Is that airwave or the hardware controller?
Such option is not on the "instant" RAP109. My UI doesn't even look like that.
I see an option but it's GLOBAL and I want only one SSID VLAN (5) to isolate client traffic and not ALL SSID VLANs.
Here's how I have it
SSID1:VLAN10=Main unrestricted VLAN for internal
SSID2:VLAN3=Guests and mobile devices
SSID3:VLAN5=Client systems that need web only access for software update and antivirus definitions. <<I want THIS one to have client isolation]
I only want the client isolation on SSID:VLAN5 and NOT the other SSID:VLANs
