Configure a LAN to easily restrict BT downloads

With the popularization of broadband, we upgraded from the original kitten to the high-speed optical cable, and the speed of Internet access has indeed increased a lot, but it is not a long time. With the increasing number of users who use BT to download, the network speed is also getting slower and slower. More and more people like to use BT to download software and movies in enterprises, communities, and Internet cafes. This will seriously affect the network of other users. How can we limit the use of BT in the network? How can I release the network bandwidth that is heavily occupied by BT? The following describes how to use a vro to restrict access.

I. Block common P2P ports

We know that the network protocol communicates through certain ports. In general, the TCP port used by BT is 6881-6889, you only need to disable these ports in the vro or firewall, so that you can use BT to download the software.
Let's take the aitai 2610 vro as an example to introduce the method. First, create a policy to block these ports. First, name the policy, such as BT1, and then select the TCP protocol below, enter the Start port as 6881, end port as 6889, source start port as 1, and source end port as 65535. Keep the default value for other ports and click "save.

In this way, the btsoftware will not be downloaded through the above port, but now many btsoftware can modify the port number, so we can according to the actual usage, without affecting normal business, close all ports as much as possible to reduce the BT download probability.

Ii. Seed server closed

We know that downloading BT requires downloading the seed file first, and then linking to the server for downloading. We can use the seed server closed approach so that the btsoftware cannot connect to the server, in this way, BT download is restricted.

This method is illustrated by taking atai 2610 as an example. First, the network administrator searches for popular BT sites, and then obtains the IP addresses of these sites and their mirror sites, such as the IP address of the http://bt.btchina.net site is 222.208.183.15, we can create a new policy, set both the destination start address and destination end address to the IP address. Keep the default value for other settings, and click Save. In this way, all users in the LAN do not need to connect to the website.

This method is very effective, but the network administrator needs to collect a large amount of website information to ensure that all BT download sites are restricted, however, it takes a lot of time to collect the website information .. In addition, you can filter these websites by restricting URLs.

3. Restrict downloading of BT seeds

If you can restrict the download of BT seeds, you can also restrict the download of BT seeds. We know that the BT seed file names are ". torrent "is a suffix file, so we can use this function to filter it and restrict its download.
Vro provides the web page string control function. Open the firewall settings of the vro, click "webpage content control", and select the check box before "Activate webpage String Control, enter ". torrent, and then click "Update string". Then, the string is added to the restricted list.

In addition, you can set the time limit for downloading BT files so that you can use BT to download required files during non-working hours. You can set the time limit according to your needs, finally, click "OK", so that it will not be downloaded. torrent is a BT file with the extension.

4. restrict the use of specific software

Some vro manufacturers have built-in software restriction functions in the vro to facilitate user use. After the software is selected, the specified machine can restrict the use of the BT download software, this restricts the user's BT download.

For example, the g0000500 router of xiaonuo provides this function. You only need to open the "Block specific service bar" under the firewall configuration, and then select the btsoftware of the software to be downloaded, such as BT thunder, next, set the IP address of the machine that is not restricted to download, so that you can easily limit the download of BT.

This function is the easiest to set. Anyone can set it, but this method is also limited. Only a few vrouters provide this function, in addition, the limited number of BT download software is relatively small, and it is not allowed to completely limit all BT download software.

5. Speed Limit of machines in the Network

We also need to impose unified speed limits on all hosts in the network so that the bandwidth of each machine in the network is completely consistent, thus ensuring the speed of all machines, even if someone uses BT to download, it will not affect other people who are working.

Click the "advanced configuration/special functions" tab in the aitai 2610 vro to limit the Intranet host speed. You can set the upload and download speeds here, in this way, all machines in the LAN will have a unified speed, and will never be affected by each other.

This method can be used to restrict BT downloads so that you are no longer affected by BT downloads. However, this method distributes the bandwidth evenly. If some computers are not enabled, A part of the bandwidth is also allocated, and the users who are using the bandwidth can only use the specified bandwidth, which is a waste of bandwidth.

6. Manage broadband services

Managing the total bandwidth allocated by the ISP can also restrict the download of BT without interference from other users.

Set the ISP allocation bandwidth and the allocation bandwidth of the Group in the bandwidth allocation, and set the priority to high, do not select the check boxes after "Allow to borrow bandwidth from other groups" and "allow this group to borrow bandwidth when it is empty", so that other groups cannot return the borrowed bandwidth in time, it can only be returned after the download is complete, affecting the network usage of other users.

This method can also limit the download of BT.

The six methods provided above can be used according to your actual situation, in this way, we can effectively control the BT download in the network, so that users who use BT download can release the bandwidth and create a high-speed and stable network for everyone.
