Network administrator is spying

My family has a small network of about 7 nodes set up at our house. My brother is the one that set it up. Everything was going well until a couple of weeks ago he got the idea to start blocking us for using limewire, torrents, etc. I need to know if there is a way that I can stop him from seeing what programs are accessing the net from individual computers. Any help that you can give us would be helpful. Thanks

 

Where can I find one of these anonymizer programs?

 

Time for a family meeting. If you both still live with mom and dad, and the Rents are footing the bill for highspeed, they should be the ones maintaining what is being used,

If it is your brother's place, and he pays the bill for high speed, he can dictate the use on his network. I am guessing that your brother is upset that he cannot get exclusive use of the connection.
