Port Forwarding to allow faster torrent downloads

If you are getting absymally low sppeds while dowloading using torrent links then this article may help you out greatly.

The torrent network is based on P2P (peer to peer) technology which means that while you are happily downloading some stuf ,someone else is simultaneously downloading from your already downloaded data. This ensures that maximum speed is achieved. But nowadays users having personal broadband connection have a router which connects them to their ISP. These router come with a prebuilt firewall which filter out incoming packets and only allow packets bound to certain ports.

Usually torrent clients such as utorrent require ports in the range of 5000 and onwards to be "opened" for peers to connect to you but the router does not allow it. While downloading a file in utorrent check whether there is a tick or a cross at the bottom bar of utorrent. If there is no signal present your internet connection is probably not working . A green coloured tick means that utorrent is working perfectly fine otherwise if there is a red cross then you will have to instruct your router to forward all the packets that it is blocking to your computer.

Port forwarding allows you to forward all the packets bound to a certain port or ip address without any hindrance from the router. Obviously to do this you would need full access to your router.

Usuallly all routers have a web server and telnet server running TO access the webserver , open your web browser and enter , (if you get an error you have either entered a worng address or the web server is not running)

Now youll probably be asked for username and password to access the webpage:
The default usernames and passwords are generally in the form of:

Once you have access to the web page search for the links such as Port forwarding , Virtual Severs or DMZ HOST or port triggering.

I have a beetel 440bx wireless router at home and port forwarding can be done by using the virtual servers settings.

Select the protocols as TCP&UDP and enter the port that is specified in utorrent settings for both the "Internal port end" and "External port End".

In the "Server IP address " settings enter the IP of the host computer.

Save the settings and reboot the router.

Port triggering is a newer feature in which "outbound" and "inbound" ports are specified. Now as soon as a packet leaves the router from the "outbound" port, it will instantly allow all packets in through the specified "inbound" port to that host which caused the traffic. It is not a very user-friendly technique and causes problems if your application uses a different port each time.

DMZ host basically allows the router to forward all the packets from outside to the specified IP address.

Also remember to assign your computer a static IP address so that you dont have to change settings in the router.

If the settings are entered correctly you will get a nice green tick at the bottom of u torrent
