Okay, we're all threading about RIAA's FUD sue 'em all, bla-bla-blah. But here's a problem. My computer-challenged compadre got DSL connection. I got him a D-Link DI-614+ to block Kazaa from his 2 minor boys (both honor students at magnet school, has laptop provided by the school). I already blocked the outgoing TCP port 1200 to 1290 but still they can download MP3 because Kazaa use any open TCP port including port 80. Anyone knows how to effectively block Kazaa from a hardware router?
