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 communications. 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.
About the PCMCIA Wireless Network Card,
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

Introduction
This 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.
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.
About the Router
The 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 Features
The 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.

Content Filtering
With 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 Connections
With 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 Support
The 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.

•
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 Management
You 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.
•

Testing Your Internet Connection
After 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.
Connecting the Router to the Internet

Reference Manual for the Broadband Mobile Router MBR814
2. 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 router
4. 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
This chapter describes how to configure the wireless features of your 54 Mbps Mobile Broadband
Router MBR814.
Considerations for a Wireless Network
In 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 Guidelines
The 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.
Note: Failure to follow these guidelines can result in significant performance
degradation or inability to wirelessly connect to the router. For complete range/
performance specifications, please see Appendix A, “Technical Specifications”.
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 surfaces
Wireless Configuration

Reference Manual for the Mobile Broadband Router MBR814
The time it takes to establish a wireless connection can vary depending on both your security
settings and placement. WEP connections can take slightly longer to establish. Also, WEP
encryption can consume more battery power on a notebook computer.
Implement Appropriate Wireless Security
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.
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.

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.

WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared
Key authentication and WEP data encryption will block all but the most determined
eavesdropper.
•
WPA-PSK. Wi-Fi Protected Access (WPA) data encryption provides data security. The very
strong authentication along with dynamic per frame re-keying of WPA make it virtually
impossible to compromise. Because this is a new standard, wireless device driver and software
availability may be limited.

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

match the firewall’s new settings.
8. Configure and test your computers for wireless connectivity.
Program the wireless adapter of your computers to have the same SSID and channel that you
configured in the router. Check that they have a wireless link and are able to obtain an IP
address by DHCP from the firewall.
Once your computers have basic wireless connectivity to the firewall, you can configure the
advanced wireless security functions of the firewall.
How to Restricting Wireless Access to Your Network
By default, any wireless PC that is configured with the correct SSID will be allowed access to your
wireless network. For increased security, the 54 Mbps Mobile Broadband Router MBR814
provides several ways to restrict wireless access to your network:
•
Turn off wireless connectivity completely
•
Restrict access based on the Wireless Network Name (SSID)

Figure 4-3: Wireless Access Point settings
Restricting Access to Your Network by Turning Off Wireless Connectivity
You can completely turn off the wireless portion of the MBR814. For example, if your notebook
computer is used to wirelessly connect to your router and you take a business trip, you can turn off
the wireless portion of the router while you are traveling. Other members of your household who
use computers connected to the router via Ethernet cables will still be able to use the router.
Restricting Wireless Access Based on the Wireless Network Name (SSID)
The MBR814 can restrict wireless access to your network by not broadcasting the wireless
network name (SSID). However, by default, this feature is turned off. If you turn this feature on,
wireless devices will not ‘see’ your MBR814. You must configure your wireless devices to match
the wireless network name (SSID) you configure in the MBR814 router.
Note: The SSID of any wireless access adapters must match the SSID you configure in the 54
Mbps Mobile Broadband Router MBR814. If they do not match, you will not get a wireless
connection to the MBR814.
Restricting Wireless Access Based on the Wireless Station Access List
This list determines which wireless hardware devices will be allowed to connect to the firewall.
To restrict access based on MAC addresses, follow these steps:
1. Log in to the MBR814 firewall at its default LAN address of http://192.168.0.1 with its default
user name of admin and default password of password, or using whatever LAN address and
password you have set up.
2. From the Wireless Settings menu, Wireless Station Access List section, click the Setup Access
List button to display the list, shown below:
Wireless Configuration

Reference Manual for the Mobile Broadband Router MBR814
Figure 4-4: Wireless Access menu
3. Select the Turn Access Control On check box to enable restricting wireless computers by their
MAC addresses.
4. If the wireless station is currently connected to the network, you can select it from the
Available Wireless Stations list. Click Add to add the station to the Trusted Wireless Stations
list.
5. If the wireless station is not currently connected, you can enter its address manually. Enter the
MAC address of the authorized computer. The MAC address is usually printed on the wireless
card, or it may appear in the router’s DHCP table. The MAC address will be 12 hexadecimal
digits.
Click Add to add your entry. You can add several stations to the list, but the entries will be
discarded if you do not click Apply.
Note: You can copy and paste the MAC addresses from the router’s Attached Devices menu
into the MAC Address box of this menu. To do this, configure each wireless computer to
obtain a wireless link to the router. The computer should then appear in the Attached Devices
menu.

