    Hi,

    I manage a wireless LAN and recently torrents have been by a few users causing great problems in speed and ping times for the rest of the users.

    I have a router that will block certain port ranges - what ranges should I block just to prohibit p2p / torrents?

    Also are there any programs that will let me track web usage of each ip address on the network (speeds, gb's downloaded etc.)? I'm using a standard wireless belkin router.


    Many thanks in advance,

    72oo

    6890-6899 or 6990-6999 are the the ports used by p2p programs, but MANY other applications use this range too. It is high inadvisable to do this.

    It's a bit hard to block P2P and Torrents because most applications allow the user to choose a random port or choose their own port

    Setup a Linux router with L7 Filter.

    Thanks for the info.

    Do I have to buy specific hardware for that or can I install it over my current router?

    You'll need a PC computer with 2 compatible network cards.

    Might want to give this a look.

    @ WackyT:

    Thanks for the link, very interesting stuff.

    My situation is slightly different.

    The network is exclusively used by laptops (including me) and I haven't a desktop at this location that I can use. I've heard about blocking certain ports 6800-6900 or something like that. I might have to go with this given the lack of a desktop.
