You can utilize this post to configure port forwarding routers NETGEAR interface.

Before we start up representing the way to configure port forwarding routers NETGEAR interface, let’s define “Port Forwarding” and what is the difference between it and “Port Triggering”?

By default NETGEAR router has a firewall blocks any connection by other devices in the public network “internet” to devices in your local network. So, if you want to allow specific connections to your local network, you must reconfigure the router.

Port Forwarding:

Port forwarding allows new connections “from the public network which may be blocked by the router to a certain port or port range” to go to a designated LAN machine. The ports are determined by the kind of server you want to run, (for example port 80 for a web server) and the IP is the private LAN IP of your web server. We will configure port forwarding routers NETGEAR interface.

Port Triggering:

Port triggering allows new connection from the outside to a certain port to go whatever LAN machine to make a specific outgoing connection which is defined by destination port.

For example:

You have two numbers (25, 113) one of them will be defined as trigger “25” and the other will be defined for the port number “113”. If any of your LAN machines creates an outgoing connection (=trigger) to port 25 “for example sending an email”, all of the incoming connection to port 113 will be temporarily routed to that machine. And then after a timeout, new connections to 113 will again be dropped.

Now returning to our main subject, how to configure port forwarding routers NETGEAR interface?

  1. First thing to do, go to a web browser and type this URL in the address bar.
  2. A screen will prompt to you to insert your username and password of the router, most of routers take “admin” as a username, and “password” as a password by default unless you have changed the logins before, so insert your own username and password.
  3. Tap on Advanced tab, choose Advanced Setup, and then select Port Forwarding/Port Triggering.Configure port forwarding routers NETGEAR interface
  4. As you see in the above screenshot, there are two options you can select one of them as the service type “Port Forwarding” and “Port Triggering”, choose the Port Forwarding radio button.
  5. From the Service Name drop-down menu select the service or game you want to host on your local network. In the case you do not find the service in this list, try to find “To add a custom service” instructions.
