The Best Port Settings for Bit Torrent Downloading

Updated April 17, 2017

BitTorrent is a file transfer protocol that connects your computer to other computers that have the file you want to download. Instead of downloading the file from one server, as with FTP services, BitTorrent allows you to download small pieces of the file from multiple computers. In order for BitTorrent to work properly, you need to make sure your computer can open and receive connections to other computers. By adjusting the port settings on your computer, you can increase your BitTorrent download and upload speeds.

Open a command prompt on your computer. Press "Windows+R" and type "cmd" into the prompt. When the prompt appears, type "ipconfig /all" and press "enter." You will need to set up a static IP address on your computer to optimise the port settings for your BitTorrent client.

Write down the numbers corresponding to the "IP Address," "Subnet Mask," "Default Gateway," and "DNS Server" fields. Close the command prompt and open the "Network Connections" window from the "Control Panel."

Double-click on the network connection you use to connect to the Internet. Click the "Properties" button to access the connection properties. Select "Internet Protocol TCP/IP" and click "Properties."

Select "Use the following IP Address" to set up a static IP address for your computer. Enter the data copied in step 2 into the respective fields of the properties window and click "OK." Close the network connection property windows.

Open a web browser and enter your router's IP address into the browser's address bar. Log into your router and navigate to the "Port Forwarding" set-up screen. Different routers have different locations for the "Port Forwarding" set-up, so consult your router's documentation if you have trouble finding the screen.

Add a new application to port forwarding. Enter "Torrent" in the "Application" field. By default, BitTorrent uses the port ranges 6881-6889. Under the "External Port Range" field, enter "6881" in the first field and "6889" in the second field.

Check both the "TCP" and "UDP" boxes. In the "IP Address" field, enter the IP address you assigned your computer in step 4. Check the "Enable" box and click the "OK" or "Apply" button to save your settings. These settings will tell your router to send all incoming BitTorrent traffic on ports 6881-6889 to your computer.

Open your BitTorrent client and test your new settings to make sure they work properly. Your BitTorrent speeds will be noticeably faster when downloading files that have healthy seed levels.


If your computer fails to connect to the Internet after changing to a static IP address in step 4, the fault is most likely due to an incorrect value entered in the "DNS Server" fields. Contact your Internet Service Provider to get the correct values to enter in the "DNS Server" fields.
