The router allows you to log in to the Web management interface from a remote location via the Internet. For security, you can limit remote management access to a specified remote IP address or range of addresses, and you can choose a nonstandard port number.• Diagnostic functions The router incorporates built-in diagnostic functions such as Ping, DNS lookup, and remote reboot. These functions allow you to test Internet connectivity and reboot the router. You can use these diagnostic functions directly from the MBR814 when you are connected on the LAN or when you are connected over the Internet via the remote management function.• Visual monitoring The router’s front panel LEDs provide an easy way to monitor its status and activity.• Flash erasable programmable read-only memory (EPROM) for firmware upgrades.

You are now ready to configure your router to connect to the Internet. There are two ways you can configure your router to connect to the Internet:Unless your ISP automatically assigns your configuration automatically via DHCP, you need the configuration parameters from your ISP you recorded in “Record Your Internet Connection Information” on page 3-3.

Reference Manual for the Broadband Mobile Router MBR814Connecting the Router to the Internet 3-7202-10005-05, June 2005Testing Your Internet ConnectionAfter completing the Internet connection configuration, your can test your Internet connection. Log in to the router, then, from the Basic Settings link in the Setup menu, click the Test button. If the NETGEAR Web site does not appear within one minute, refer to Chapter 8, “Troubleshooting”.Your router is now configured to provide Internet access for your network. Your router automatically connects to the Internet when one of your computers requires access. It is not necessary to run a dialer or login application such as Dial-Up Networking or Enternet to connect, log in, or disconnect. These functions are performed by the router as needed.To access the Internet from any computer connected to your router, launch a browser such as Microsoft Internet Explorer or Netscape Navigator. You should see the router’s Internet LED blink, indicating communication to the ISP. The browser should begin to display a Web page.The following chapters describe how to configure the Advanced features of your router, and how to troubleshoot problems that may occur.Manually Configuring Your Internet Connection You can configure your router using the Basic Setup menu shown to the right, or you can allow the Setup Wizard to determine your configuration as described in the previous section.1. Set the WAN IP Address: • Select “Get Dynamically from ISP” if your ISP uses DHCP to assign your IP address. Your ISP will automatically assign these addresses.• Select “Use Static IP Address” if your ISP has assigned you a permanent, fixed (static) IP address. Enter the IP address that your ISP assigned. Also enter the IP Subnet Mask and the Gateway IP Address. The gateway is the ISP’s router to which your router will connect.

Reference Manual for the Broadband Mobile Router MBR8143-8 Connecting the Router to the Internet202-10005-05, June 20052. Specify the Domain Name Server (DNS) Address: • Select “Get Dynamically from ISP” if your ISP uses DHCP to assign your IP address. Your ISP will automatically assign this address.• If you know that your ISP does not automatically transmit DNS addresses to the router during login, select “Use these DNS servers” and enter the IP address of your ISP’s Primary DNS Server. If a Secondary DNS Server address is available, enter it also.A DNS server is a host on the Internet that translates Internet names (such as www.netgear.com) to numeric IP addresses. Typically your ISP transfers the IP address of one or two DNS servers to your router during login. If the ISP does not transfer an address, you must obtain it from the ISP and enter it manually here.3. You should only disable NAT if you are sure you do not require it. NAT automatically assigns private IP addresses (192.168.0.x) to LAN connected devices. When NAT is disabled, only standard routing is performed by this router. Classical routing lets you directly manage the IP addresses the MBR814 uses. Classical routing should be selected only by experienced users.Note: Disabling NAT will reboot the router and reset all the MBR814 configuration settings to the factory default. Disable NAT only if you plan to install the MBR814 in a setting where you will be manually administering the IP address space on the LAN side of the router4. Router MAC Address: This section determines the Ethernet MAC address that will be used by the router on the Internet port. Some ISPs will register the Ethernet MAC address of the network interface card in your computer when your account is first opened. They will then only accept traffic from the MAC address of that computer. This feature allows your router to masquerade as that computer by “cloning” its MAC address. To change the MAC address, select “Use this Computer’s MAC address”. The router will then capture and use the MAC address of the computer that you are now using. You must be using the one computer that is allowed by the ISP. Alternatively, select “Use this MAC address” and enter it.5. Click Apply to save your settings.6. Click the Test button to test your Internet connection. If the NETGEAR Web site does not appear within one minute, refer to Chapter 8, “Troubleshooting”.