Reference Manual for the Mobile Broadband Router MBR814
Note: If you are configuring the router from a wireless computer whose MAC address is
not in the Trusted Wireless Stations list, and you select Trusted Wireless Stations only,
you will lose your wireless connection when you click Apply. You must then access the
router from a wired computer to make any further changes.
6. Make sure the Turn Access Control On check box is selected, then click Apply.
Now, only devices on this list will be allowed to wirelessly connect to the MBR814. This prevents
unauthorized access to your network.
Choosing WEP Authentication and Security Encryption Methods
Figure 4-5.
Security Encryption section
Restricting wireless access prevents intruders from connecting to your network. However, the
wireless data transmissions are still vulnerable to snooping. Using the WEP data encryption
settings described below will prevent a determined intruder from eavesdropping on your wireless
data communications. Also, if you are using the Internet for such activities as purchases or
banking, those Internet sites use another level of highly secure encryption called SSL. You can tell
if a web site is using SSL because the web address begins with HTTPS rather than HTTP.
Authentication Type Selection
The MBR814 lets you select the following wireless authentication schemes.

Note: The authentication scheme is separate from the data encryption. You can choose
an authentication scheme which requires a shared key but still leave the data
transmissions unencrypted. If you require strong security, use both the Shared Key and
WEP encryption settings.
Set your wireless adapter according to the authentication scheme you choose for the MBR814
router. Please refer to “Authentication and WEP Data Encryption” on page D-2 for a full
explanation of each of these options, as defined by the IEEE 802.11g wireless communication
standard.
Encryption Choices
Please refer to “Overview of WEP Parameters” on page D-5 for a full explanation of each of the
following choices, as defined by the IEEE 802.11g wireless communication standard. Choose the
encryption strength from the drop-down list:
Disable. No encryption will be applied. This setting is useful for troubleshooting your wireless
connection, but leaves your wireless data fully exposed.
64 or 128 bit WEP. When 64 Bit WEP or 128 Bit WEP is selected, WEP encryption will be
applied.
If WEP is enabled, you can manually or automatically program the four data encryption keys.
These values must be identical on all computers and access points in your network.
There are two methods for creating WEP encryption keys:
•
Passphrase. Enter a word or group of printable characters in the Passphrase box and click the
Generate button.
•
Manual. 64-bit WEP: Enter 10 hexadecimal digits (any combination of 0-9, a-f, or A-F).

For security reasons, the router has its own user name and password. Also, after a period of
inactivity for a set length of time, the administrator login will automatically disconnect. When
prompted, enter admin for the router User Name and password for the router Password. You can
use procedures below to change the router's password and the amount of time for the
administrator’s login timeout.
Note: The user name and password are not the same as any user name or password your may use
to log in to your Internet connection.
NETGEAR recommends that you change this password to a more secure password. The ideal
password should contain no dictionary words from any language, and should be a mixture of both
upper and lower case letters, numbers, and symbols. Your password can be up to 30 characters.
How to Change the Built-In Password
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.

Blocking Keywords, Sites, and Services
The router provides a variety of options for blocking Internet based content and communications
services. With its content filtering feature, the MBR814 router prevents objectionable content from
reaching your PCs. The router allows you to control access to Internet content by screening for
keywords within Web addresses. Key content filtering options include:
•
Keyword blocking of HTTP traffic.
•
Outbound Service Blocking limits access from your LAN to Internet locations or services that
you specify as off-limits.
•
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.
•
Blocking unwanted traffic from the Internet to your LAN.
The section below explains how to configure your router to perform these functions.
How to Block Keywords and Sites
The MBR814 router allows you to restrict access to Internet content based on functions such as
Web addresses and Web address keywords.
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. Select the Block Sites link of the Security menu.

Firewall Rules
Firewall 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.

To edit an existing rule, select its button on the left side of the table and click Edit.
To delete an existing rule, select its button on the left side of the table and click Delete.
To move an existing rule to a different position in the table, select its button on the left side
of the table and click Move. 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.
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.
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:

Protecting Your Network
Reference Manual for the Broadband Mobile Router MBR814
Inbound Rule Example: A Local Public Web Server
If 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:

–
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

Inbound Rule Example: Allowing Videoconferencing
If 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.

Protecting Your Network
Reference Manual for the Broadband Mobile Router MBR814
Considerations 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 Messenger
If 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.

Figure 5-8: Rules table with examples
Protecting Your Network
202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814
For 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.
Services
Services 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 Services

How to Upgrade the Router Firmware
Note: NETGEAR recommends that you back up your configuration before doing a firmware
upgrade. After the upgrade is complete, you may need to restore your configuration settings.
1.
Download and unzip the new software file from NETGEAR.
The Web browser used to upload new firmware into the router must support HTTP uploads.
NETGEAR recommends using Microsoft Internet Explorer 5.0 or above, or Netscape
Navigator 4.7 or above.
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.
3.
From the Main Menu of the browser interface, under the Maintenance heading, select the
Router Upgrade heading to display the menu shown in Figure 6-2.
Figure 6-2: Router Upgrade menu
4.
In the Router Upgrade menu, click the Browse to locate the binary (.BIN or .IMG) upgrade
file.
5.
Click Upload.
Note: When uploading software to the router, it is important not to interrupt the Web
browser by closing the window, clicking a link, or loading a new page. If the browser is
interrupted, it may corrupt the software. When the upload is complete, your router will
automatically restart. The upgrade process will typically take about one minute. In some
cases, you may need to clear the configuration and reconfigure the router after
upgrading.

