App isnt a VLAN it is just a single server connected to a interface on the
router
the switch is connected to another interface on the router via a trunk, this
switch has 2 vlans
STAFF
STUDENT
i dont want staff and student to be able to communicate with eachother
However i want them both to be able to access application which is a single
server connected to another interface on the router