Wireless Configuration 4-1Chapter 4 Wireless ConfigurationThis chapter describes how to configure the wireless features of your 54 Mbps Mobile Broadband Router MBR814.Considerations for a Wireless NetworkIn planning your wireless network, you should consider the level of security required. You should also select the physical placement of your router in order to maximize the network speed. For further information, 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 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 cordless phones• With the Antenna tight and in the upright position• Away from large metal surfacesNote: 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 Mobile Broadband Router MBR8144-2 Wireless ConfigurationThe 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.Implement Appropriate Wireless Security Unlike wired network data, your wireless data transmissions can extend beyond your walls and can be received by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The MBR814 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: MBR814 wireless data security optionsThere are several ways you can enhance the security of your wireless network:•Restrict Access Based on MAC Address. You can allow only trusted PCs to connect so that unknown PCs cannot wirelessly connect to the MBR814. Restricting access by MAC address 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 wireless network ‘discovery’ feature of some products, such as Windows XP, but the data is still exposed.Note: Indoors, computers can connect over 802.11g wireless networks at a maximum range of up to 300 feet. Such distances can allow for others outside of your immediate area to access your network.1) Open System: Easy but no security2) MAC Access List: No data security3) WEP: Security but some performance impactWireless DataSecurity OptionsRange: Up to 300 FeetMBR814

The Service Set ID, also known as the wireless network name. Enter a value of up to 32 alphanumeric characters. The same Name (SSID) must be assigned to all wireless devices in your network. The default SSID is NETGEAR, but NETGEAR strongly recommends that you change your network Name to a different value.

Reference Manual for the Mobile Broadband Router MBR814Wireless Configuration 4-5Note: This value is case sensitive. For example, Wireless is not the same as wireless.— Region. The region can not be changed by users —Mode. The default is "g & b", which allows both "g" and "b" wireless stations to access this device. “g only” allows only 802.11g wireless stations to be used. “b only” allows 802.11b wireless stations; 802.11g wireless stations can still be used if they can operate in 802.11b mode.•Wireless Access Point.—Enable Wireless Access Point. This field lets you turn off or turn on the wireless access point built in to the router. The wireless icon on the front of the router will also display the current status of the Wireless Access Point to let you know if it is disabled or enabled. The wireless access point must be enabled to allow wireless stations to access the Internet.—Allow Broadcast of Name (SSID). If enabled, the SSID is broadcast to all Wireless Stations. Stations which have no SSID (or a "null" value) can then adopt the correct SSID for connections to this Access Point.—Wireless Isolation. If enabled, Wireless Stations will not be able to communicate with each other or with Stations on the wired network. This feature should normally be disabled.• Wireless Station Access List.— By default, any wireless computer that is configured with the correct wireless network name or SSID will be allowed access to your wireless network. For increased security, you can restrict access to the wireless network to only specific computers based on their MAC addresses.

Since the trusted user will be identified by an IP address, you should configure that computer with a fixed IP address.7. Click Apply to save your settings.Firewall RulesFirewall rules are used to block or allow specific traffic passing through from one side of the router to the other. Inbound rules (WAN to LAN) restrict access by outsiders to private resources, selectively allowing only specific outside users to access specific resources. Outbound rules (LAN to WAN) determine what outside resources local users can have access to.A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of the MBR814 are:• Inbound: Block all access from outside except responses to requests from the LAN side.• Outbound: Allow all access from the LAN side to the outside.You can define additional rules that will specify exceptions to the default rules. By adding custom rules, you can block or allow access based on the service or application, source or destination IP addresses, and time of day. You can also choose to log traffic that matches or does not match the rule you have defined.You can change the order of precedence of rules so that the rule that applies most often will take effect first. See “Order of Precedence for Rules” on page 5-11 for more details.To access the rules configuration of the MBR814, click the Firewall Rules link on the main menu, then click Add for either an Outbound or Inbound Service.

