NAT (Net Address Translation) NAT automatically assigns private IP addresses (10.1.1.x) to
LAN-connected devices.
• Enable. Usually NAT is enabled.
• Disable. This disables NAT, but leaves the firewall active.
Disable NAT only if you are sure that you do not require it.
When NAT is disabled, only standard routing is performed
by this router. Classical routing lets you directly manage the
IP addresses that the modem router uses. Classical routing
should be selected only by experienced users
• Disable firewall. This disables the firewall in addition to
disabling NAT. With the firewall disabled, the protections
usually provided to your network are disabled.
These fields
appear only if no
login is required.
Router MAC Address The Ethernet MAC address that will be used by the modem
router on the Internet port. Some ISPs register the Ethernet
MAC address of the network interface card in your computer
when your account is first opened. They will then accept traffic
only from the MAC address of that computer. This feature
allows your modem router to masquerade as that computer by
“cloning” its MAC address.
• Use Default Address. Use the default MAC address.
• Use Computer MAC Address. The modem router will
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.
• Use This MAC Address. Enter the MAC address that you
want to use.
*. Disabling NAT reboots the modem router and resets its configuration settings to the factory defaults. Disable NAT only if you
plan to install the modem router in a setting where you will be manually administering the IP address space on the LAN side
of the router.

How the Internet Connection Works
Your modem router is now configured to provide Internet access for your network. Your modem
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. The modem router performs these functions automatically as needed.
To access the Internet from any computer connected to your modem router, launch an Internet
browser such as Microsoft Internet Explorer. You should see the modem router’s Internet LED
blink, indicating communication to the ISP. The browser should begin to display a Web page.

Chapter 2
Configuring Your Wireless Network
and Security Settings
This chapter describes how to configure the wireless features of your DG834N RangeMaxTM
NEXT Wireless ADSL2+ Modem Router. For a wireless connection, the SSID, also called the
wireless network name, and the wireless security setting must be the same for the modem router
and wireless computers or wireless adapters. NETGEAR strongly recommends that you use
wireless security.
Warning: Computers can connect wirelessly at a range of several hundred feet. This can
allow others outside of your immediate area to access your network.
This chapter includes:
• “Planning Your Wireless Network” on this page
• “Configuring Your Wireless Network” on page 2-4
• “Configuring Your Wireless Security” on page 2-10
Planning Your Wireless Network
For compliance and compatibility between similar products in your area, the operating channel
and region must be set correctly.
To manually configure the wireless settings, you must know the following:
• SSID. The default SSID for the modem router is NETGEAR.
• The wireless mode (802.11n, 802.11g, or 802.11b) that each wireless adapter supports.
• Wireless security option. To successfully implement wireless security, check each wireless
adapter to determine which wireless security option it supports.

Wireless Placement and Range Guidelines
The range of your wireless connection can vary significantly based on the physical placement of
the modem router. The latency, data throughput performance, and notebook power consumption of
wireless adapters also vary depending on your configuration choices.
For best results, place your modem router according to the following guidelines:
• Near the center of the area in which your PCs will operate.
• In an elevated location such as a high shelf where the wirelessly connected PCs have
line-of-sight access (even if through walls).
• Away from sources of interference, such as PCs, microwave ovens, and 2.4 GHz cordless
phones.
• Away from large metal surfaces.
• Put the antenna in a vertical position to provide the best side-to-side coverage. Put the antenna
in a horizontal position to provide the best up-and-down coverage.
• If using multiple access points, it is better if adjacent access points use different radio
frequency channels to reduce interference. The recommended channel spacing between
adjacent access points is 5 channels (for example, use Channels 1 and 6, or 6 and 11).
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.
Wireless Security Options
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 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 modem router provides highly effective security features, which are
covered in detail in this chapter. Deploy the security features appropriate to your needs

