Firewalls typically sit at the network edge and do not mediate internal traffic, thus anything on your local subnet will pass unabated unless a firewall is placed at each congregation point (ie - read switch - however even this is incomlete as any traffic internal to the switch will not encounter the firewall). The only complete solution is to have NAC in place that stipulates rulesets that must be met before access is granted to the network. This is where you can enforce your network policies. If you don't meet our standards, you don't get on.... I did some work on this about a year ago with a MAJOR network gear manufacturer's first step into this market - suffice it to say that the solution at that time was incomplete and convoluted. However in the interim I believe that the technology has improved sufficiently to be able to achieve your desired results. The major hurdle is to get the 'powers that be' to buy into the project and the underlying policies of network access control....<br><br>HTH,<br><br>-ejb<br><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;">----- Original Message ----<br>From: Mel Wade <mel@melwade.com><br>To: Support list for open source software in schools. <k12osn@redhat.com><br>Sent: Friday, April 20, 2007 7:55:47 AM<br>Subject: [K12OSN] OT: Stopping P2P sharing<br><br>We are looking for a solution to stop file sharing on student owned computers on our network.
