Hey guys, living at university with a few roomates and we'll all on a DSL Connection via a 3com Router. Now there are 4 computers connected and I know they all just leave Imesh and Kazaa on and suck up my bandwidth, especially when they are uploading to people. I guess what I was thinking is that I could block the upload ports on the rouyer for the 4 thus saving precious bandwidth. Anyone know what ports I would have to close in order to acheive this?
