BTGuard To Anonymize Bittorrent Traffic

Use BTGuard To Anonymize Bittorrent Traffic

If you're using BitTorrent without taking special measures to hide your activity, it's just a matter of time before your ISP throttles your connection, sends you an ominous letter, or worst case, your ISP gets a subpoena from a lawyer asking for your identity for a file-sharing law suit. Here's how to set up a simple proxy to keep your torrenting safe and anonymous. 

Note, you don't need to be doing anything illegal. Maybe you just want to keep Big Brother out of your business and from throttling your connection. Either way, if you really want to keep your activity private, your best bet involves routing your BitTorrent connection through an external service. BTGuard is a dead simple BT-focused proxy server and encryption service, and it's my service of choice. Below, I'll explain what it does, how it works, and how to set it up to privatize and anonymous your BT traffic.

How BTGuard Works

When you download or seed a torrent, you're connecting to a bunch of other people, called a swarm, all of whom—in order to share files—can see your computer's IP address. That's all very handy when you're sharing files with other netizens, but file sharers such as yourself aren't necessarily the only people paying attention. Piracy monitoring groups (often paid for by the entertainment industry either before or after they find violators) also join BitTorrent swarms, but instead of sharing files, they're logging the IP addresses of other people in the swarm—including you—so that they can notify your ISP of your doings.A proxy(like BTGuard) funnels your internet traffic—in this case, just your BitTorrent traffic—through another server, so that the BitTorrent swarm will show an IP address from a server that can't be traced back to you instead of the address that points to your house. That way, those anti-piracy groups can't contact your ISP, and your ISP has no cause to send you a harrowing letter.

But wait, can't the piracy groups then go to the anonymizer service (BTGuard) and requisition their logs to figure out that you're the one downloading the new Harry Potter? Theoretically, yes, but the reason why we chose BTGuard is because they don't keep logs, so there's no paper trail of activity leading back to you. All the piracy monitors see is BTGuard sharing a file, and all your ISP sees is you connecting to BTGuard—but not what data you're downloading, because it's encrypted.If you subscribe to an ISP that throttles BitTorrent traffic, and aren't using an anonymizer service, you have an additional problem. Your ISP can still see what you're doing, and if they detect that you're using BitTorrent—even if you're using it for perfectly legal purposes—they'll throttle your connection so you get unbearably slow speeds. When you encrypt your BitTorrent traffic, your ISP can't see what you're using your connection for. They'll see that you're downloading lots of information, but they won't be able to see that it's BitTorrent traffic, and thus won't throttle your connection. You still have to be careful of going over your ISP's bandwidth cap, however, if that exists.BTGuard offers you both a proxy (to combat spying) and encryption (to combat throttling)—though many torrent clients have encryption built-in as well.First, BTGuard isn't free. At $7/month (as little as $5 if you pay for a year in advance), it isn't very expensive, and we think it's well worth it if you want to torrent anonymously. A law suitsettlement, if it comes to that, will cost you at least a couple thousand dollars, which equals a couple decades of BTGuard subscriptions, so keep that in mind, too. The other potential downside is that piping your downloads through another service may decrease your upload and download speeds. How much depends on what torrent you're downloading, who from, and a lot of other factors, but just know that it's a possibility. In my experience, more popular torrents stayed at their top speed of 1.4 MB/s (my bandwidth cap) with a proxy, while other less popular torrents (which flew at 1.4MB/s without a proxy) would fluctuate around 200 or 300 kB/s with BTGuard in place. Again, though, a little longer wait on downloads is well worth the protection you get.Lastly, proxies aren't supported by every client, which means you'll have to use one with more advanced features. uTorrent (for Windows) and Vuze (for Windows, Mac, and Linux) both support proxies, but sadly Mac and Linux favorite Transmission does not. (If you're absolutely stuck with a client that doesn't support proxies, check the end of this article for some alternative solutions to the anonymity problem.)


How to Set Up BTGuard

BTGuard has a one-click install process, but we're going to show you how to do it the manual way, since it works in any BitTorrent client that supports SOCKS5 Proxy—not just the ones supported by BTGuard's installer. It'll also give you a better sense of what exactly BTGuard does, so if you run into problems, you'll have a better idea of how to fix it.

Step One: Sign Up for BTGuard

First, sign up for an account over at BTGuard.com. It'll just take a minute, and then you can get to configuring your client. Their BitTorrent proxy service costs $6.95 a month, but you can get discounts by buying multiple months at a time (up to a year's service for $59.95). Once you're done, you should receive an email telling you that BTGuard is ready to go.

Step Two: Configure Your Client

Next, open up your torrent client of choice and find the proxy settings within its preferences. In uTorrent, for example, this is under Preferences > Connection. Your client may have them in a different place (Google around to find out where), but no matter your client, your settings should look like this:

• Proxy Type: Socks v5
• Proxy Host: proxy.btguard.com
• Proxy Port: 1025
• Username: Your BTGuard username
• Password: Your BTGuard password

You'll also want to make sure you're using the proxy for hostname or tracker lookups as well as peer-to-peer connections, so check all boxes that say anything like that. You'll also want to disable connections or features that could compromise the proxy, so check all the boxes under uTorrent's "Proxy Privacy" section, or anything similar that your client may have. Hit Apply, exit the preferences, and restart your client. Your proxy should now be active.

Step Three: See If It's Working

To ensure that it's working, head over to CheckMyTorrentIP.com. This site can tell you what your IP address is, and compare it to the IP address of your torrent client, which will let you know whether your proxy is working correctly. To test it, hit the "Generate Torrent" button, and open the resulting torrent in your client. Then, go back to your browser and hit the Refresh button under the "Check IP" tab. If it's the same as your browser IP—which you'll see next to the Refresh button—then your proxy isn't working, and you'll want to double-check all of the above settings. If it shows a different IP address (often from another country like Germany or Canada), then BTGuard is successfully tunneling all your traffic for you.

Step Four (Optional): Enable Encryption

If you want extra security (or if you're trying to protect your connection from being throttled), you'll also want to encrypt all that traffic. Many clients have this feature built-in. In uTorrent, for example, just head to Preferences > BitTorrent and look for the "Protocol Encryption" section. Change your outgoing connection to Forced encryption, and uncheck the "Allow incoming legacy connections" box. From there, you should be good—your ISP shouldn't throttle your connection after this is enabled.

If your client doesn't support encryption, or you want a more powerful encryption behind your torrenting, BTGuard offers an encryption service as well. Just head to their Encryption page,download the software, and install it to C:\BTGUARD (this is very important; don't change the installation directory). Then, start the BTGuard Encryption program (accessible from the Start menu), and open up your BitTorrent client. Change your proxy server from proxy.btguard.com to 127.0.0.1, restart your client, and you're golden. Again, this isn't necessary if your client already supports encryption, but it is an extra layer of protection if you really want to keep everything private.

BitTorrent isn't the safe place it once was, and if you're going to use it to share and download files, we highly recommend getting some sort of protection from the services above so you can avoid DCMA notices and throttled speeds.
