Hi I'm trying to sketch a computer network. The network include about 50 computers for employees, 20 computers for tech office, a few network printers, a wifi area and every employee has an ipPhone.
this is the sketch I made, but I'm not sure about few things:
Is it correct to link the ip phones to the pc or should they be connected directly to a switch?
Is the dmz placed in a correct way? It should just keep a decent security level the mail server.
Generally speaking, is it a good configuration for the network or should I change something? I'm not sure this is the right forum where to ask, if not, can you please suggest me where to ask?
