    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 router always gives your web server an IP address of 192.168.1.33. 
    2. In the Port Forwarding/Port Triggering screen, configure the router to forward the HTTP 
    service to the local address of your web server at 192.168.1.33. 
    HTTP (port 80) is the standard protocol for web servers.
    3. (Optional) Register a host name with a Dynamic DNS service and specify that name in the 
    Dynamic DNS screen of the router. 
    Dynamic DNS makes it much easier to access a server from the Internet because you 
    can type the name in the Internet browser. Otherwise, you must know the IP address that 
    the ISP assigned, which typically changes.
    How the Router Implements the Port Forwarding Rule
    The following sequence shows the effects of a port forwarding rule:
    1. When you type 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 router.
    •Destination port number. 80, which is the standard port number for a web server 
    process.
    2. Your router receives the message and finds your port forwarding rule for incoming port 80 
    traffic. 
    3. The router changes the destination IP address in the message to 192.168.1.123 and sends 
    the message to that computer.
    4. Your web server at IP address 192.168.1.123 receives the request and sends a reply 
    message to your router. 
    						
    							Specify Internet Port Settings 
    143  N600 WiFi Dual Band Gigabit Router
    5. Your router performs Network Address Translation (NAT) on the source IP address and 
    sends the reply through the Internet to the computer or wireless device that sent the web 
    page request. 
    Set Up Port Triggering
    Port triggering is a dynamic extension of port forwarding that is useful in these cases:
    •An application must use port forwarding to more than one local computer (but not 
    simultaneously).
    •An application must open incoming ports that are different from the outgoing port.
    With port triggering, the router monitors traffic to the Internet from an outbound “trigger” port 
    that you specify. For outbound traffic from that port, the router saves the IP address of the 
    computer that sent the traffic. The router temporarily opens the incoming port or ports that 
    you specify in your rule and forwards that incoming traffic to that destination.
    Port forwarding creates a static mapping of a port number or range of ports to a single local 
    computer. Port triggering can dynamically open ports to any computer when needed and 
    close the ports when they are no longer needed.
    Note:If you use applications such as multiplayer gaming, peer-to-peer 
    connections, real-time communications such as instant messaging, or 
    remote assistance (a feature in Windows XP), enable Universal Plug 
    and Play (UPnP). See 
    Improve Network Connections with Universal 
    Plug and Play on page 45.
    Add a Port Triggering Service
    To add a port triggering service:
    1. Launch a web browser from a computer or wireless device that is connected to the 
    network.
    2. Type http://www.routerlogin.net or http://www.routerlogin.com.
    A login screen displays.
    3. Enter the router user name and password.
    The user name is admin. The default password is password. The user name and 
    password are case-sensitive.
    The BASIC Home screen displays.
    4. Select ADVANCED > Advanced Setup > Port Forwarding/Port Triggering. 
    The Port Forwarding/Port Triggering screen displays.
    5. Select the Port Triggering radio button.

    6. 
    Click the  Add Service button.
    7. In the Service Name (If Required)  field, type a descriptive service name. 
    8.  From the Service User menu, select a user option:
    • Any (the default) allows any computer on the Internet to use this service\
    . 
    • Single address restricts the service to a particular computer
     . 
    9.  From the Service T
     ype menu, select TCP or  UDP or TCP/UDP (both). 
    If you are not sure, select TCP/UDP .
    10.  In the  T
    riggering Port  field, enter the number of the outbound traffic port that will open the 
    inbound ports. 
    11.  In the Service T
     ype, Starting Port, and Ending Port  fields, enter the inbound connection 
    information.
    12.  (Optional) In the  Port T
     riggering Timeout field, enter a value up to 9999 minutes. 
    This value controls how long the inbound ports stay open when the router\
     detects no  activity
     . This value is required because the router cannot detect when the applica\
    tion 
    terminates.
    13.  Click the  Apply button.
    The service is now in the Portmap Table. 
    Disable Port Triggering
    You can disable port triggering. The port triggering services that you set up are saved but are  not used.
    To disable port triggering: 
    1.  Launch a web browser from a computer or wireless device that is connecte\
    d to the 
    network.
    2.  T

    The Port Forwarding/Port Triggering screen displays.
    5.  Select the Port T
     riggering radio button.
    6. Select the Disable Port Triggering  check box.
    If this check box is selected, the router does not use port triggering e\
    ven if you specified 
    port triggering settings.
    Application Example: Port Triggering for Internet Relay Chat 
    Some application servers, such as FTP and IRC servers, send replies to m\
    ultiple port 
    numbers. Using port triggering, you can tell the router to open more inc\
    oming ports when a 
    particular outgoing port starts a session.
    An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at  destination port 6667. 
     The IRC server not only responds to your originating source port but 
    also sends an “identify” message to your computer on port 113. Using port triggering, you can 
    tell the router, “When you initiate a session with destination port 6667, you must a\
    lso allow 
    incoming traffic on port 113 to reach the originating computer.” The following sequence 
    shows the effects of this port triggering rule:
    1.  Y
    ou open an IRC client program to start a chat session on your computer. 
    2. Y
    our IRC client composes a request message to an IRC server using a desti\
    nation port 
    number of 6667, the standard port number for an IRC server process. Your computer then 
    sends this request message to your router.
    3.  Y
    our router creates an entry in its internal session table describing thi\
    s communication 
    session between your computer and the IRC server. Your router stores the original 
    information, performs Network Address Translation (NAT) on the source address and port, 
    and sends this request message through the Internet to the IRC server. 
    4.  Noting your port triggering rule and observing the destination port numb\
    er of 6667, your 
    router creates another session entry to send any incoming port 1
    
    13 traffic to your computer. 
    						
