Which ports to block for P2P/Bittorrent from my router

post #1 of 16
Thread Starter 
Okay soooo,

Until yesterday I had all of the bFbc2 bandwidth needed. Well my roommate just got himself a new laptop and now he's downloading music through Bittorrent. I told him how to download(big mistake) but, I told him not to download when I was home from these hours. Well guess what? He is and now he's taking up the bandwidth.

Has anybody had this same problem? If so what ports shall I block?

Bittorrent uses port 6881-6889 and 6969. If your room mate uses another program it will be another ports.

If you want to get more strict you could block all these ports.

He may have also set a random incoming connections port. So, you need to find that out

The best bet will to be block all traffic and allow only selected traffic to go out of the router.

HTTP: 80 (TCP/UDP) 8008 8090 8080 (All TCP.)
DNS: 53 (TCP/UDP)
HTTPS: 443 (TCP)
DHCP: 67/68 UDP and 647 TCP

Only a few listed and this is for basic communications. If you want programs that relay on the internet they wouldn't work.

LOL, I used to have a roommate doing the same thing. I had him trained like a dog, all I had to do was yell "Hey you downloading again?". Same reply everytime "uh, uh...no". Then my connection would magically speed up.

Don't ask me how it worked, I just know it worked.

hm, if he a good networking dude then he can use port 80 for download... the best way is, block with a good router... like "DrayTek" u can choose "block torrent" so, the header will be scanned and the router block the connection... this is the best way... ;-)

Don't block, restrict using the QOS engine in your Router. Set it up so he actually only gets a fraction of your bandwidth, during whatever times you want.

Blocking ports all together on someone who prolly helps pay that bill aint cool.

use qos (may need to put dd-wrt on your router if it supports it).

then set bittorrent traffic to "bulk" priority and he'll get all the bandwidth you don't use, and neither one of you will experience problems.

Security-wise, an implicit-deny policy is the best way to go but for a home user it's overkill.

Prioritizing traffic using your router's QoS engine is solution that is both effective and is as least restrictive to other users as possible.
At long last...

Since he is downloading ... the internet is in his name, right?
