I'm hoping the answer is no... as I'm dreaming up a shared internet
facility trying to keep student users roughly isolated on a simple
switch (no VLAN support).

The small community centre for which I'm "IT manager" (who I manage
other than myself I'll leave as an exercise) has a Cisco small-business
router at the heart of the network. It supports multiple VLANs and in
the definition of each there's a tick box which enables or disables the
ability for any host on that VLAN to see any other. With that facility
enabled all that a visitor's phone or laptop, connected casually by
wifi, can see is the router itself for the purpose of connecting to the

Would that facility meet your need?
