This should be relatively simple for even a basic firewall
as long as it has multiple interfaces
users A B C in zone 'Wireless' connect to interface fe 2/0 (port 2)
servers are in zone 'Trust' connected to interface fe3/0 (port 3)
then the communication between zones is set to ALL- PERMIT - bi-directional
start there then you can always make the rules more restrictive
these days most decent firewalls also act as Switches and routers at some level