At the script prompt, enter the number of the desired new position and click OK.Inbound Rules (Port Forwarding)Because the MBR814 uses Network Address Translation (NAT), your network presents only one IP address to the Internet, and outside users cannot directly address any of your local computers. However, by defining an inbound rule you can make a local server (for example, a Web server or game server) visible and available to the Internet. The rule tells the router to direct inbound traffic for a particular service to one local server based on the destination port number. This is also known as port forwarding.Remember that allowing inbound services opens holes in your firewall. Only enable those ports that are necessary for your network. Following are two application examples of inbound rules:Note: Some residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to the Acceptable Use Policy of your ISP.

Reference Manual for the Broadband Mobile Router MBR814Protecting Your Network 5-7202-10005-05, June 2005Inbound Rule Example: A Local Public Web ServerIf you host a public Web server on your local network, you can define a rule to allow inbound Web (HTTP) requests from any outside IP address to the IP address of your Web server at any time of day. This rule is shown in Figure 5-5:Figure 5-5: Rule example: A Local Public Web ServerThe parameters are:•Service From this list, select the application or service to be allowed or blocked. The list already displays many common services, but you are not limited to these choices. Use the Services menu to add any additional services or applications that do not already appear.• Action Choose how you want this type of traffic to be handled. You can block or allow always, or you can choose to block or allow according to the schedule you have defined in the Schedule menu.• Send to LAN Server Enter the IP address of the computer or server on your LAN which will receive the inbound traffic covered by this rule.• WAN Users These settings determine which packets are covered by the rule, based on their source (WAN) IP address. Select the desired option:

Reference Manual for the Broadband Mobile Router MBR8145-8 Protecting Your Network202-10005-05, June 2005– Any — all IP addresses are covered by this rule. – Address range — if this option is selected, you must enter the Start and Finish fields. – Single address — enter the required address in the Start field. •Log You can select whether the traffic will be logged. The choices are:– Never — no log entries will be made for this service.– Always — any traffic for this service type will be logged.– Match — traffic of this type which matches the parameters and action will be logged.– Not match — traffic of this type which does not match the parameters and action will be logged.Inbound Rule Example: Allowing VideoconferencingIf you want to allow incoming videoconferencing to be initiated from a restricted range of outside IP addresses, such as from a branch office, you can create an inbound rule. In the example shown in Figure 5-6, CU-SeeMe connections are allowed only from a specified range of external IP addresses. In this case, we have also specified logging of any incoming CU-SeeMe requests that do not match the allowed parameters.Figure 5-6: Rule example: Videoconference from Restricted Addresses

Reference Manual for the Broadband Mobile Router MBR814Protecting Your Network 5-9202-10005-05, June 2005Considerations for Inbound Rules• If your external IP address is assigned dynamically by your ISP, the IP address may change periodically as the DHCP lease expires. Consider using the Dynamic DNS feature in the Advanced menu so that external users can always find your network.• If the IP address of the local server computer is assigned by DHCP, it may change when the computer is rebooted. To avoid this, use the Reserved IP address feature in the LAN IP menu to keep the computer’s IP address constant.• Local computers must access the local server using the computer’s local LAN address (192.168.0.11 in the example in Figure 5-6 above). Attempts by local computers to access the server using the external WAN IP address will fail.Outbound Rules (Service Blocking)The MBR814 allows you to block the use of certain Internet services by computers on your network. This is called service blocking or port filtering. You can define an outbound rule to block Internet access from a local computer based on:• IP address of the local computer (source address)• IP address of the Internet site being contacted (destination address)•Time of day• Type of service being requested (service port number)Following is an application example of outbound rules:Outbound Rule Example: Blocking Instant MessengerIf you want to block Instant Messenger usage by employees during working hours, you can create an outbound rule to block that application from any internal IP address to any external address according to the schedule that you have created in the Schedule menu. You can also have the router log any attempt to use Instant Messenger during that blocked period.