Enabling Remote Management
Using the Remote Management page, you can allow a user or users on the Internet to configure,
upgrade and check the status of your 54Mbps Mobile Broadband Router MBR814.
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.
Configuring Remote Management
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 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.

Chapter 7
Advanced Configuration
This chapter describes how to configure the advanced features of your 54Mbps Mobile Broadband
Router MBR814.
Configuring Advanced Security
The 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 Routes
These features are discussed below.
Setting Up A Default DMZ Server
The 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.
Advanced Configuration
202-10005-05, June 2005
7-1
Reference Manual for the Broadband Mobile Router MBR814
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.
Incoming traffic from the Internet is normally discarded by the router unless the traffic is a
response to one of your local computers or a service that you have configured in the Ports menu.
Instead of discarding this traffic, you can have it forwarded to one computer on your network. This
computer is called the Default DMZ Server.
How to Configure a Default DMZ Server
To 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 Page
3. Select the Default DMZ Server check box.
4. Type the IP address for that server.
5. Click Apply to save your changes.
7-2
202-10005-05, June 2005
Advanced Configuration
Reference Manual for the Broadband Mobile Router MBR814
Connect 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 Protection
The 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 Settings
The 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—255.255.255.0
These 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.

The 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.
7-4
202-10005-05, June 2005
Advanced Configuration
Reference Manual for the Broadband Mobile Router MBR814
— 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.
Note: If you change the LAN IP address of the router while connected through the
browser, you will be disconnected. You must then open a new connection to the new IP
address and log in again.
DHCP
By 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 server
If another device on your network will be the DHCP server, or if you will manually configure the
network settings of all of your computers, clear the ‘Use router as DHCP server’ check box.
Otherwise, leave it 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 address

•
Primary DNS Server, if you entered a Primary DNS address in the Basic Settings menu;
otherwise, the router’s LAN IP address
•
Secondary DNS Server, if you entered a Secondary DNS address in the Basic Settings 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 addresses
When 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 Settings
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 User Name, Password and LAN
address you have chosen for the router.

in Figure 7-3:
Figure 7-3: LAN IP Setup Menu
3. Enter the TCP/IP, DHCP, or Reserved IP parameters.
4. Click Apply to save your changes.
Configuring Dynamic DNS
If 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.

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

10. Click Apply to save your configuration.
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.
Using Static Routes
Static 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 Example
As an example of when a static route is needed, consider the following case:
•
Your primary Internet access is through a cable modem to an ISP.
•
You have an ISDN router on your home network for connecting to the company where
you are employed. This router’s address on your LAN is 192.168.0.100.
•
Your company’s network is 134.177.0.0.
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.

•
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 Routes
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 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 Table
3. To add or edit a Static Route:
a. Click the Edit button to open the Edit Menu, shown in Figure 7-6.

b. 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:

Reference Manual for the Broadband Mobile Router MBR814
2. Fill out the UPnP screen:
•
Turn UPnP On: 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.

c. The WAN port LED is lit.
Troubleshooting
8-1
202-10005-05, June 2005
Reference Manual for the Broadband Mobile Router MBR814
If 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 On
If 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 On
When 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 On
If 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.

Troubleshooting the Web Configuration Interface
If 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.

Troubleshooting the ISP Connection
If your router is unable to access the Internet, you should check the ADSL connection, then the
WAN TCP/IP connection.
ADSL link
If 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 Green
If 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 Off
If 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 Address
If 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:
8-4
Troubleshooting
202-10005-05, June 2005
Reference Manual for the Broadband Mobile Router MBR814
•
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.
OR
Configure 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 Browsing
If your router can obtain an IP address but your computer is unable to load any Web pages from the
Internet:
•
Your computer may not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www addresses)
to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS
servers for your use. If you entered a DNS address during the router’s configuration, reboot
your computer and verify the DNS address as described in “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 Utility
Most 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.

Testing the LAN Path to Your Router
You 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 192.168.0.1
3. Click OK.
You should see a message like this one:
Pinging  with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
If 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 Device
After verifying that the LAN path works correctly, test the path from your PC to a remote device.
From the Windows run menu, type:

where  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 Password
This 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 button
To restore the factory default configuration settings without knowing the administration password
or IP address, you must use the Default Reset button on the rear panel of the router.
1. Press and hold the Default Reset button until the Test LED turns on (about 10 seconds).
2. Release the Default Reset button and wait for the router to reboot.

