I'm looking to set up a network drive for my company so we can share documents. We rent a room within an office so a file server would not be practical. There will also be remote users that would need to access the drive. I have been looking at getting a NAS device as an alternative to a server - would this be the best option? As we are using the internet provided through our landlords - would we need to get their permission to allow our remote users to access the drive (would their firewall prevent them from accessing it)? If we do go down this route - would we also need to purchase a network switch?
