How to Unblock the Listening Port in Bitcomet

How to Unblock the Listening Port in Bitcomet

BitComet is a download manager client for Windows which enables users to download bit-torrent files from the internet. As with all bit-torrent applications, BitComet uses unique ports through which it sends and receives data, and this might require some additional configuration in both Windows and your router (if you use one).

If your downloads and uploads in BitComet are very slow, then this could well mean that the required ports are blocked. BitComet might also display a yellow light and message stating that “the listening port is blocked”.

Most data from the web (via HTTP) passes through the same port (80), and Windows will be automatically configured to allow this traffic through. This is not the case when downloading torrents, however, and you must instruct Windows to enable the data to pass through freely. Follow the steps below to learn how.

Step-by-Step Instructions

  • 1

    After installing Bitcomet, click the Windows Start button. Locate and click the Control Panel link on the right hand side of the Start menu. After a few seconds, the Control Panel is displayed.

  • 2

    Select System and Security to open the security preferences for Windows. Under Windows Firewall, choose Allow a program through Windows Firewall.

    The Allowed Programs window is displayed, which contains a list of every installed application on your computer.

  • 3

    Click Change Settings to enable editing mode of the list (all checkboxes are greyed out until this is selected). Locate BitComet in the list of applications displayed and if not already checked, click the box in the Home/Work (Private) column.

  • 4

    Click OK to close the Allowed Programs window.

    Switch to BitComet and commence or resume an existing download to see if the issue has been resolved.

Tips & Advice

  • If you are using Windows XP, you must also create an exception in Windows Firewall, but the process is slightly different:

    Click Start and choose Settings, Control Panel and Windows Firewall.

    Ensure Don’t allow Exceptions is unchecked.

    Click the Exceptions tab and locate the BitComet services in the list of applications. Check each one to allow it through the firewall.

    Click OK to save changes.

  • You might also need to set your router up to allow the BitComet traffic through, once Windows has been configured. Refer to the Related Links for some useful guides on how to do this.
  • Once BitComet is working as it should, be careful not to download copyrighted material from the internet. Any media that is commercially available in the shops or online is probably illegal to download, whichever country you are in, and can result in financial or custodial penalties.