There are several ways you can enhance the security of your wireless network:
Figure 2-1
• Restrict access based on MAC address. You can allow only trusted PCs to connect so that
unknown PCs cannot wirelessly connect to the modem router. 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 (see “Restricting access by MAC address” on page 2-11).
• 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 (see
“Hiding your wireless network name (SSID)” on page 2-11).
• WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared
Key authentication and WEP data encryption block all but the most determined eavesdropper.
This data encryption mode has been superseded by WPA-PSK and WPA2-PSK (see
“Configuring WEP” on page 2-14).
• WPA-802.1x. Wi-Fi Protected Access (WPA) with user authentication implemented using
IEE 802.1x and RADIUS servers (see “Configuring WPA-802.1x” on page 2-16).
• WPA-PSK (TKIP) + WPA2-PSK (AES). Wi-Fi Protected Access (WPA) using a pre-shared
key to perform authentication and generate the initial data encryption keys. The very strong
authentication along with dynamic per frame re-keying of WPA makes it virtually impossible
to compromise (see “Configuring Mixed WPA-PSK+WPA2-PSK Security” on page 2-13).

Restricting Wireless Access to Your Network
By default, any wireless PC that is configured with the correct SSID can access your wireless
network. For increased security, the modem router provides several ways to restrict wireless access
to your network. You can do the following:
• Turn off wireless connectivity completely.
• Restrict access based on the wireless network name (SSID).
• Restrict access based on the Wireless Card Access List.
2-10 Configuring Your Wireless Network and Security Settings
v1.0, October 2008
Page 35
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
These options are discussed in the following sections.
Turning off wireless connectivity completely
You can completely turn off the wireless portion of the modem router. For example, if you use
your notebook computer to wirelessly connect to your modem router and you take a business trip,
you can turn off the wireless portion of the modem router while you are traveling. Other members
of your household who use computers connected to the modem router through Ethernet cables can
still use the modem router. To do this, clear the Enable Wireless Access Point check box on the
Wireless Settings screen, and then click Apply.
Hiding your wireless network name (SSID)
By default, the modem router is set to broadcast its wireless network name (SSID). You can
restrict wireless access to your network by not broadcasting the wireless network name (SSID). To
do this, clear the Allow Broadcast of ame (SSID) check box on the Wireless Settings screen,
and then click Apply. Wireless devices will not “see” your modem router. You must configure
your wireless devices to match the wireless network name (SSID) of the modem router.
Warning: The SSID of any wireless access adapters must match the SSID you specify in
the modem router. If they do not match, you will not get a wireless connection
to the modem router.
Restricting access by MAC address
For increased security, you can restrict access to the wireless network to allow only specific PCs
based on their MAC addresses. You can restrict access to only trusted PCs so that unknown PCs
cannot wirelessly connect to the Amodem router. MAC address filtering adds an obstacle against
unwanted access to your network, but the data broadcast over the wireless link is fully
exposed.The Wireless Station Access list determines which wireless hardware devices will be
allowed to connect to the modem router.

each wireless computer to obtain a wireless link to the modem router. The
computer should then appear in the Attached Devices screen.
ote: If you are configuring the modem 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 modem router from a wired computer to
make any further changes.
6. Make sure the Turn Access Control On check box is selected, and then click Apply.
Now, only devices on this list will be allowed to wirelessly connect to the modem router. This
prevents unauthorized access to your network.
Configuring Mixed WPA-PSK+WPA2-PSK Security
A high-performance client such as the NETGEAR WN511B must connect to the modem router
using WPA2-PSK to achieve maximum performance. Wireless clients that connect to the modem
router using WPA-PSK run at no more than 802.11g speed. This option allows wireless clients to
use either encryption method.
ote: Not all wireless adapters support WPA or WPA2. Furthermore, client software is
required on the client. Windows XP and Windows 2000 with Service Pack 3 do
include the client software that supports WPA. Nevertheless, the wireless adapter
hardware and driver must also support WPA. Consult the product document for
your wireless adapter and WPA client software for instructions on configuring
WPA settings.

For details about WPA-802.1x authentication options, see “Configuring WPA-802.1x” on
page 2-16.
Choosing Alternative Authentication and Encryption Methods
Restricting wireless access prevents intruders from connecting to your network. However, the
wireless data transmissions are still vulnerable to snooping. Using the data encryption settings
described in this section 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.
Configuring WEP
Wired Equivalent Privacy (WEP) security is the most basic and simplest form of wireless security.
It is the most often used, but least secure of the available options. WEP Shared Key authentication
and WEP data encryption block all but the most determined eavesdropper. This data encryption
mode has been superseded by WPA-PSK and WPA2-PSK.

