Use this setting if you want to manually assign a specific IP address to the router while it functions in access point mode.
11 Manage Port Forwarding and Port Triggering You can use port forwarding and port triggering to set up rules for Internet traffic for services and applications. You need networking knowledge to set up these features.
AC1200 WiFi Router Model R6120 Manage Port Forwarding to a Local Server for Services and Applications If a server is part of your network, you can allow certain types of incoming traffic to reach the server. For example, you might want to make a local web server, FTP server, or game server visible and available to the Internet. The router can forward incoming traffic with specific protocols to computers on your local network.
AC1200 WiFi Router Model R6120 If the service or application that you want to add is not in the list, create a port forwarding rule with a custom service or application (see Add a Port Forwarding Rule With a Custom Service or Application on page 130). 9.

AC1200 WiFi Router Model R6120 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.
AC1200 WiFi Router Model R6120 Manage Port Triggering for Services and Applications 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.
AC1200 WiFi Router Model R6120 5. Select the Port Triggering radio button. The port triggering settings display. 6. Click the Add Service button. The Port Triggering Rules page displays. 7.

The user name is admin.
AC1200 WiFi Router Model R6120 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.
12 Troubleshooting This chapter provides information to help you diagnose and solve problems you might experience with your router. If you do not find the solution here, check the NETGEAR support site at netgear.com/support for product and contact information.
AC1200 WiFi Router Model R6120 Reboot the Router From Its Web Interface You or NETGEAR technical support can reboot the router from its web interface, either locally or remotely, for example, when the router seems to be unstable or is not operating normally. To reboot the router from its web interface: 1. Launch a web browser from a computer or mobile device that is connected to the network. 2. Enter http://www.routerlogin.net. A login window opens. 3. Enter the router user name and password.
AC1200 WiFi Router Model R6120 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 devices are connected to the router by an Ethernet cable, the corresponding numbered router LAN port LEDs light.
AC1200 WiFi Router Model R6120 You can use the LEDs on the front panel of the router for troubleshooting. Power LED Is Off or Blinking This could occur for a number of reasons. Check the following: • Make sure that the power adapter is securely connected to your router and securely connected to a working power outlet. • Make sure that you are using the power adapter that NETGEAR supplied for this product. • If the Power LED blinks slowly and continuously, the router firmware might be corrupted.
AC1200 WiFi Router Model R6120 • Make sure that power is turned on to the connected modem and connected devices. • Be sure that you are using the correct cables. When you connect the router’s WAN port to a modem, use the cable that was supplied with the 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.
AC1200 WiFi Router Model R6120 • If you are attempting to set up your router as a replacement for an ADSL gateway in your network, the router cannot perform many gateway services. For example, the router cannot convert DSL or cable data into Ethernet networking information. NETGEAR does not support such a configuration. You Cannot Access the Internet If you can access your router but not the Internet, check to see if the router can obtain an IP address from your Internet service provider (ISP).
AC1200 WiFi Router Model R6120 If your router is still unable to obtain an IP address from the ISP, the problem might be one of the following: • Your 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 your ISP requires a login, the login name and password might be set incorrectly. • Your ISP might check for your computer’s host name.