The list already displays many common services, but you are not limited to these choices. Use the Add Custom Service feature to add any additional services or applications that do not already appear.• Action Choose how you want this type of traffic to be handled. You can block or allow always, or you can choose to block or allow according to the schedule you have defined in the Schedule menu.• LAN Users These settings determine which packets are covered by the rule, based on their source LAN IP address. Select the desired option: – Any — all IP addresses are covered by this rule. – Address range — if this option is selected, you must enter the Start and Finish fields. – Single address — enter the required address in the Start field.

Select the desired option: – Any — all IP addresses are covered by this rule. – Address range —if this option is selected, you must enter the Start and Finish fields. – Single address — enter the required address in the Start field. •Log You can select whether the traffic will be logged. The choices are:– Never — no log entries will be made for this service.– Always — any traffic for this service type will be logged.– Match — traffic of this type that matches the parameters and action will be logged.– Not match — traffic of this type that does not match the parameters and action will be logged.Order of Precedence for RulesAs you define new rules, they are added to the tables in the Rules menu, as shown in Figure 5-8:Figure 5-8: Rules table with examples

Reference Manual for the Broadband Mobile Router MBR8145-12 Protecting Your Network202-10005-05, June 2005For any traffic attempting to pass through the firewall, the packet information is subjected to the rules in the order shown in the Rules Table, beginning at the top and proceeding to the default rules at the bottom. In some cases, the order of precedence of two or more rules may be important in determining the disposition of a packet. The Move button allows you to relocate a defined rule to a new position in the table.ServicesServices 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 the Internet sends a request for service to a server computer, 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.The service numbers for many common protocols are defined by the Internet Engineering Task Force (IETF) and published in RFC1700, “Assigned Numbers.” Service numbers for other applications are typically chosen from the range 1024 to 65535 by the authors of the application.Although the MBR814 already holds a list of many service port numbers, you are not limited to these choices. Use the procedure below to create your own service definitions.How to Define Services1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever Password and LAN address you have chosen for the router.2.

Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever User Name, Password and LAN address you have chosen for the router.2. From the Advanced section of the main menu, select the Remote Management link.3. Select the Turn Remote Management On check box.4. Specify what external addresses will be allowed to access the router’s remote management. For security, restrict access to as few external IP addresses as practical:• To allow access from any IP address on the Internet, select Everyone. • 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. • To allow access from a single IP address on the Internet, select Only this Computer. Enter the IP address that will be allowed access. 5. 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, you can 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.6. Click Apply to have your changes take effect.Note: Be sure to change the router's default 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 Broadband Mobile Router MBR814Managing Your Network 6-15202-10005-05, June 2005When accessing your router from the Internet, you will type your router's WAN IP address in 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, enter in your browser:http://134.177.0.123:8080Note: In this case, the http:// must be included in the address.

Advanced Configuration 7-1202-10005-05, June 2005Chapter 7 Advanced Configuration This chapter describes how to configure the advanced features of your 54Mbps Mobile Broadband Router MBR814. Configuring Advanced SecurityThe 54Mbps Mobile Broadband Router MBR814 provides a variety of advanced features, such as:• Setting up a Demilitarized Zone (DMZ) Server• Connecting Automatically, as Required• Disabling Port Scan and DOS Protection• Responding to a Ping on the Internet WAN Port•MTU Size • Flexibility on configuring your LAN TCP/IP settings• Using the Router as a DHCP Server• Configuring Dynamic DNS• Configuring Static RoutesThese features are discussed below.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.

Reference Manual for the Broadband Mobile Router MBR8147-2 Advanced Configuration202-10005-05, June 2005Incoming 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.How to Configure a Default DMZ ServerTo assign a computer or server to be a Default DMZ server, follow these steps: 1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever Password and LAN address you have chosen for the router.2. From the Main Menu, under Advanced, click the WAN Setup link to view the page shown in Figure 7-1:Figure 7-1: WAN Setup Page3. Select the Default DMZ Server check box.4. Type the IP address for that server. 5. Click Apply to save your changes. Note: For security reasons, you should avoid using the Default DMZ Server feature. When a computer is designated as the Default DMZ Server, it loses much of the protection of the firewall, and is exposed to many exploits from the Internet. If compromised, the computer can be used to attack your network.

