Increase Your BitTorrent & P2P download speed in Windows Vista

Photo Sharing and Video Hosting at Photobucket

Here are a few tips to optimize and increase the download speed of BitTorrent as well as other P2P file sharing programs such as Kazaa, Gnutella, Shareaza, eDonkey, eMule, etc in Windows Vista.

1) If you are using a router from your ISP to connect to the internet, follow the below mentioned steps:

a) Open your router’s configuration page

b) Look for an option that says Port Range Forwarding, Port Range or Virtual Servers.(sometimes under NAT)

Note: If you can’t find step a or b, check out the routers section of portforward.com for your specific model

c) Add ports ranging from 6881-6999 (or the port you specifically use) and make sure to select both TCP and UDP.

d) Forward or map the above mentioned ports to the computer running the BitTorrent client.

The ports for P2P programs are as follows:

Gnutella (Shareaza)
TCP and UDP ports 6346

eDonkey and Overnet clones
TCP and UDP ports 4661-4672

Kazaa and other Fasttrack clones

TCP and UDP ports 1214

Ares Galaxy

TCP port 32285.

Winmx and Napster

TCP and UDP ports 6257

eMule
TCP and UDP ports 4661-4672 and TCP ports 5555,4242, 3306, 2323, 6667, 7778

2) If your ISP throttles BitTorrent bandwidth, there are two solutions:

a) Use a free VPN service such as SecureIX (mentioned here)

b) Use uncommon ports: A BitTorrent client normally associates the TCP port number 6881. However, if this port is busy for some reason, the client will instead try higher ports upto 6999. You can change the port that your BitTorrent client listens to ranging from 49152–65534 or an unassigned port between 1024–49151 by going to the configuration settings of the BitTorrent or the P2P file sharing client. Make sure to follow the steps listed in Step 1 to forward or map the ports to your computer from the router.

3) Configure your Anti Virus/Firewall software to allow TCP and UDP ports listed above

Comodo Personal Firewall (I recommend you use this firewall it is the most secure free firewall I know of )

Symantec Firewall

McAfee Firewall
Trend Micro Firewall
ZoneLabs (Zone alarm)
Windows Vista Firewall


Note: Some firewalls allow you configure ports based on the executable file name

4) Do not use Force Start: Force Start is used for starting a torrent manually. This torrent will be out of order from the queue. using Force Start will spread out your upload capacity over too many upload slots – and your overall download speed will actually suffer.

5) For Windows Vista OS limitations:

a) Increase the maximum limit of half-open TCP/IP concurrent connections using klitetools batch file

b) Set the TCP Auto Tuning to Highly Restricted by typing instead of completely disabling it:


netsh interface tcp set global autotuninglevel=highlyrestricted

This settings allows the TCP/IP window to grow beyond its default value.

If it restricting TCP/IP auto tuning doesn’t help, try disabling it altogether by typing:

netsh int tcp set global autotuninglevel=disable

A reboot of the computer is required after changing this setting

6) After changing the registry key in the OS, increase the maximum number of connections in the BitTorrent/P2P software itself.

    my mistake, but that is because utorrent came out only a few days before the post I made..I don’t use utorrent so I am not so current on what is going on. I just checked utorrent less then a week ago

    as for how to use the guide with utorrent, do you mean you don’t know how to configure ports?

    look here for a quick guide

    Hi, I have some trouble on the command. I executed the Patch32.bat files, and after a reboot, I open a command prompt and type in “netsh interface tcp set global autotuninglevel=highlyrestricted”, it give me “Set global command failed on IPv4 The requested operation requires elevation”. What should I do?

  8. redchaos Says:

    Did you run the command prompt as an administrator?

    To do this make a shortcut that points to “command.com”

    Then right click on the shortcut and click run as administrator see if that works

  9. SubZer0 Says:

    Thanks a lot. It works now. Another question, I’m currently using norton antivirus 360, I already set allow for all the bitcomet application usage at the firewall application rules and I already open DMZ as well as port forwarding on my router, but I still getting the yello sign saying that my listen port unreachable. Why and what should I do?
