Application Example: Make a Local Web Server Public If you host a web server on your local network, you can use port forwarding to allow web requests from
anyone on the Internet to reach your web server.
To make a local web server public: 1.
Assign your web server either a fixed IP address or a dynamic IP address using DHCP address
reservation.
In this example, your 
modem always gives your web server an IP address of 192.168.5.33.
2. On the Port Forwarding page, configure the modem to forward the HTTP service to the local address
of y

our web server at 
192.168.5.33.
HTTP (por
t 80) is the standard protocol for web servers.
How the Modem Implements the Port Forwarding Rule The following sequence shows the effects of a port forwarding rule:
1.When you enter the URL www.example.com in your browser, the browser sends a web page request
message with the following destination information:
•Destination address. The IP address of www.example.com, which is the address of your modem.
• Destination port number. 80, which is the standard port number for a web server process.
2. The 
modem receives the message and finds your port forwarding rule for incoming port 80 traffic.
3. The modem changes the destination IP address in the message to 192.168.5\
.123 and sends the message
to that computer
.
4. Your modem performs Network Address Translation (NAT) on the source IP address and sends the
reply through the Inter
 net to the computer that sent the web page request. Manage Port Forwarding

							Quick Tips for Troubleshooting
If your network is unresponsive or does not function normally, try restarting your network:
1.Turn off and unplug the modem.
2. Plug in the modem, turn it on, and wait two minutes.
If network problems still occur, make sure that your ISP does not require you to use the MAC address
of the computer that was used to initially register the ISP account. If your ISP does require that you do
this, you must change the 
modem MAC address that the modem uses. For more information, see one
of the f
ollowing sections:
• Manually Set Up an ADSL Internet Connection on page 
29
• Manually Set Up a VDSL Internet Connection on page 
38
If you cannot connect over an Ethernet cable to the modem, try the following:
• Mak

e sure that the Ethernet cable is securely plugged in.
• Make sure that your computer or device does not use a static IP address but is configured to receive
an IP address automatically with DHCP. (For most devices, DHCP is the default setting.)
Troubleshoot With the LEDs When you turn on the power, the LEDs light as described here:
1.The LAN LED   lights solid green for about 12 seconds and then turns off.
2. When the LAN LED turns off, the Power LED   lights solid amber for about 40 seconds and then turns
solid green, indicating that the startup procedure is complete and the modem
 is ready.
3. When the Power LED lights solid green, verify that the DSL LED   is either solid green or is blinking
amber and then lights solid green.
You can use the LEDs for troubleshooting. For more information, see the following sections:
• Power LED Is Off
 on page 96
• Power LED Remains Solid Amber on page 97
• T

roubleshoot the Internet Connection on page 97
P

ower LED Is Off
If the Power LED   and other LEDs are off when your modem
 is turned on, do the following:
• Make sure that the Power On/Off
 button on the back is in the on position, that is, it is pushed in.
• Make sure that the power cord is correctly connected to your modem and that the power supply adapter
is correctly connected to a functioning power outlet.
• Make sure that you are using the 12V, 0.5A power adapter that NETGEAR supplied for this product. Troubleshooting

							If the error persists, a hardware problem might exist. For recovery instructions or help with a hardware
problem, contact technical support at netgear.com/support.
Power LED Remains Solid Amber
During the startup process, the Power LED   lights solid amber for about 40 seconds and then turns solid
green, indicating that the startup procedure is complete and the modem is ready.
If the P

ower LED remains solid amber and does not turn solid green, a failure occurred or the modem is
malfunctioning.
If the P

ower LED does not turn solid green, do the following:
1. Turn the power off and back on and wait several minutes to see if the 
modem recovers.
2. If the 
modem does not recover, press and hold the Reset button to return the modem to its factory
settings
.
If the error persists, a hardware problem might exist. For recovery instructions or help with a hardware
problem, contact technical support at 
netgear.com/support.
You Cannot Log In to the Modem If you are unable to log in to the modem from a computer and use the modem web pages, check the following:
•Check the Ethernet connection between the computer and the modem.
• Mak

e sure that the IP address of your computer is on the same subnet as the modem. If you are using
the recommended addressing scheme, your computer’s address is in the range of 192.168.5.2 to
192.168.5.254.
• Make sure that your computer can reach the modem’s DHCP server. Recent versions of Windows and
Mac OS gener

