What would be best practice in terms of creating a network to satisfy three separate businesses located in one building?
The building in question has three floors, each floor has 25 workstations and 2 printers.
The building itself has only one external IP address. My current plan is a backbone from router which has 4 interfaces going to a switch on each floor located in the server room on each floor, a firewall would separate the router and switch ensuring that each business cant access another businesses devices.
Could I assign each interface on the router as follows:
- Ground floor: 192.168.0.1
- First floor: 192.168.1.1
- Second floor: 192.168.2.1
Range for devices on ground floor: 192.168.0.10-35
Range for devices on first floor: 192.168.1.10-35
Range for devices on first floor: 192.168.2.10-35
Is this the correct way of going about this?
