What I'm trying to do here is take an office of 40 ports and make it so none of them can talk to each other on the network. They each still need to be able to access the internet but cannot be allowed to tansmit data to, or access each other.
Can this be accomplished with a Catalyst 2960 Switch and a Comcast business class Gateway IP (Modem)? Or would I need a CORE switch or router in between??
