| 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. |

@bell.ca | This seems to work. It's 10:30pm and I'm pulling 450kb/s down. |

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. |

I haven't actually noticed any throttling on my account lately, is that still in effect? (London, ON). |

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. |

| throttling started over the last week in London ON for me on sympatico. was routinely pulling 500kb/s and all of a sudden went to 30kb/s.
thanks for the post, op. swapped to tcp 1723 and configured for encrypted connections - saw my dl's jump back to 500kb/s again. |

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.

any insight on how to change the ports with utorrent? or another xp compatible bittorrent client such as azureus?
in utorrent i did find the one option to change a port, but i dont think that covers dht or tracking.
thanks |

How do you do that with utorrent 1.7.7? |

| Unless uTorrent knew somehow that by using VPN TCP port to use the other ones on UDP.
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.

Je confirme : l'information est complètement fausse.
Même avec encryption et le port 1723, il n'y a aucun moyen de faire cesser le throttle. J'utilise UTorrent |

2 edits | I've forwarded the port 1723 for tcp/udp in my router
(wrt54gs running dd-wrt) disabled DHT altogether, and still no change in speed.
I'm running utorrent in xp sp3 connected via teksavvy on a 6000/800 line...
I'll try and do this in ubuntu with ktorrent and post if there's any change in result. |
