What ports to block P2P downloading?

post #1 of 19
Thread Starter 
Ok so my brother is CONSTANTLY torrenting random things and I no matter what I do he will not stop and it makes the internet go VERY slow, so slow it even takes google around twenty seconds to load. My question is what ports must I block to disable his torrenting? if it doesn't involve ports what can I do?

Do you have any sort of DNS server set up? I would set up a forward lookup zone for his favorite sites and leave them with no host, aka when he goes to a torrent site it times out. Depending on how good he is he might get past it. If you cant do that point your router to opendns it will filter most torrent sites but it may block your favorite sites too if you know what I mean smile.gif

Setup the Qos engine in your router. You can preset up/ down traffic to specific local IP.

Edit: He may be using random ports for torrenting. This is usually the best option. Give him a decent but fair % of your bandwith. He'll prolly never tell the difference.

You may need to talk to me in noob lol.

My router options show something called Dynamic DNS, is this what you are talking about? what is/how do I do open dns?

Instead of blocking torrents explicitly why not taking an 'implicit deny' approach?

Basically block all traffic to his MAC except port 80 (web) and any other ports you are comfortable with him having opened.

I'd suggest setting up Quality of Service (QoS) on your router (if it has that function) to his ip address, limiting his bandwidth. Other then that, if he doesn't know much about it, you can limit the bandwidth in the torrent program for example utorrent, you can have a set bandwidth for both upload and download. Now he may notice that one so I'd try QoS first.

A step by step guide will differ depending on your router, the firmware it is running, etc.

Take a look in your router config options at QoS. You are basically trying to see what options you have to limit traffic to a specific IP or MAC address. If your brother has a static IP (it stays the same, always) you can use the IP, otherwise you will need to use the MAC address (a serial number of sorts for his specific network card). The only way to grab the MAC that I know of is to be on his computer, but I'm sure some clever person here knows how to do it remotely.

You can usually access your router by typing its IP address into a browser window (192.168.1.1 in my case, or perhaps 192.168.0.1) and entering the admin password when prompted. You will probably need to use a computer connected by WIRE.

You should first see if it makes sense to you the way they set up, and if not, post back.
