How to Enable Port Forwarding

How-To Enable-Port-Forwarding

If you have ever used BitTorrent clients like uTorrent or BitComet you are probably aware of the term port forwarding. Most modern routers have UPnP (Universal Plug ‘n Play) or NAT-PMP built in, which allows automatic forwarding of ports. However, others need to forward a port manually. If you get the yellow icon in uTorrent or other torrent clients, then you need to forward your port (if it is red, then the probable culprit is your Firewall). But before discussing how to forward a port, let us first learn the meaning of port forwarding.

Arrow What is Port Forwarding?

The Physical Address and IP Address allow data packets to travel from the source to the destination host. However, the destination machine is not the final target. There may be multiple programs requesting different kinds of data simultaneously. Software ports are basically numbered connections that are used by the computer to sort the network traffic. In other words ports allow the computer to send the correct data to the correct process. Conventionally, port 80 is used for HTTP traffic, port 21 for FTP and so on. You can find a list of various ports used by various services over here.

Now that we know what ports are, let us come to port forwarding. Port forwarding is basically forwarding a network port from one node to another. It is also called port mapping or tunneling. It allows an outside user to access a certain port through a NAT enabled router. Without port forwarding you won’t be visible to a lot of users. This is why you must enable port forwarding in order to get optimal speeds with torrent downloads.

    Port fowarding is usually enabled on all routers, its a matter of putting in the correct settings. You need to know the port # to foward and the destination address. Then you can configure your router.

    Your router needs to be configured to permit port forwarding to a static LAN IP address. First assign the pc to which you wish the port to forward a static LAN IP address that is NOT in the DHCP pool and that is not used elsewhere. Then log onto router configuration and go to port forwarding section and initiate the port forwarding.

    Great article, could have done with this a couple of years ago when I had a different router and it was a nightmare to keep going in and sorting the ports out….. Stumbled this!
