uTorrent Port Checker is a free online service that allows you to check whether ports are open on your computer for use by the BitTorrent software.

Port forwarding is not something that needs to be configured in most situations. Basically, what it does is forward a connection to the local network to a specific local computer system.

A computer router, firewall, modem or other hardware device that manages or controls traffic is involved in the process usually as traffic hits it first before it is routed to a computer. So, to make sure that certain traffic lands on the right system, port forwarding may need to be configured.

Port forwarding can be a big issue when you run P2P applications like uTorrent, as an incorrectly configured router or other hardware device may reduce or even block the traffic to the local computer running the P2P application.

Port forwarding can be configured in the router or traffic controlling device. It involves setting up the router so that a certain port is always directed to a specific computer. This is done by specifying the computer you want the traffic to be directed to (using host name or IP), and the port that you want forwarded.

One of easiest ways to check if a port is properly forwarded is to use an online port checker like the one provided by uTorrent. To verify the port forwarding open the following url in your web browser and change the number at the end to the port that you want to forward.

The script checks if the port is forwarded properly:

The screenshot above confirms that port forwarding is set up correctly. If it is not, an error message is displayed instead. If that is the case, you should go back to the router's configuration panel to check the forwarding rules there.

Update: The port checker has now been integrated into the uTorrent client natively. You can open the port checker in uTorrent with a click on Options > Setup Guide.

You find the port listing at the bottom of the page. If you want to test a particular port simply enter it into the field and click on the run tests button afterwards.

The program displays the connection status after a couple of seconds in the same interface. Here you are then either informed that the port is accessible, or not.

So, the whole process looks like this now:

  1. Open uTorrent, and open the Setup Guide.
  2. Check that the current port is correct, and hit the run tests button.
  3. If you get the green light, everything is set up correctly.
  4. If you don't, you need to open the router or modem configuration to check the settings and adjust them accordingly.

    VLC Player has played just about every file for me. If VLC can’t play it, then the file was probably malicious anyways

      As I said, VLC should have you covered. But if you use Media Player or something similar, you may like this.

    Media Player Classic – Home Cinema (MPC-HC) or Media Player Classic – BE (MPC-BE) should be able to play (almost) anything also. MPC-BE is my player of choice. (It also has a small footprint on your hard drive, which is something I always take into consideration when choosing between different programs.)
