Proxying the whole computer

Hello!

I have a quota limit on my computer for daily internet usage. This limit can be bybassed on browser use by using a certain local proxy server. The quota limitation has not been bothering me as of late, since I need to download some large packages.

Is there any possibility to either change the uTorrent program to use this HTTP proxy server (I tried to put the proxy on from the advanced settings area but the download didn't begin for some reason), or download a program that would channel all the internet traffic through this proxy?

Help much appreciated.
 
I'm on a quota because the ISP wants to limit the daily data transfer from it's clients. They have stated that using proxies is allowed and even advisable even though it bypasses the quota limit. Though using the proxy for other uses than normal web surfing might be stretching the rules a little.
 
Well it's a student network that comes with the rent, so changing would be hard if not impossible. I don't complain though, the quota is some 6 gigabytes and it's a 100mb connection speed with quite a low price.

I would just be happy if I would, in case of emergency, be able to bypass the quota. Setting proxy on from the settings didn't work. Perhaps they have made it impossible to use torrent software through the proxy or I am doing something wrong.
 
They may well be blocking the torrents on purpose. You could get round it using SSL encryption on torrents. This uses port 443 and appears to the proxy as a secure HTTP connection but carries the torrent traffic in disguise.
Though some firewalls can SSL decrypt and see the torrent headers anyway and block it still. Universities do generally have the facilities to do this more than most.
But i really wouldn't grumble and ludicrously fast downloads with a 6GB daily limit. That equates to a monthly cap of 180GB which aint bad if you're paying neanuts for it.

Traffic won't magically travel over port 443 if protocol encryption is used. The port needs to be set in the client configuration.

In general networking that is true, but most torrent clients do redirect traffic over 443 by default when you turn on SSL and some allow you to manually override it if you so wish.

uTorrent in this case defintely does support SSL and 443 is the default port it uses. It also supports a proprietry feature to uTorrent and Azureus for avoiding throttling and blocking called PE (Protocol Encryption).

uTorrent doesn't use port 443 by default.

uTorrent with forced encryption and port randomisation for incoming connections.
 
Well thats not what the documentation on the utorrent site says. It specifically says it uses 443 for SSL by default but the port is user configurable. If that's a default install you've pasted up then the site is quite misleading.
I don't use uTorrent so I was kinda relying on that info being correct.
