| How to defeat the throttle The following article from the CRTC website shows how to defeat the throttle:
»www.crtc.gc.ca/public/partvii/20···3769.PDF
===
A more fundamental flaw in the Traffic Management Solution championed by Bell Canada is revealed when one considers exactly how they dealt with the
problem of encrypted traffic. Forced to associate VPN connections with a specific
port, they make it trivial for users of peer-to-peer applications to bypass the DPI.
A user wishing to download content via BitTorrent needs only to configure their
client to use the VPN TCP port to transfer content, associate any remaining UDP
ports with the standard IPSec Authentication and Encapsulating UDP ports, and
strictly apply protocol encryption to all incoming connections.
===
Set your bittorrent port to TCP/1723, and put any DHT or tracking on UDP/500, UDP/50, UDP/51. | |

| This certainly works, Bell began throttling me today. I'll switch to teksavvy or acanac at the end of the month, this should see me through.
If they ever close this loophole, people might want to look at xerobank's anonymous VPN services. I know i'll be using it if bill c-61 goes through. | |

| Re: How to defeat the throttle Actually, if you RTA, you find that this isn't a loop hole; it's a direct result of how they throttle, and that they can't secure VPN traffic because it's encrypted.

they do throttle every company that are using there lines | |

1 edit | Setting my ports to 1723 has no visible effect, i suspect that Bells DPI has at least a 60 second delay.
I've also reset my modem, router and pc a few times just to make sure that the throttle is likely off...
This is also downloading from private trackers that normally hook me up with xbox360 games at 600K/s.
:-(
I'll fuck with it some more and write more later. | |

I think you may be able to make the changes under the advance options in utorrent. Im not home now so I can't check, but thats the only place that comes to mind.

2 edits | Hi,
We have posted a guide on a possible method to overcome the Bell Canada throttle. It is available here:
»pervices.com/docs/throttling_tech_brief.pdf
It include sample configurations for uTorrent and KTorrent.
We would be interested if this technique works for you. Note that it may take a while to work, as it is possible that the DPI device 'remembers' if you use BitTorrent.
So far, we have used this method to use peer-to-peer communication over a third party ISP network (Tek Savvy). We do not know if this will work for Sympatico customers.
If this technique works for you, we would very much appreciate you telling us your ISP name, so we can learn more about how Bell Canada throttles traffic.
Please note that we use Linux exclusively, so we may not be the best source for uTorrent questions (uTorrent is a windows client).
Warm Regards,
Victor Wollesen

Followed your instructions for utorrent... didn't work until I rebooted the DSL modem, resetting the connection...a standard Bell Sympatico connection. WOOO!

Switch listen port to 1723.
And go to Advanced>Connection and beside protocol encryption put "always".
Of course you'll have to set up your ports for whatever client you use. Instructions on how to do so @ www.portforward.com
Thanks guys. | |

| Re: How to defeat the throttle My only concern with having forced encryption on is that you can only connect and transfer to other people who also have encryption enabled. I have found before when doing that that it is more difficult to get transfers going at a decent speed.
But I guess nowadays more and more people are using encryption for torrent transfers so maybe this will become less of an issue.

2 edits | After failing in utorrent/xp...
I've rebooted into ubuntu hardy and installed ktorrent and set it up using port 1723.
I can confirm going from 25K/s in xp to running at full line speeed in ubuntu. It didn't work initally, so i power cycled my 6520 and was up to full speed within 45 seconds.
Thanks perverts! You're the shit!
**strangely enough, i've just rebooted back into xp and now it seems to run once again at full speed.
I haven't changed anything in my settings, it just seems to be working now without any further intervention other than it running port 1723 in utorrent.
oh yeah, and I submitted this to Digg... | |

| Ça ne fonctionne absolument pas pour moi.
J'ai suivi attentivement les instructions. J'utilisais déjà l'encryption avant les modifications du document et ma vitesse était d'environ 80 kb/s. Maintenant, elle n'est plus que de 40 kb/s.
Même le numéro de port dans le PDF indique 1753 mais partout ailleurs, c'est écris 1723. Une autre erreur bizarre ?
Bon, j'ai essayé les 2 ports, j'ai éteint/rallumé le modem (je n'ai pas de routeur). La vitesse n'augmente pas.
************************************************************
Absolutely doesn't work for me.
I followed instructions very carefully. I was using encrpytion prior to these modifications and my speed was about 80 kb/s and now, after that, it's down to 40 kb/s max.
Even the port number in the pdf indicates 1753 but in the news front page, it says 1723. Some weird mistakes ?
Anyway, I tried both ports and tried with reset modem (I don't have a router). The speed won't increase. | |

| Dear BellACancer,
We've added some notes to our initial document speculating on why this works for some people. It is available at the same link as the original.
Could you please find out if you have unthrottled VPN access?
Specifically, see if, when connecting through a VPN, you are throttled. If you are, please let us know.

| so yeah yesterday this method didn't work for me, but a power cycle of the modem seems to have done the trick. its 7pm in Toronto right now, and i was getting 200kB/s+ down from a private tracker. normally this particular torrent would max out my connection but i think with the forced encryption, it must cut out a lot of the available peers? anyhow a lot better then 20-60kB/s
cheers | |
|
Anonymuzz
@bell.ca | It appears as if this temporarily works (for upwards to a few hours) before I'm throttled again. Restarting the modem seems to remedy this momentarily, but it appears as if the throttling has started back up again as of this post. | |

| yeah this technique seemed to work hitting 200kb/s for a bit, but watching the speed tab in utorrent i can clearly see that around 9pm to 1am i was capped at around 20kB/s down and between 1 and 2am it was 40kB/s and for the rest of the night i never broke 200kB/s, and honestly i probably should have hit 450kB/s at least a few times with these torrents and my connection. bell u suck!!! | |

| Didn't work for me (DD-WRT on the router, ST516 modem). I reset the modem & started downloading Ubuntu with 300+ peers available, got the usual throttled 25-30K download speed. Tried again this morning & was downloading at full speed. In addition, utorrent now says that my ports are closed, even though nothing is reported in router log and in Outpost software firewall log. I did change my port forwarding settings in the router & firewall rules, but utorrent reports that 1723 is closed. | |
