I want to know if it's possible to block filesharing programs from the Apple Airport Extreme? My brother and I share the same internet connection and he spends his days downloading movies and music from various filesharing sites. When i told him that downloading movies illegally was a crime that I could get in serious trouble for he seemed to be completely surprised that doing so is wrong. Simply talking to him has done nothing cause he has a teflon attitude and has figured that he would not be the one to get in trouble, I will. It also makes my connection extremely slow all day long. Is there a way either from the router or wherever to shutdown his ability to continue using filesharing? I thought about just locking the network so he can't use it but he pays for 50% of it's cost. Thanks for your help.
