Hi all, I have a question concerning a network job. My customer is in a small office building with a cable internet connection. There are 4 different companys in this building. They are all gonna share the cable internet connection via 4-port router and a 8 port switch. For a total of 7 pc's. Currently, only 4 of the PC's are gonna be networked. My question is: How is the best way to keep the other computers from accessing the 4 computers that are networked?
Desktop1-no network/Internet connection
Desktop4-no network/Internet connection