Reference Manual for the Broadband Mobile Router MBR814Advanced Configuration 7-3202-10005-05, June 2005Connect Automatically, as Required Normally, this option should be enabled, so that an Internet connection will be made automatically, whenever Internet-bound traffic is detected. If this causes high connection costs, you can disable this setting. If disabled, you must connect manually, using the sub-screen accessed from the "Connection Status" button on the Status screen.If you have an "Always on" connection, this setting has no effect.Disable Port Scan and DOS ProtectionThe Firewall protects your LAN against Port Scans and Denial of Service (DOS) attacks. This should be disabled only in special circumstances.Respond to Ping on Internet WAN Port If you want the router to respond to a 'ping' from the Internet, select 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. Do not select this box unless you have a specific reason to do so.MTU Size The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes, or 1492 Bytes for PPPoE 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.Configuring LAN IP SettingsThe LAN IP Setup menu allows configuration of LAN IP services such as DHCP and RIP. These features can be found under the Advanced heading in the Main Menu of the browser interface.The 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—255.255.255.0These addresses are part of the Internet Engineering Task Force (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.

Reference Manual for the Broadband Mobile Router MBR8147-4 Advanced Configuration202-10005-05, June 2005Figure 7-2: LAN IP Setup MenuThe LAN TCP/IP Setup 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.

Reference Manual for the Broadband Mobile Router MBR814Advanced Configuration 7-5202-10005-05, June 2005— 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. Both RIP-2B and RIP-2M send the routing data in RIP-2 format. — RIP-2B uses subnet broadcasting. — RIP-2M uses multicasting.DHCPBy 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 PCs 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 “IP Configuration by DHCP”on page B-9 for an explanation of DHCP and information about how to assign IP addresses for your network. Use Router as DHCP serverIf 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 selected. 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 192.168.0.254, although you may want 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 is the router’s LAN IP addressNote: 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 Broadband Mobile Router MBR8147-6 Advanced Configuration202-10005-05, June 2005• 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 menu• WINS Server, short for Windows Internet Naming Service Server, determines the IP address associated with a particular Windows computer. A WINS server records and reports a list of names and IP address of Windows PCs on its local network. If you connect to a remote network that contains a WINS server, enter the server’s IP address here. This allows your PCs to browse the network using the Network Neighborhood feature of Windows.Reserved IP addressesWhen 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. 2. 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. How to Configure LAN TCP/IP Settings1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever User Name, Password and LAN address you have chosen for the router.

Reference Manual for the Broadband Mobile Router MBR814Advanced Configuration 7-7202-10005-05, June 20052. From the Main Menu, under Advanced, click the LAN IP Setup link to view the menu, shown in Figure 7-3:.Figure 7-3: LAN IP Setup Menu3. Enter the TCP/IP, DHCP, or Reserved IP parameters.4. Click Apply to save your changes.Configuring Dynamic DNSIf 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 that 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 a dynamic DNS service provider. To use this feature, you must select a service provider and obtain an account with them. After you have configured your account information in the router, 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.

Reference Manual for the Broadband Mobile Router MBR8147-8 Advanced Configuration202-10005-05, June 2005How to Configure Dynamic DNS1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever User Name, Password and LAN address you have chosen for the router.2. From the Main Menu of the browser interface, under Advanced, select Dynamic DNS to display the page below.Figure 7-4: Dynamic DNS menu3. Access the Web site of one of the dynamic DNS service providers whose names appear in the ‘Service Provider’ box, and register for an account. For example, for dyndns.org, go to www.dyndns.org.4. Select the “Use a dynamic DNS service” check box. 5. Select the name of your dynamic DNS Service Provider. 6. Type the Host Name that your dynamic DNS service provider gave you. The dynamic DNS service provider may call this the domain name. If your URL is myName.dyndns.org, then your Host Name is “myName.”7. Type the User Name for your dynamic DNS account. 8. Type the Password (or key) for your dynamic DNS account. 9. If your dynamic DNS provider allows the use of wildcards in resolving your URL, you can 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.org