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. If you have just completed configuring the
router, wait at least five minutes and check the date and time again.

Network and Routing Basics
This chapter provides an overview of IP networks and routing.
Related Publications
As 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 Concepts
Large 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.
Network and Routing Basics
B-1
202-10005-05, June 2005
Reference Manual for the Broadband Mobile Router MBR814
Routing Information Protocol
One 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 Internet
Because 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:
195.34.12.7
The 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.

The 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.
Network and Routing Basics

202-10005-05, June 2005
Reference Manual for the Broadband Mobile Router MBR814
This 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.
Netmask
In 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)
11111111
11111111
00000000 (255.255.255.0)
10101000
10101010
00000000 (192.168.170.0)
combined with:
11111111
Equals:
11000000
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 Addressing
By 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.
B-4
Network and Routing Basics
202-10005-05, June 2005
Reference Manual for the Broadband Mobile Router MBR814
Subnet 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.
Class B
Network
Subnet
Node

Figure B-2: Example of Subnetting a Class B Address
A Class B address can be effectively translated into multiple Class C addresses. For example, the
IP address of 172.16.0.0 is assigned, but node addresses are limited to 255 maximum, allowing
eight extra bits to use as a subnet address. The IP address of 172.16.97.235 would be interpreted as
IP network address 172.16, subnet number 97, and node number 235. In addition to extending
the number of addresses available, subnet addressing provides other benefits. Subnet addressing
allows a network manager to construct an address scheme for the network by using different
subnets for other geographical locations in the network or for other departments in the
organization.
Although the preceding example uses the entire third octet for a subnet address, note that you are
not restricted to octet boundaries in subnetting. To create more network numbers, you need only
shift some bits from the host address to the network address. For instance, to partition a Class C
network number (192.68.135.0) into two, you shift one bit from the host address to the network
address. The new netmask (or subnet mask) is 255.255.255.128. The first subnet has network
number 192.68.135.0 with hosts 192.68.135.1 to 129.68.135.126, and the second subnet has
network number 192.68.135.128 with hosts 192.68.135.129 to 192.68.135.254.
Note: The number 192.68.135.127 is not assigned because it is the broadcast address
of the first subnet. The number 192.68.135.128 is not assigned because it is the network
address of the second subnet.
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.

NETGEAR strongly recommends that you configure all hosts on a LAN segment to use the same
netmask for the following reasons:
•
So that hosts recognize local IP broadcast packets
B-6
Network and Routing Basics
202-10005-05, June 2005
Reference Manual for the Broadband Mobile Router MBR814
When 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 remote
Private IP Addresses
If 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 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
NETGEAR 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 NAT
In 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.

This 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 Protocol
An 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.
B-8
Network and Routing Basics
202-10005-05, June 2005
Reference Manual for the Broadband Mobile Router MBR814
Related Documents
The 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 Server
Many 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 DHCP
When 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.
Network and Routing Basics
B-9
202-10005-05, June 2005
Reference Manual for the Broadband Mobile Router MBR814
The 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 Firewalls
When 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 Inspection
Unlike simple Internet sharing routers, a firewall uses a process called stateful packet inspection to
ensure secure firewall filtering to protect your network from attacks and intrusions. Since
user-level applications such as FTP and Web browsers can create complex patterns of network
traffic, it is necessary for the firewall to analyze groups of network connection states. Using
Stateful Packet Inspection, an incoming packet is intercepted at the network layer and then
analyzed for state-related information associated with all network connections. A central cache
within the firewall keeps track of the state information associated with all network connections.
All traffic passing through the firewall is analyzed against the state of these connections in order to
determine whether or not it will be allowed to pass through or rejected.

Denial of Service Attack
A 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 Cabling
Although 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
Table B-1.

Category 5 Cable Quality
Category 5 distributed cable that meets ANSI/EIA/TIA-568-A building wiring standards can be a
maximum of 328 feet (ft.) or 100 meters (m) in length, divided as follows:
20 ft. (6 m) between the hub and the patch panel (if used)
295 ft. (90 m) from the wiring closet to the wall outlet
Network and Routing Basics

202-10005-05, June 2005
Reference Manual for the Broadband Mobile Router MBR814
10 ft. (3 m) from the wall outlet to the desktop device
The 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 Cables
For 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.

Note: Flat “silver satin” telephone cable may have the same RJ-45 plug. 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 Switching
In 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).
Network and Routing Basics
B-13
202-10005-05, June 2005
Reference Manual for the Broadband Mobile Router MBR814
When 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
This 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).
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.
Preparing Your Computers for TCP/IP Networking
Computers 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.

In 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)—192.168.0.1
These addresses are part of the IETF-designated private address range for use in private networks.
Configuring Windows 95, 98, and Me for TCP/IP Networking