Protecting Access to Your Wireless Modem Router
For security reasons, the modem router has its own user name and password. Also, after a period
of inactivity for a set length of time, the administrator login automatically disconnects. When
prompted, enter admin for the modem router user name and password for the modem router
password. You can use the following procedures to change the modem router’s password and the
period for the administrator’s login time-out.
ote: The user name and password are not the same as any other user name or password
your might 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 case and lower case letters, numbers, and symbols. Your password can be up to 30
characters.

Configuring Basic Firewall Services
Basic firewall services that you can configure include access blocking and scheduling of firewall
security. These topics are presented in the following sections.
Blocking Keywords, Sites, and Services
The modem router provides a variety of options for blocking Internet-based content and
communications services. With its content filtering feature, the RangeMax NEXT Wireless
ADSL2+ Modem Router prevents objectionable content from reaching your PCs. The modem
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 following section explains how to configure your modem router to perform these functions.
How to Block Keywords and Sites
The modem 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 modem router 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 password and LAN
address you might have previously set for the modem router.

• Always. Turn on keyword blocking all the time, independent of the Schedule screen.
4. Enter a keyword or domain in the Type Keyword or Domain ame Here field, and then
click Add Keyword.
Keyword application examples:
• If the keyword XXX is specified, the URL www.zzzyyqq.com/xxx.html is blocked.
• If the keyword .com is specified, only websites with other domain suffixes (such as .edu,
.org, or .gov) can be viewed.
• If a period (.) is specified as the keyword, all Internet browsing access is blocked.

Containing these Keywords or Domain Names:” list). To delete a keyword or
domain, select it from the list, click Delete Keyword. To delete all keywords,
click Clear List.
5. You can specify one trusted user, which is a computer that will be exempt from blocking and
logging. Since the trusted user will be identified by an IP address, you should configure that
computer with a fixed IP address.
To allow a trusted user to visit blocked sites:
a. Select the Allow Trusted IP Address to Visit Blocked Sites check box.
b. Enter the computer’s IP address in the Trusted IP Address field.
6. Click Apply to save your settings.
Firewall Rules
Firewall rules 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 modem router 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 takes effect
first. See “Order of Precedence for Rules” on page 3-12 for more details.
To access the rules configuration of the modem router, select Firewall Rules on the main menu.
The Firewall Rules screen displays

Figure 3-4
To configure firewall rules:
• To add either an outbound or inbound service, click Add. For more information, see “Inbound
Rules (Port Forwarding)—the following section—and “Outbound Rules (Service Blocking)”
on page 3-9.
• 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 prompt, enter the number of the desired new position and
click OK.
Inbound Rules (Port Forwarding)
Because the modem router 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 modem 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.

ote: 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 might
periodically check for servers and might 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. Enable only those ports
that are necessary for your network. Following are two application examples of inbound rules.
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. An inbound rule is shown in the Inbound Services screen, which is accessible by clicking on
Add under Inbound Services in the Firewall Rules screen.

– BLOCK by schedule, otherwise Allow. Traffic for the selected service is blocked
according to how the service is defined in the Services screen, but otherwise allowed.
• Send to LA Server. Enter the IP address of the computer or server on your LAN that will
receive the inbound traffic covered by this rule.
• WA Users. These settings determine which packets are covered by the rule, based on their
source (WAN) IP address. Select the option that you want:
– Any. All IP addresses are covered by this rule.
– Single address. Enter the required start address in the Start field.
– Address range. If this option is selected, you must enter the start and finish addresses in
the Start and Finish fields.
• Log. You can select whether the traffic will be logged. The choices are:
– ever. No log entries will be made for this service.
– Always. Any traffic for this service type will be logged.
– Match. Traffic of this type that matches the settings and action will be logged.
– ot match. Traffic of this type that does not match the settings and action will be logged.
Inbound Rule Example: Allowing Video conferencing
If you want to allow incoming video conferencing 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 the following figure, 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 settings.