Using 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.Static Route ExampleAs 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.When you first configured your router, two implicit static routes were created. A default route was created with your ISP as the router, 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 7-6.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 Router IP Address fields specifies that all traffic for these addresses should be forwarded to the ISDN router at 192.168.0.100. 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 Broadband Mobile Router MBR8147-10 Advanced Configuration202-10005-05, June 2005• A Metric value of 1 will work since the ISDN router is on the LAN. This represents the number of routers between your network and the destination. This is a direct connection so it is set to 1.• Private is selected only as a precautionary security measure in case RIP is activated.How to Configure Static Routes1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever User Name, Password and LAN address you have chosen for the router.2. From the Main Menu of the browser interface, under Advanced, click Static Routes to view the Static Routes menu, shown in Figure 7-5. Figure 7-5: Static Routes Table3. To add or edit a Static Route:a. Click the Edit button to open the Edit Menu, shown in Figure 7-6.Figure 7-6: Static Route Entry and Edit Menu

Reference Manual for the Broadband Mobile Router MBR814Advanced Configuration 7-11202-10005-05, June 2005b. Type a route name for this static route in the Route Name box under the table. This is for identification purpose only. c. Select Private if you want to limit access to the LAN only. The static route will not be reported in RIP. d. Select Active to make this route effective. e. Type the Destination IP Address of the final destination. f. Type the IP Subnet Mask for this destination. If the destination is a single host, type 255.255.255.255. g. Type the Gateway IP Address, which must be a router on the same LAN segment as the router. h. 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. 4. Click Apply to have the static route entered into the table. 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.1. Click UPnP on the main menu to invoke the UPnP menu:Figure 7-7: Universal Plug and Play menu

Reference Manual for the Broadband Mobile Router MBR8147-12 Advanced Configuration202-10005-05, June 20052. Fill out the UPnP screen:•Turn UPnP O n : UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP is enabled. If disabled, the Router will not allow any device to automatically control the resources, such as port forwarding (mapping), of the Router. •Advertisement Period: The Advertisement Period is how often the Router will advertise (broadcast) its UPnP information. This value can range from 1 to 1440 minutes. The default period is for 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. A hop is the number of steps 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. 3. To save, cancel or refresh the table:a. Click Apply to save the new settings to the Router. b. Click Cancel to disregard any unsaved changes. c. Click Refresh to update the portmap table and to show the active ports that are currently opened by UPnP devices.

Troubleshooting 8-1202-10005-05, June 2005Chapter 8 TroubleshootingThis chapter gives information about troubleshooting your 54Mbps Mobile Broadband Router MBR814. After each problem description, instructions are provided to help you diagnose and solve the problem. For the common problems listed, go to the section indicated.• Is the router on?• Have I connected the router correctly?Go to “Basic Functioning” on page 8-1.• I can’t access the router’s configuration with my browser.Go to “Troubleshooting the Web Configuration Interface” on page 8-3.• I’ve configured the router but I can’t access the Internet.Go to “Troubleshooting the ISP Connection” on page 8-4.• I can’t remember the router’s configuration password.• I want to clear the configuration and start over again.Go to “Restoring the Default Configuration and Password” on page 8-7.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 LED is on (see “The Router’s Front Panel” on page 2-5 for an illustration and explanation of the LEDs).2. Verify that the Test LED lights within a few seconds, indicating that the self-test procedure is running.3. After approximately 10 seconds, verify that:a. The Test LED is not lit.b. The LAN port LEDs are lit for any local ports that are connected.c. The WAN port LED is lit.

Reference Manual for the Broadband Mobile Router MBR8148-2 Troubleshooting202-10005-05, June 2005If a port’s LED 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 LED is green. If the port is 10 Mbps, the LED will be amber.If any of these conditions does not occur, refer to the appropriate following section.Power LED Not OnIf the Power and other LEDs 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 power adapter supplied by NETGEAR for this product.If the error persists, you have a hardware problem and should contact technical support.Test LED Never Turns On or Test LED Stays OnWhen the router is turned on, the Test LED turns on for about 10 seconds and then turns off. If the Test LED does not turn on, or if it stays on, there is a fault within the router.If you experience problems with the Test LED:• Cycle the power to see if the router recovers and the LED blinks for the correct amount of time.If all LEDs including the Test LED 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 “Using the Reset button” on page 8-7.If the error persists, you might have a hardware problem and should contact technical support.LAN or WAN Port LEDs Not OnIf either the LAN LEDs or WAN LED 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 the wireless broadband PC card is inserted properly.

