I have an unmanaged switch that I want to add three RJ45 sockets to. While the rest of the devices on the network are connected to each other I want to restrict access to the network to users on these 3 ports but allow them to use the Internet. Is there a device that I can use to do this or can it be configured via software?

Moderators please move this thread to Networks as I did not originally see that category and now don't know that I can move it myself