Figure 3-6
Considerations for Inbound Rules
• If your external IP address is assigned dynamically by your ISP, the IP address might change
periodically as the DHCP lease expires. Consider using the Dynamic DNS screen so that
external users can always find your network.
• If the IP address of the local server computer is assigned by DHCP, it might change when the
computer is rebooted. To avoid this, use the Reserved IP address feature in the LAN IP Setup
screen 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 the previous figure). Attempts by local computers to access
the server using the external WAN IP address will fail.
Outbound Rules (Service Blocking)
The modem router 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 the following:
• IP address of the local computer (source address)
• IP address of the Internet site being contacted (destination address)
• Time of day
Protecting Your Network 3-9
v1.0, October 2008
Page 50
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
• 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 create in the Schedule screen.You can specify that the modem
router logs any attempt to use Instant Messenger during this blocked period. You can also open or
close Instant Messenger ports: see the Firewall Rules screen in the “Order of Precedence for
Rules” section on page 3-12.
An outbound rule is shown in the Outbound Services screen, which is accessible by clicking on
Add under Outbound Services in the Firewall Rules screen.

Order of Precedence for Rules
As you define new rules, they are added to the tables in the Firewall Rules screen, as shown in the
following figure:
Figure 3-8
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 might 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.
The Firewall Rules screen also lets you easily open or close AOL or MSN Instant Messenger
ports:

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 modem router already holds a list of many service port numbers, you are not limited
to these choices. Use the following procedure to create your own service definitions.
How to Define Services
1. Log in to the modem router 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 password and
LAN address you have chosen for the modem router.

Chapter 5
Advanced Configuration
This chapter describes how to configure the advanced features of your DG834N RangeMaxTM
NEXT Wireless ADSL2+ Modem Router.
Configuring Advanced Security
The modem router provides a variety of advanced features, which are described in the following
sections:
• “Setting Up a Default DMZ Server” on this page
• “Connecting Automatically, as Required” on page 5-3
• “Disabling Port Scan and DOS Protection” on page 5-3
• “Responding to a Ping on an Internet WAN Port” on page 5-3
• “Setting the MTU Size” on page 5-3
• “Disabling the SIP ALG” on page 5-3
• “Configuring LAN IP Settings” on page 5-4
• “Configuring DHCP” on page 5-6
• “Configuring LAN TCP/IP Settings” on page 5-7
• “Configuring Dynamic DNS” on page 5-8
• “Using Static Routes” on page 5-10
• “How to Configure Universal Plug and Play” on page 5-13
• “Building Wireless Bridging and Repeating Networks” on page 5-14
These features are discussed in the following sections.
Setting Up a Default DMZ Server
The default demilitarized zone (DMZ) server feature is helpful when you use some online games
and videoconferencing applications that are incompatible with NAT. The modem router is
programmed to recognize some of these applications and to work correctly with them, but there
are other applications that might not function well. In some cases, one local computer can run the
application correctly if that computer’s IP address is entered as the default DMZ server.
5-1
v1.0, October 2008
Page 78
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
ote: 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 usually discarded by the modem router unless the traffic is a
response to one of your local computers or a service that you have configured in the Ports screen.
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:
1. Log in to the modem router 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 user name,
password, and LAN address you have chosen for the modem router.
2. In the main menu, under Advanced, click WA Setup to display the following screen.

DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
4. Type the IP address for that server.
5. Click Apply to save your changes.
Other WAN Options
The WAN Setup screen that is shown in Figure 5-1 also allows you perform the following tasks:
• Connecting Automatically, as Required
Usually, this option should be enabled, so that an Internet connection is made automatically,
whenever Internet-bound traffic is detected. If this causes high connection costs, you can
disable this setting.
If this setting is disabled, you must connect manually, using the screen that you access by
clicking the Connection Status button on the Status screen.
If you have an Always on connection, this setting has no effect.
• Disabling Port Scan and DOS Protection
The firewall protects your LAN against port scans and denial of service (DOS) attacks. This
protection should be disabled only in special circumstances.
• Responding to a Ping on an Internet WA Port
If you want the modem router to respond to a ping from the Internet, select the Respond to
Ping on Internet WA Port check box. This should be used only as a diagnostic tool, since it
allows your modem router to be discovered. Do not select this check box unless you have a
specific reason to do so.
• Setting the 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 might 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.
• Disabling the SIP ALG
The Session Initiation Protocol (SIP) Application Level Gateway (ALG) is enabled by default
to optimize VoIP phone calls that use the SIP. The Disable SIP ALG check box allows you to
disable the SIP ALG. Disabling the SIP ALG might be useful when running certain
applications.

DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Configuring LAN IP Settings
The LAN IP Setup screen allows configuration of LAN IP services such as DHCP and RIP.
The modem router is shipped preconfigured to use private IP addresses on the LAN side, and to act
as a DHCP server. The modem router’s default LAN IP configuration is as follows:
• LAN IP address. 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 by opening the
LAN IP Setup menu.
Under Advanced in the main menu, select LA IP Setup.
Figure 5-2
5-4 Advanced Configuration
v1.0, October 2008
Page 81
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
The LAN TCP/IP Setup settings are:
• IP Address. This is the LAN IP address of the modem router.
• IP Subnet Mask. This is the LAN subnet mask of the modem 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 modem router.
• RIP Direction. Router Information Protocol (RIP) allows a modem router to exchange routing
information with other routers. The RIP Direction selection controls how the modem router
sends and receives RIP packets. Both is the default setting.
– When set to Both or Out Only, the modem router broadcasts its routing table periodically.
– When set to Both or In Only, the modem router incorporates the RIP information that it
receives.
– When set to one, the modem router does not send any RIP packets and ignores any RIP
packets received.
• RIP Version. This controls the format and the broadcasting method of the RIP packets that the
modem router sends. It recognizes both formats when receiving. By default, this is set for
RIP-1.
– RIP-1. This version is universally supported. RIP-1 is probably adequate for most
networks, unless you have an unusual network setup.
– RIP-2. This version carries more information. Both RIP-2B and RIP-2M send the routing
data in RIP-2 format.
• RIP-2B. This version uses subnet broadcasting.
• RIP-2M. This version uses multicasting.
• Access Router Management Interface on additional port. When NAT is disabled, the
modem router’s management interface may be accessed at the modem router’s LAN address
using the port number you enter. This feature is not available when NAT is enabled.
ote: If you change the LAN IP address of the modem 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.
Advanced Configuration 5-5
v1.0, October 2008
Page 82
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Configuring DHCP
By default, the modem router functions as a Dynamic Host Configuration Protocol (DHCP) server,
allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to
the modem router’s LAN. The assigned default gateway address is the LAN address of the router.
IP addresses are assigned to the attached PCs from a pool of addresses specified in this screen.
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 the
online document that you can access from “TCP/IP Networking Basics” in Appendix A 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 might want to save part of the range for devices with fixed addresses.
The router delivers the following settings 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 screen;
otherwise, the router’s LAN IP address
• Secondary DNS server, if you entered a secondary DNS address in the Basic Settings screen
• WINS server, short for Windows Internet aming 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.

DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
How to Configure Reserved IP Addresses
When you specify a reserved IP address for a computer on the LAN, that computer will always
receives 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. In the LAN IP Setup screen, click the Add button.
2. In the IP Address field, 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 screen and paste it here.
4. Click Apply to enter the reserved address into the table.
ote: 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 that you want to edit or delete.
2. Click Edit or Delete.
Configuring 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 and default password of password, or using whatever user name, password, and
LAN address you have chosen for the router.