Reference Manual for the Broadband Mobile Router MBR814Troubleshooting 8-3202-10005-05, June 2005Troubleshooting 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:• If you are using an Ethernet-connected computer, 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-6 or “Verifying TCP/IP Properties for Macintosh Computers” on page C-17 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 was changed and you do not 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 “Using the Reset button” 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 Broadband Mobile Router MBR8148-4 Troubleshooting202-10005-05, June 2005Troubleshooting the ISP ConnectionIf your router is unable to access the Internet, you should check the ADSL connection, then the WAN TCP/IP connection. ADSL linkIf your router is unable to access the Internet, you should first determine whether you have an ADSL link with the service provider. The state of this connection is indicated with the WAN LED.Internet LED Green or Blinking GreenIf your Internet LED is green or blinking green, then you have a good broadband connection. You can be confident that the service provider has connected your line correctly and that your wiring is correct.Internet LED OffIf the Internet LED is off, disconnect the power to the router. Ensure the wireless broadband PC card is inserted properly and re-connect the power to the router.If the problem persists, the wireless coverage in your area may be poor or the PC card may be defective.Obtaining an Internet IP AddressIf your router is unable to access the internet, and your Internet LED is green or blinking green, you should determine whether the router is able to obtain a Internet 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 browser interface.To check the WAN IP address from the browser interface: 1. Launch your browser and select an external site such as www.netgear.com.2. Access the Main Menu of the router’s configuration at http://192.168.0.1. 3. Under the Maintenance heading 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, the problem may be one of the following:

Reference Manual for the Broadband Mobile Router MBR814Troubleshooting 8-5202-10005-05, June 2005• Your ISP may check for your computer's host name. Assign the computer Host Name of your ISP account to the router in the browser-based Setup Wizard.• You have poor wireless coverage.• Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for your computer’s MAC address. In this case:Inform 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 “Manually Configuring Your Internet Connection” on page 3-7.Troubleshooting Internet BrowsingIf 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 “Verifying TCP/IP Properties” on page C-6. Alternatively, you can 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 router.If your computer obtains its information from the router by DHCP, reboot the computer and verify the router address as described in “Verifying TCP/IP Properties” on page C-6.Troubleshooting a TCP/IP Network Using the 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.

Reference Manual for the Broadband Mobile Router MBR8148-6 Troubleshooting202-10005-05, June 2005Testing 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 PC running Windows 95 or later:1. From the Windows toolbar, click 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 192.168.0.13. Click 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 LEDs 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 PC 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 PC to a remote device. From the Windows run menu, type:PING -n 10 <IP address>

Reference Manual for the Broadband Mobile Router MBR814Troubleshooting 8-7202-10005-05, June 2005where <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 PC has the IP address of your router listed as the default router. If the IP configuration of your PC is assigned by DHCP, this information will not be visible in your PC’s Network Control Panel. Verify that the IP address of the router is listed as the default router as described in “Verifying TCP/IP Properties” on page C-6.— Check to see that the network address of your PC (the portion of the IP address specified by the netmask) is different from the network address of the remote device.— Check that your wireless broadband PC card is installed properly.— If your ISP assigned a host name to your PC, 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 PCs. 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 PC connected to that modem. If this is the case, you must configure your router to “clone” or “spoof” the MAC address from the authorized PC. Refer to “Manually Configuring Your Internet Connection” on page 3-7.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 Web Configuration Manager (see “Backing Up, Restoring, or Erasing Your Settings” on page 6-1).• 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.Using the Reset buttonTo 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 Test LED turns on (about 10 seconds).2. Release the Default Reset button and wait for the router to reboot.

Reference Manual for the Broadband Mobile Router MBR8148-8 Troubleshooting202-10005-05, June 2005Problems with Date and TimeThe E-mail menu in the Content Filtering section displays the current date and time of day. The MBR814 router uses the Network Time Protocol (NTP) to obtain the current time from one of several Network Time Servers on the Internet. Each entry in the log is stamped with the date and time of day. Problems with the date and time function can include:• Date shown is January 1, 2000 Cause: The router has not yet successfully reached a Network Time Server. Check that your Internet access settings are configured correctly.

