Remove the restriction of network traffic in the firewall

To fully understand the topic, you need to decide on the concept of a firewall (it is also called a firewall), and what it is for. A firewall is a special firewall that first appeared in Windows XP SP2. He replaced the well-known at the time Internet Connection Firewall. Its main purpose is to control the access of various programs to the network. Subsequently, similar programs began to appear from third-party software manufacturers. By default, the firewall is enabled on any operating system, but it can be turned off in different builds of one or another OS.

Problems with the torrent client

It often happens that when using a firewall it is impossible to download files through a torrent, because the incoming traffic does not flow to your computer. To remedy the situation, it is necessary to make some changes in the settings of the torrent client, namely to allow the ports that the client uses. This should be done carefully, because instead of correcting the situation, you can completely block access to the Internet to other programs, and they will not be able to connect to the Internet.

Configure the firewall

To make network traffic available to the torrent client, we will open ports in the firewall. Consider the example of Windows 7. Click Start - Control Panel - Security Center (or System and Security). In the window that opens, we are directly interested in the firewall. Go to its settings. Going to the tab "Allow programs to run or component through Windows Firewall", we need to add a torrent client program. If after all the above, downloading is still impossible, then, most likely, the problem is different. Blocking of torrent sites can occur on an external firewall. As a rule, it is placed on the resources of the provider in order to protect its customers from hacking and theft of personal data. In this case, you can not do without the help of a system administrator.

If your ports are blocked, you need to do the following (depending on the client, the names of the items and sub-items may differ):

  • We open the torrent client;
  • Go to Settings - Configuration - BitTorrent;
  • We expose compulsory protocol encryption;
  • Restart the client.

All these actions can only lead to partial improvement, namely the ability to download files at low speed. If you encounter such a nuisance, you must contact the support service of your provider. Another option to correct the situation is to use a proxy server. In addition, some routers have their own firewall, which is built into their firmware. To make the necessary changes inside the device, you must follow the instructions for use of a particular router model. If it is not included, then the right decision is to contact the support service of the company that manufactures your wireless router model.
