How can I prevent my roommates from using torrents? If necessary, I’m willing to buy a router that makes this easy.
So how did you go about this? Did you find any of the above suggestions helpful?
An easy way
Open separate user accounts.
You have "administrator rights" and assign "Limited" to your flat mate.
Effectively placing the firewall under your control.
you can set your routers to use OpenDNS and just use the blocklist for P2P/Filesharing.
Set up a hardware router. try with ClarkConnect - it has an a option for detecting/blocking p2p traffic
you need one low end machine and 2 network cards in it /
Click "Start" and select "Control Panel." In the "Control Panel," select "Windows Firewall."
On the left side of the window, click "Allow a program or feature through Windows Firewall." A list of allowed programs will appear.
Click "Change Settings" and look for any torrent clients in the list. Remove the check mark from the boxes next to the torrent clients. If your torrent client doesn't appear in the list, click "Allow another program."
Select your torrent client from the list on the following screen. If it still does not appear, click "Browse" and from the drop-down menu select "My Computer" then double click "C:" and go to "Program Files" and locate the torrent client in the list. Double click on the torrent client once you find it.
Click "Add." Remove the check mark from all the boxes next to the torrent client(s) you added. Click "OK" to save these settings.
The OpenDNS option is the easiest one I suppose.
