I have a Linksys Wireless-G broadband wireless router (WRT54GS) and have a workgroup LAN setup at home. Three PC's are XP Pro and one is Windows 2000. The three XP Pro workstations are my kid's computers.
This router has a parental controls feature built into it and I can prevent my kids from surfing "problem sites." But, this router will not block Kazaa or P2P filesharing sites so really, the parental controls feature is useless.
From an administrative standpoint and at the router level, how can I block P2P filesharing programs and at the same time allow them to access the LAN and browse the internet? Also, I would like to have some sort of KILL command I can submit from my workstation to theirs. Is there such a program? It would be nice if I could Jam their PC from or something when I see the Internet traffic pegging out.
