I am switching my network from various carriers all to a Windstream MPLS network for all of my locations across the country. That being said, I will have the internet funneling through one main location so I can have one firewall in place to manage internet traffic from all locations, etc. I can setup Group Policies or adjust this hardware firewall that will be in place. The firewall model I will have will be a SonicWall NSA 3500. Since all traffic including VOIP will be going through this MPLS network, I want to start limiting personal activity a little more on the network. I know I can block sites like pandora.com, etc. individually, but is there a way that I can block all streaming radio stations for people that like to listen to local radio stations that stream? What about blocking video streaming such as youtube videos, etc.? What about if they are embedded videos in other websites? Basically, I need to limit non work related internet activity - No more facebook, pandora/streaming radio, etc. My network is made up of all Windows 7 client machines and a mix of Server 2003 and Server 2008 servers. I have more than enough bandwidth for normal business activity and probably for the streaming too but I want to make sure things don't get bogged down in any way.
