! ===== WAN uplink VLAN =====
! Port 48 connects to an ethernet hotspot or venue uplink. The switch
! acts as a DHCP client here - the upstream device assigns it one IP
! address. NAT (masquerade) then hides ALL internal traffic behind that
! single IP, so the upstream only ever sees one device.

! ===== Internet-only VLAN =====
! Ports 44-47. Devices here get internet access but are completely
! blocked from reaching any FMS or team network addresses.

! ===== NAT (PAT / masquerade) =====

! device. To the outside world, everything looks like one machine.