Network and Routing Basics B-1202-10005-05, June 2005Appendix BNetwork and Routing BasicsThis chapter provides an overview of IP networks and routing.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 54Mbps Mobile Broadband Router MBR814 is a small office router that routes the IP protocol over a single-user broadband connection.

Reference Manual for the Broadband Mobile Router MBR814B-2 Network and Routing Basics202-10005-05, June 2005Routing 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 MBR814 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 Broadband Mobile Router MBR814Network and Routing Basics B-3202-10005-05, June 2005Figure 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. Class ANetwork NodeClass BClass CNetwork NodeNetwork Node

Reference Manual for the Broadband Mobile Router MBR814B-4 Network and Routing Basics202-10005-05, June 2005This 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 Broadband Mobile Router MBR814Network and Routing Basics B-5202-10005-05, June 2005Subnet 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.The 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.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 Broadband Mobile Router MBR814Network and Routing Basics B-7202-10005-05, June 2005When a device broadcasts to its segment neighbors, it uses a destination address of the local network address with all ones for the host address. 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 - 192.168.255.255NETGEAR recommends that you choose your private network number from this range. The DHCP server of the MBR814 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 PCs 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 MBR814 router employs an address-sharing method called Network Address Translation (NAT). This method allows several networked PCs 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).The following figure illustrates a single IP address operation.

Reference Manual for the Broadband Mobile Router MBR814B-8 Network and Routing Basics202-10005-05, June 2005 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 PC (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.If 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. 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 Broadband Mobile Router MBR814Network and Routing Basics B-9202-10005-05, June 2005Related 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 PC accesses a resource by its descriptive name, it first contacts a DNS server to obtain the IP address of the resource. The PC 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.IP Configuration by DHCPWhen an IP-based local area network is installed, each PC must be configured with an IP address. If the PCs 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 PC 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 MBR814 router has the capacity to act as a DHCP server.

Reference Manual for the Broadband Mobile Router MBR814B-10 Network and Routing Basics202-10005-05, June 2005The MBR814 router also functions as a DHCP client when connecting to the ISP. The router 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 Network Address Translation (NAT) process, the network behind the NAT 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 email 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.Stateful 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.

Reference Manual for the Broadband Mobile Router MBR814Network and Routing Basics B-11202-10005-05, June 2005Denial 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.Category 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.

(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.Inside Twisted Pair CablesFor two devices to communicate, the transmitter of each device must be connected to the receiver of the other device. 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.

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 PC, which is wired as Media Dependant Interface (MDI). In this wiring, the PC 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).

Reference Manual for the Broadband Mobile Router MBR814B-14 Network and Routing Basics202-10005-05, June 2005When connecting a PC to a PC, 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 blue pairs will be exchanged from one connector to the other.The MBR814 router incorporates Auto UplinkTM technology (also called MDI/MDIX). 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 PC) 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-1202-10005-05, June 2005Appendix CPreparing Your NetworkThis appendix describes how to prepare your network to connect to the Internet through the 54Mbps Mobile Broadband Router MBR814 and how to verify the readiness of broadband Internet service from an Internet service provider (ISP).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 PC, then TCP/IP is probably already installed as well.Most 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.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 router. Write down this information before reconfiguring your computers. Refer to “Obtaining ISP Configuration Information for Windows Computers” on page C-19 or “Obtaining ISP Configuration Information for Macintosh Computers” on page C-20 for further information.

Reference Manual for the Broadband Mobile Router MBR814C-2 Preparing Your Network202-10005-05, June 2005In your IP network, each PC and the router must be assigned a unique IP addresses. Each PC 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 PC 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 and Routing Basics.” The MBR814 router is shipped preconfigured as a DHCP server. The router 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 router)—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. Before starting, locate your Windows CD; you may need to insert it during the TCP/IP installation process.Installing or Verifying Windows Networking ComponentsTo install or verify the necessary components for IP networking:1.