    							Specify Internet Port Settings 
    146 N600 WiFi Dual Band Gigabit Router 
    5. The IRC server sends a return message to your router using the NAT-assigned source port 
    (for example, port 33333) as the destination port and sends an “identify” message to your 
    router with destination port 113.
    6. When your router receives the incoming message to destination port 33333, it checks its 
    session table to see if a session is active for port number 33333. Finding an active session, 
    the router restores the original address information replaced by NAT and sends this reply 
    message to your computer.
    7. When your router receives the incoming message to destination port 113, it checks its 
    session table and finds an active session for port 113 associated with your computer. The 
    router replaces the message’s destination IP address with your computer’s IP address and 
    forwards the message to your computer.
    8. When you finish your chat session, your router eventually senses a period of inactivity in the 
    communications. The router then removes the session information from its session table and 
    incoming traffic is no longer accepted on port numbers 33333 or 113.

    Quick Tips
    This section describes tips for troubleshooting some common problems.
    Sequence to Restart Your Network
    When you need to restart your network, follow this sequence:
    1. Turn off and unplug the modem. 
    2. Turn off the router.
    3. Plug in the modem and turn it on. Wait two minutes.
    4. Turn on the router and wait two minutes.
    Check Ethernet Cable Connections
    If your device does not power on, make sure that the Ethernet cables are securely plugged 
    in. The Internet LED on the router is lit if the Ethernet cable connecting the router and the 
    modem is plugged in securely and the modem and router are turned on. If one or more 
    powered-on computers are connected to the router by an Ethernet cable, the corresponding 
    numbered router LAN port LED lights. 
    Wireless Settings
    Make sure that the wireless settings in the computer and router match exactly. The wireless 
    network name (SSID) and wireless security settings of the router and wireless computer must 
    match exactly. 
    If you set up an access list in the Advanced Wireless Settings screen, you must add each 
    wireless computer’s MAC address to the router’s access list.
    Network Settings
    Make sure that the network settings of the computer are correct. Wired and wirelessly 
    connected computers must use network (IP) addresses on the same network as the router. 
    The simplest way to do this is to configure each computer to obtain an IP address 
    automatically using DHCP. 
    Some cable modem service providers require you to use the MAC address of the computer 
    initially registered on the account. You can view the MAC address in the Attached Devices 
    screen.

    Troubleshoot with the LEDs
    You can use the LEDs to identify setup or performance problems in the rou\
    ter and to isolate 
    the cause.
    Standard LED Behavior When the Router Is Powered On
    After you turn on power to the router, make sure that the following sequ\
    ence of events  occurs:
    1.  When power is first applied, verify that the Power LED 
     is lit.
    2.  After about two minutes, verify the following:
    • The Power LED is solid green.
    • The Internet LED 
     is lit.
    • The WiFi LED 
     is lit unless you turned off the wireless radios.
    You can use the LEDs on the front panel of the router for troubleshooting\
    .
    Power LED Is Off or Blinking
    Do the following:
    • Make sure that the power adapter is securely connected to your router an\
    d securely 
    connected to a working power outlet. 
    • Check that you are using the power adapter that NETGEAR supplied for thi\
    s product.
    • If the Power LED blinks slowly and continuously
     , the router firmware is corrupted. This 
    can happen if a firmware upgrade is interrupted, or if the router detect\
    s a problem with the 
    firmware. If the error persists, a hardware problem might be the cause. \
    For recovery 
    instructions, or help with a hardware problem, contact technical support\
     at 
    www.netgear.com/support.
    Power LED Stays Amber
    When the router is turned on, the Power LED lights amber for up to two m\
    inutes and then 
    turns green. If the LED does not turn green, this indicates a problem wi\
    th the router.
    If the Power LED is still amber three minutes after you turn on power to\
     the router, do the 
    following:
    1.  T
    urn off the power and then turn it back on to see if the router recovers.
    2.  Press and hold the  Reset button to return the router to its factory settings. 
    See Factory Settings on page  158.
    If the error persists, a hardware problem might be the cause. Contact te\
    chnical support at

    LEDs Never Turn Off
    When the router is turned on, the LEDs light for about 10 seconds and then turn off. If all the 
    LEDs stay on, this indicates a fault within the router.
    If all LEDs are still lit one minute after power-up, do the following:
    •Cycle the power to see if the router recovers.
    •Press and hold the Reset button to return the router to its factory settings. For more 
    information, see 
    Factory Settings on page 158.
    If the error persists, a hardware problem might be the cause. Contact technical support at 
    www.netgear.com/support.
    Internet or Ethernet Port LEDs Are Off
    If either the Ethernet port LEDs or the Internet 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 modem 
    or computer.
    •Make sure that power is turned on to the connected modem or computer.
    •Be sure that you are using the correct cable.
    When connecting the router’s Internet port to a cable or DSL modem, use the cable that 
    was supplied with the cable or DSL modem. This cable can be a standard 
    straight-through Ethernet cable or an Ethernet crossover cable.
    WiFi LED Is Off
    If the WiFi LED stays off, check to see if someone pressed the WiFi On/Off button on the 
    router. This button turns the wireless radios in the router on and off. The WiFi LED is lit when 
    a wireless radio is turned on.
    Cannot Log In to the Router
    If you are unable to log in to the router 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.
    •Make sure that the IP address of your computer is on the same subnet as the router. If 
    you are using the recommended addressing scheme, your computer’s address is in the 
    range of 192.168.1.2 to 192.168.1.254. 
    •If your computer’s IP address is shown as 169.254.x.x, it is because recent versions of 
    Windows and Mac OS generate 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