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.
5-8 Advanced Configuration
v1.0, October 2008
Page 85
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
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 automatically contacts your Dynamic DNS service provider, logs in to your
account, and registers your new IP address.
How to Configure Dynamic DNS
1. Log in to the modem router 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 user name,
password, and LAN address you have chosen for the modem router.
2. In the main menu, under Advanced, select Dynamic DS to display the following screen.
Figure 5-4
3. Access the website of one of the Dynamic DNS service providers whose names appear in the
Service Provider drop-down list, and register for an account. For example, for dyndns.org, go
to www.dyndns.org.
4. Select the Use a dynamic DS 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 might 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.
Advanced Configuration 5-9
v1.0, October 2008
Page 86
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
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
causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org.
10. Click Apply to save your configuration.
ote: 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 address 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 modem 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 forwards your request to the ISP. The ISP forwards your
request to the company where you are employed, and the request is likely to 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 setup would look like Figure 5-6.
In this example:
5-10 Advanced Configuration
v1.0, October 2008
Page 87
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
• The Destination IP Address and IP Subnet Mask fields specify that this static route applies
to all 134.177.x.x addresses.
• The Gateway IP Address field specifies that all traffic for these addresses should be
forwarded to the ISDN router at 192.168.0.100.
• The value in the Metric field represents the number of routers between your network and the
destination. This is a direct connection, so it can be set to the minimum value of 2.
• The Private check box is selected only as a precautionary security measure in case RIP is
activated.
How to Configure Static Routes
1. Log in to the modem router 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 user name,
password, and LAN address you have chosen for the modem router.
2. In the main menu, under Advanced, select Static Routes to display the Static Routes table.
Figure 5-5
Advanced Configuration 5-11
v1.0, October 2008

DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
3. To add a static route:
a. Click Add to open the following Static Routes screen.
Figure 5-6
b. Enter a route name for this static route in the Route ame field. This name 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. Enter the destination IP address of the final destination.
f. Enter the IP subnet mask for this destination. If the destination is a single host, type
255.255.255.255.
g. Enter the gateway IP address, which must be a router on the same LAN segment as the
router.
h. Enter a number between 2 and 15 as the metric value in the Metric field. This represents
the number of routers between your network and the destination. Usually, a setting of 2 or
3 works.

How to Configure Universal Plug and Play
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. Select UPnP on the main menu to display the UPnP screen:
Figure 5-8
Advanced Configuration 5-13
v1.0, October 2008
Page 90
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
2. Fill in the settings on the UPnP screen:
• Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration. The
default setting for UPnP is enabled. If UPnp is disabled, the modem router does not allow
any device to automatically control the resources, such as port forwarding (mapping), of
the modem router.
• Advertisement Period. The advertisement period is how often the modem router
advertises (broadcasts) its UPnP information. This value can range from 1 to 1440
minutes. The default period is 30 minutes. Shorter durations ensure that control points
have current device status at the expense of additional network traffic. Longer durations
might 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 might 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 modem 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 your changes, or refresh the table:
• Click Apply to save the new settings to the modem router.
• Click Cancel to disregard any unsaved changes.
• Click Refresh to update the portmap table and to show the active ports that are currently
opened by UPnP devices.
Building Wireless Bridging and Repeating Networks
With the DG834N modem router, you can build large bridged wireless networks using Wireless
Distribution System (WDS). Using the modem router with other access points (APs) and wireless
devices, you can connect clients by using their MAC addresses rather than by specifying IP
addresses. All APs in the system must support WDS.
5-14 Advanced Configuration
v1.0, October 2008
Page 91
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Here are some examples of wireless bridged configurations:
• Point-to-point bridge. The modem router communicates with another bridge-mode wireless
station. See “How to Configure a Point-to-Point Bridge Configuration.”
• Multi-point bridge. The modem router is the “master” for a group of bridge-mode wireless
stations. Then all traffic is sent to this master, rather than to other access points. See “How to
Configure a Multi-Point Bridge.”
• Repeater with wireless client association. Sends all traffic to the remote access point. See
“How to Configure a Repeater with Wireless Client Association.”
ote: The wireless bridging and repeating feature uses the default security profile to send
and receive traffic.
To view or change these configurations, select Advanced Wireless Settings from the main menu:

How to Configure a Point-to-Point Bridge Configuration
In point-to-point bridge mode, the DG834N modem router communicates as an access point with
another bridge-mode wireless station. As a bridge, wireless client associations are disabled—only
wired clients can be connected. You must enter the MAC address of the other bridge-mode
wireless station in the field provided. Use wireless security to protect this communication.
The following figure shows an example of point-to-point bridge mode.
Figure 5-10
To set up a point-to-point bridge configuration (shown in Figure 5-10):
1. Configure the DG834N modem router (AP 1) on LAN Segment 1 in point-to-point bridge
mode.
2. Configure the other access point (AP 2) on LAN Segment 2 in point-to-point bridge mode.
The DG834N modem router must have AP 2’s MAC address in its Remote MAC Address
field, and AP 2 must have the DG834N’s MAC address in its Remote MAC Address field.
3. Configure both APs and verify that both APs are using he same SSID, channel, authentication
mode, if any, and security settings if security is in use.
4. Disable the DHCP server on AP2. AP1 will then be the DHCP server.
5. Verify connectivity across LAN Segment 1 and LAN Segment 2.

How to Configure a Multi-Point Bridge
Multi-point bridge mode allows a modem router to bridge to multiple peer access points
simultaneously. As a bridge, wireless client associations are disabled—only wired clients can be
connected. Multi-point bridge mode configuration includes the following steps:
• Entering the MAC addresses of the other access points in the fields provided.
• Setting the other bridge-mode access points to Point-to-Point Bridge mode, using the MAC
address of this DG834N as the Remote MAC Address.
• Using wireless security to protect this traffic.
The following figure shows an example of a multi-point bridge mode configuration.
Figure 5-11
Advanced Configuration 5-17
v1.0, October 2008

DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
To set up the multi-point bridge configuration shown in Figure 5-11:
1. Configure the operating mode of the modem routers.
• Because it is in a central location, configure the DG834N modem router (AP 1) on LAN
Segment 1 in point-to-multi-point bridge mode, and enter the MAC addresses of
AP-2 and AP-3 in the Remote MAC Address 1 and Remote MAC Address 2 fields.
• Configure the access point (AP2) on LAN Segment 2 in point-to-point bridge mode with
the remote MAC address of the DG834N modem router.
• Configure the access point (AP3) on LAN Segment 3 in point-to-point bridge mode with
the remote MAC address of the DG834N modem router.
2. Disable the DHCP server on AP2 and AP3. AP1 will then be the DHCP server.
3. Verify the following for all access points:
• The LAN network configuration of the modem router and other access points are
configured to operate in the same LAN network address range as the LAN devices.
• Only one AP, the DG834N modem router in Figure 5-11, is configured in point-to-multi-
point bridge mode; all the others are in point-to-point bridge mode.
• All APs, including the DG834N modem router, must be on the same LAN. That is, all the
AP LAN IP addresses must be in the same network.
• If you are using DHCP, all access points should be set to Obtain an IP address
automatically (DHCP Client) in the IP Address Source section of the Basic IP Settings
screen.
• All APs, including the DG834N modem router, must use the same SSID, channel,
authentication mode, if any, and security settings if security is in use.
• All point-to-point APs must have the MAC address of AP 1 (the DG834N modem router
in the previous figure) in the Remote AP MAC address field.
4. Verify connectivity across the LANs.
• A computer on any LAN segment should be able to connect to the Internet or share files
and printers with any other PCs or servers connected to any of the three LAN segments.
ote: Wireless stations configured as they are in Figure 5-11 will not be able to connect
to the modem router or access points. If you require wireless stations to access any
LAN segment, you can use additional access points configured in wireless access
point mode in any LAN segment.

How to Configure a Repeater with Wireless Client Association
In the repeater mode with wireless client association, the DG834N modem router sends all traffic
to a remote AP. For the repeater mode, you must enter the MAC address of the remote “parent”
access point. Alternatively, you can configure the DG834N modem router as the parent by entering
the address of a “child” access point. Note that the following restrictions apply:
• You do not have the option of disabling client associations with this DG834N modem router.
• You cannot configure a sequence of parent/child APs. You are limited to only one parent AP,
although if the DG834N modem router is the parent AP, it can connect with up to four child
APs.
The following figure shows an example of a Repeater mode configuration.
Figure 5-12
To set up a repeater with wireless client association:
1. Configure the operating mode of the devices.
• Configure AP 1 (the DG834N modem router in Figure 5-12) on with the MAC address of
AP 2 and AP 3 in the first two Remote MAC Address fields.
• Configure AP 2 with the MAC address of AP 1 in the Remote MAC Address field.
• Configure AP 3 with the MAC address of AP 1 in the Remote MAC Address field.

2. Verify the following for both access points:
• The LAN network configuration of each AP is configured to operate in the same LAN
network address range as the LAN devices.
• The APs must be on the same LAN. That is, the LAN IP addresses for the APs must be in
the same network.
• If you are using DHCP, AP devices should be set to Obtain an IP address automatically
(DHCP Client) in the IP Address Source section of the Basic IP Settings screen.
• AP devices must use the same SSID, channel, authentication mode, and encryption.
3. Verify connectivity across the LANs. A computer on any LAN segment should be able to
connect to the Internet or share files and printers with any other PCs or servers connected to
any of the three WLAN segments.

Go to “Restoring the Default Configuration and Password” on page 6-10.
• I want to clear the configuration and start over again.
Go to “Restoring the Default Configuration and Password” on page 6-10.
Basic Functioning
After you turn on power to the router, the following sequence of events should occur:
1. When power is first applied, verify that the Power LED is on.
2. After approximately 10 seconds, verify the following:
a. The LAN port LEDs are lit for any local ports that are connected.
b. The ADSL Link LED is lit.
v1.0, October 2008
6-1
Page 98
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
If the ADSL link 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 is amber.
If any of these conditions do not occur, refer to the appropriate following section.
“Welcome” Page Displays instead of Router Management
Interface
This situation can occur if the CD Setup Wizard does not complete successfully; the unit will stay
in “Wizard Mode”. If the “Welcome” page displays instead of the Router Management interface
when you try to go to the Internet or log into the Router Management interface, you can bypass the
wizard using one of the following methods:
• Log into the Router Management interface at http://routerlogin.com/basicsetting.htm.
• Perform a factory reset to take the router out of “Wizard Mode” altogether.
Power LED Is 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.
Power LED Is Red
When the router is turned on, it performs a power-on self-test. If the Power LED turns red after a
few seconds or at any other time during normal operation, there is a fault within the router. The
Power LED also turns red when you press the default reset button, and blinks red 3 times when
you release that button. However, in this case, the modem router is working normally.
If the Power LED turns red to indicate a router fault, turn the power off and on to see if the router
recovers.
If the power LED is still red 1 minute after power up:
• Turn the power off and on to see if the router recovers.
• Clear the router’s configuration to factory defaults. This sets the router’s IP address to
192.168.0.1. This procedure is explained in “Using the Reset Button” on page 6-10.

DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
If the error persists, you might have a hardware problem and should contact Technical Support.
LAN or ADSL Link LED Is Not On
If either the LAN LEDs or ADSL Link LED does not light when the Ethernet connection is made,
check the following:
• Make sure that the Ethernet cable connections are secure at the router and at the hub or
workstation.
• Make sure that power is turned on to the connected hub or workstation.
• Be sure you are using the correct cable: when connecting the ADSL port, use the cable that
was supplied with the wireless-N modem router. If the ADSL link LED is still off, this may
mean that there is no ADSL service or the cable connected to the ADSL port is bad.
Window Appears Asking You to Reload Firmware
If a window appears with a message asking you to reload the firmware, this indicates that a
problem has been detected with the current firmware. Please follow the on-screen instructions to
access new firmware and reload the firmware into your router.
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 that 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. Follow the instructions in the online document that you can
access from “Preparing Your Network” in Appendix A for information about how to configure
your computer.
• 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.
Troubleshooting 6-3
v1.0, October 2008
Page 100
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
• 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 sets the router’s IP address to 192.168.0.1. This
procedure is explained in “Using the Reset Button” on page 6-10.
• Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click Refresh to be sure that 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 you enter 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 screen or tab, or your changes are lost.
• Click the Refresh or Reload button in the Web browser. The changes might have occurred,
but the Web browser might 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 Internet
LED.
ADSL Link LED Is Green or Blinking Green
If your ADSL link LED is green or blinking green, then you have a good ADSL connection.You
can be confident that the service provider has connected your line correctly and that your wiring is
correct.
ADSL Link LED Is Blinking Amber
If your ADSL link LED is blinking amber, then your modem router is attempting to make an
ADSL connection with the service provider. The LED should turn green within several minutes.
