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.
Specify Internet Port Settings 174 Nighthawk X6 AC3200 Tri-Band WiFi Router 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 in the message to IP address 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. 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 53.
Specify Internet Port Settings 175 Nighthawk X6 AC3200 Tri-Band WiFi Router Add a Port Triggering Service To add a port triggering service: 1. Launch an Internet browser from a computer or wireless device that is co\ nnected to the network. 2. T ype 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 ADV ANCED > Advanced Setup > Port Forwarding/Port Triggering. The Port Forwarding/Port Triggering screen displays. 5. Select the Port T riggering radio button. 6. Click the Add Service button. 7. In the Service Name field, type a descriptive service name. 8. From the Service User list, 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 list, 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 Connection T ype, Starting Port , and Ending Port fields. 12. Click the Apply button. The service is now in the Portmap table. You must enable port triggering before the router uses port triggering. See Enable Port Triggering on page 176.
Specify Internet Port Settings 176 Nighthawk X6 AC3200 Tri-Band WiFi Router Enable Port Triggering To enable port triggering: 1. Launch an Internet browser from a computer or wireless device that is co\ nnected to the network. 2. T ype 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 ADV ANCED > Advanced Setup > Port Forwarding/Port Triggering. The Port Forwarding/Port Triggering screen displays. 5. Select the Port T riggering radio button. 6. Clear the Disable Port Triggering check box. If this check box is selected, the router does not use port triggering e\ ven if you have specified port triggering settings. 7. 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. 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
Specify Internet Port Settings 177 Nighthawk X6 AC3200 Tri-Band WiFi Router 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 also allow incoming traffic on port 113 to reach the originating computer.” The following sequence shows the effects of this port triggering rule: 1. You open an IRC client program to start a chat session on your computer. 2. Your IRC client composes a request message to an IRC server using a destination port number of 6667, the standard port number for an IRC server process. Your computer then sends this request message to your router. 3. Your router creates an entry in its internal session table describing this 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 number of 6667, your router creates another session entry to send any incoming port 113 traffic to your computer. 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.

Troubleshooting 179 Nighthawk X6 AC3200 Tri-Band WiFi Router 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.
Troubleshooting 180 Nighthawk X6 AC3200 Tri-Band WiFi Router Troubleshoot with the LEDs By default, the router is set with standard LED settings. If you disable\ d blinking for the LEDs or turned off all LEDs except the Power LED, you must return the LEDs to their stand\ ard settings for troubleshooting. For information about controlling the LED \ settings, see Position Your Router on page 12. Standard LED Behavior When the Router is Powered On After you turn on power to the router, the following sequence of events \ occurs: 1. When power is first applied, verify that the Power LED is lit. 2. After approximately 30 seconds, verify the following: • The Power LED is solid white. • The Internet LED is lit. • The WiFi LED is lit unless you turned of f the wireless radio. You can use the LEDs on the front panel of the router for troubleshooting\ . Power LED Is Off or Blinking • 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, you have a hardware problem. For recove\ ry 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 turns amber for about 20 sec\ onds and then turns white. If the LED does not turn white, the router has a problem.