ate and assign an IP address if the computer cannot reach a DHCP server. These
autogenerated 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
 and reboot your computer.
• If your modem’s IP address was changed and you do not know the current IP address, clear the modem’s
configuration to factory defaults. This sets the modem’s IP address to 192.168.5.1. For more information,
see Return the Modem to Its Factory Default Settings on page 76
 and Factory Settings on page 105.
• Mak
e sure that Java, JavaScript, or ActiveX is enabled in your browser. If you are using Internet Explorer,
click the Refresh button to be sure that the Java applet is loaded.
• T

ry quitting the browser and launching it again.
• Make sure that you are using the correct login information. The user name is 
admin, and the default
pass
word is 
password. Make sure that Caps Lock is off when you enter this information.
Troubleshoot the Internet Connection If your 
modem cannot access the Internet, check the DSL connection, then the WAN TCP/IP connection. Troubleshooting

							Troubleshoot the DSL Link
If your modem is unable to access the Internet, first determine whether the DSL link with the service provider
is working. The DSL LED indicates the state of this connection.
DSL LED Is Solid Green
If the DSL LED 
 lights solid green, the DSL connection is good. You can be confident that the service
provider connected your line correctly and that your wiring is correct.
DSL LED Is Blinking Amber
If the DSL LED   is blinking amber, your modem is attempting to make a DSL connection with the service
provider. If the modem establishes a DSL connection, the DSL LED turns solid green. This connection
process gener
ally lasts several minutes.
If the DSL LED does not turn solid green, disconnect all telephones on the line. If this solves the problem,
reconnect the telephones one at a time, being sure to use a microfilter on each telephone. If the microfilters
are connected correctly, you can connect all your telephones.
If disconnecting telephones does not result in a solid green DSL LED, a problem with your wiring might exist.
If the telephone company tested the DSL signal at your network interface device (NID), then wiring in your
house might be of poor quality.
DSL LED Is Off
If the DSL LED   is off, disconnect all telephones on the line. If this solves the problem, reconnect the
telephones one at a time, being sure to use a microfilter on each telephone. If the microfilters are connected
correctly, you can connect all your telephones.
If disconnecting telephones does not result in a blinking amber or solid green DSL LED, check the following:
• Check to see that the telephone company made the connection to your line and tested it.
• Verify that you are connected to the correct telephone line. If more than one phone line is installed, be
sure that you are connected to the line with the DSL service. It might be necessary to use a swapper if
your DSL signal is on pins 1 and 4 or the RJ-11 jack. The 
modem uses pins 2 and 3.
Obtain an Internet IP Address
If the modem cannot access the Internet, see if the modem can obtain an Internet IP address from the ISP.
Unless the 
modem is assigned a static IP address, the modem requests an IP address from the ISP. You
can determine whether the request was successful using the 
modem’s web pages.
To check the Internet IP address: 1.
Launch a web browser from a computer that is connected to the network.
2. Enter 
http://www.routerlogin.net.
A login window opens.
3. Enter the 
modem user name and password.
The user name is 
admin. The default password is password. The user name and password are
case-sensitive. Troubleshooting

4. Select ADVANCED > ADVANCED Home.
The AD
VANCED Home page displays.
5. In the Internet Port pane, check to see that the IP Address field shows a valid IP address.
If the field shows 0.0.0.0, your modem did not obtain an IP address from your ISP.
If y

our 
modem cannot obtain an IP address from the ISP, the problem might be one of the following:
• Y
our Internet service provider (ISP) might require a login program. Ask your ISP whether they require
PPP over Ethernet (PPPoE) or some other type of login.
• If you selected a login program, the service name, user name, or password could be incorrectly set.
Before you make any changes, verify that the modem can get a PPPoE or PPPoA connection (see
V

erify the PPPoE or PPPoA Connection
 on page 99).
• Y
our ISP might check for your computer’s host name. Assign the computer host name of your ISP
account as the account name. For more information, see one of the following sections:
- Manually Set Up an ADSL Internet Connection on page 29
- Man

ually Set Up a VDSL Internet Connection on page 
38
• If your ISP allows only one Ethernet MAC address to connect to Internet and checks for your computer’s
MAC address, inform your ISP that you bought a new network device and ask them to use the modem’s
MAC address.
• Configure your 
modem to clone your computer’s MAC address. For more information, see one of the
following sections:
