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.

Security and Firewall Protection
This chapter describes how to use the basic firewall features of the ADSL2+ Modem Router
DM111PSPv2 to protect your network.
This chapter includes:
• “Firewall Settings” in the following section
• “Configuring a DMZ Host” on page 3-10
• “Enabling Universal Plug and Play (UPnP)” on page 3-11
Firewall Settings
You can set up the modem router to use IP packet filtering firewall rules and to use the advanced
features, port forwarding and port triggering. Port forwarding directs inbound traffic for a service
to a local server at a destination port. Port triggering is an advanced feature used for gaming and
other Internet services.
The following are considerations for inbound firewall and port forwarding 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 (such as
192.168.0.11). Attempts by local computers to access the server using the external WAN IP
address will fail.
Security and Firewall Protection 3-1
v1.0, December 2008
ADSL2+ Modem Router DM111PSPv2 User Manual
Before starting, you need to determine which type of protocol, service, application, or gam e you
will provide, and the IP address of the computer that will provide the service. Be sure that the
computer’s IP address never changes.
Note: To assure that the same computer always has the same IP address, use the reserved
IP address feature. See
“Reserved IP Addresses” on page 4-4.
Firewall Rules (IP Filtering)
Firewall rules block or allow specific traffic (IP packets) 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.
Warning: This feature is for advanced users only. Incorrect configuration may cause
serious Internet access problems.
The default inbound and outbound 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 protocol, source IP addresses, and destination IP
addresses.

Port Forwarding (Inbound Rules)
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 inboun d rule you can make a local server (for example, a Web
server or game server) visible and available to the Internet.
The inbound rule that you create 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.

Port Triggering (Outbound Rules)
Port Triggering monitors outboun d traf fic. Wh en the modem router detects traf fic on the specified
outbound port, it remembers the IP address of the computer that sent the data and triggers the
incoming port. Port Trigg ering opens an incoming port temporarily and does not require the server
on the Internet to track your IP address if it is changed by DHCP, for example. Incoming traffic on
the triggered port is then forwarded to the triggering computer. Using the Port Triggering screen,
you can make local computers or servers available to the Internet for different services (for
example, FTP or HTTP), to play Internet games, or to use Internet applications.

2. Check the LAN IP address of your router, which is usually printed on a label on the bottom or
at the rear of the device.
Note how the address is comprised of four numbers separated by period characters. If
necessary, change the LAN IP address of the modem router so that the two left-most numbers
of the address are the same as the two left-most numbers of the router’s LAN IP address, and
the third number in the modem router’s address is different from the third number in the
router’s address. For example, if the router’s LAN IP address is the same as the modem

DHCP Server
Configuration
DHCP Server On The modem router is set up by default to be a DHCP server,
which provides TCP/IP configuration for computers that are
connected to it. You can either use the default settings or 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. You can specify to following settings:
• Start IP. The first of the contiguous addresses in the IP address
pool. 192.168.0.2 is the default start address.
• End IP. The last of the contiguous addresses in the IP address
pool. 192.168.0.254 is the default ending address.
• Lease Time. The period that the DHCP server grants to the
DHCP clients to use the assigned IP addresses.
If you are connecting the modem router to a network with a
router that is the DHCP server, clear the DHCP Server On check
box.

1. Click the button next to the reserved address that you want to delete.
2. Click Delete.
Static Routes
Static routes provide additional routing information to your modem router. Under normal
circumstances, the modem 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.
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 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.

IGMP Proxy
The Internet Group Management Protocol (IGMP) is an Internet protocol that provides a way for
an Internet computer to report its multicast group membership to adjacent routers. The hosts
interact with the system through the exchange of IGMP messages. When you configure IGMP
proxy, the router interacts with other routers through the exchange of IGMP messages. However,
when acting as the proxy, the router performs the host portion of the IGMP task as follows:
• When queried, the router sends membership reports to the group.
• When one of the hosts joins a multicast address group that none of other hosts belongs to, the
router sends unsolicited membership reports to that group.
• When the last host in a particular multicast group leaves the group, the router sends a leave
group membership report to that router’s group.

IP address will be, and the address can change frequently. In this case, you can use a commercial
dynamic DNS service to register your domain to their IP address, and forward traffic directed at
your domain to your frequently changing IP address.
The modem 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 modem router, whenever your ISP-assigned IP address
changes, your modem router will automatically contact your Dynamic DNS service provider, log
in to your account, and register your new IP address.

ADSL LED Situation Action
The ADSL LED is off
(no ADSL link is detected)
The modem router was just
installed and the LED has never
been solid on.
• Make sure that the telephone jack is live—temporarily connect a
standard telephone to the telephone jack to check for a dial tone.
• Make sure that the telephone cable connections are secure at the
modem router and at the ADSL-capable telephone jack.
• Disconnect all telephones on the line. If this solves the problem,
reconnect the telephones one at a time, being careful to use a
microfilter on each telephone. If the microfilters are connected
correctly, you should be able to connect all your telephones.
• If disconnecting telephones does not result in a green Internet LED,
there may be a problem with your wiring. If the telephone company
has tested the ADSL signal at your Network Interface Device (NID),
then you may have poor quality wiring in your house.
• Verify that you are connected to the correct telephone line. If you
have more than one phone line, be sure that you are connected to
the line with the ADSL service. It may be necessary to use a swapper
if you ADSL signal is on pins 1 and 4 or the RJ-11 jack. The ADSL2+
Modem Router uses pins 2 and 3.
• Log in to the modem router as described in “Logging In to the Modem
Router” on page 1-2, and select ADSL Settings from the main menu.
Make sure that your login name and account password are correct
and the ADSL settings are set to the values required by your ISP.

• Check the Ethernet connection between the modem router and the computer or router as
described in the previous section.
• If your computer is directly connected to the modem router, make sure your computer’s IP
address is on the same subnet as the modem 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.
6-4 Troubleshooting
v1.0, December 2008
ADSL2+ Modem Router DM111PSPv2 User Manual
Follow the instructions in the online document that you can access from “Preparing Your
Network” in Appendix B 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 modem router and reboot your
computer.
• If your modem router is connected to your computer via a router , make sure the computer’s IP
address is on the same subnet as the router, and the router is on a different subnet from the
modem router. The LAN IP addresses of the modem router and router will normally be printed
on a label on the bottom or rear of the unit. For details about changing the modem router’s IP
address, see
“LAN IP Setup” on page 4-1.
• If your modem 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 mo dem router’s IP address
to 192.168.0.1. This procedure is explained in
“Using the Reset Button” on page 6-8.
• Make sure that 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 modem router does not save changes you have made in the Web Management 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.

Modem Router Does Not Save Configuration Changes
If the modem router does not save changes you have made, check the following:
• When entering configuration settings, be sure to click the Apply button before moving to
another screen, 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 Internet Connection
If your computer is connected to your modem router via a router , disconnect the router and directly
connect the computer to the modem router. If you now have Internet access, use the documentation
that came with the router to perform re-installation and troubleshooting.
If your modem router is unable to access the internet, but your Internet LED is green or blinking
green, you should determine whether the modem router is able to obtain an IP address from the
ISP. Unless you have been assigned a static IP address, your modem 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 management interface of the modem router using your browser. For details, see
“Logging In to the Modem Router” on page 1-2.
3. Under the Maintenance heading select Modem Status . Check that an IP address is shown for
the ADSL port. If 0.0.0.0 is shown, your modem router has not obtained an IP address from
your ISP.
If your modem router is unable to obtain an IP address from the ISP, check the following:
• Your ISP may require a multiplexing method or Virtual Path Identifier/Virtual Channel
Identifier parameter.
Verify with your ISP the multiplexing method and parameter value, and update the modem
router’s ADSL settings accordingly.
• If your ISP requires PPP over Ethernet (PPPoE) or PPP over ATM (PPPoA), check that your
login credentials are correct.

v1.0, December 2008
ADSL2+ Modem Router DM111PSPv2 User Manual
• Log in to the modem router as described in “Logging In to the Modem Router” on page 1-2,
note the modem router status, run the diagnostics test as described in “Diagnostic Utilities and
Rebooting the Modem Router” on page 2-11, and contact your ISP’s technical support
representative.
Troubleshooting PPPoE or PPPoA Connection
The PPPoA or PPPoA connection can be debugged as follows:
1. Access the Main Menu of the router at http://192.168.0.1.
2. Under the Maintenance heading, select the Diagnostics.
3. Click Run Diagnostic Tests.
4. If all of the steps indicate “OK” then your PPPoE or PPPoA connection is up and working.
If you cannot connect after several minutes, you may be using an incorrect service name, user
name, or password. There also may be a provisioning problem with your ISP.
Note: Unless you connect manually, the modem router will not authenticate using PPPoE
or PPPoA until data is transmitted to the network.
Troubleshooting Internet Browsing
If your modem 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
servers for your use. If you entered a DNS address during the modem router’s configuration,
reboot your computer and verify the DNS address as described in the online document that
you can access from
configure your computer manually with DNS addresses, as explained in your operating system
documentation.
• Your computer may not have the modem router configured as its TCP/IP modem router.
If your computer obtains its information from the modem router by DHCP, reboot the
computer and verify the modem router address as described in the online document that you
can access from
Troubleshooting 6-7
addresses. Typically your ISP will provide the addresses of one or two DNS

Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings, changing the
modem 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 Rest button on the Backup Settings screen (see “Resetting the Configuration to the
Factory Default Settings” on page 2-3).
• Use the reset button on the rear panel of the modem 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 reset button on the rear panel of the modem router.
1. Press and hold the reset button until the Power LED turns red (about 10 seconds).
2. Release the reset button and wait for the modem router to reboot.
Problems with Date and Time
In the main menu, under Advanced, select Internet Time to display the current date and time of
day . The mo dem router us es the Network T ime Pr otocol (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 modem router has not yet successfully reached a network time server. Check that
your Internet access is configured correctly. If you have just completed configuring the
modem router, wait at least 5 minutes, and check the date and time again.
• Time is off by one hour.
Cause: The modem router does not automatically sense daylight saving time. In the Schedule
screen, select the Automatically adjust clock for daylight saving changes check box.
