WAC510 client isolation not isolating clients

[just-answers]

I am running in AP mode with two SSIDs ("main" and "guest"). I've enabled  "Client isolation" on the guest SSID network but I'm still able to ping devices on the main SSID which I thought should not be possible as per the documentation. Is there some other setting I'm missing?

Setup details:

• ASUS as main router.
• WAC510 as AP connected to the ASUS with DHCP client is enabled
• Firmware: V9.5.3.2

Hi @just-answers 

Could you please provide the following additional info?

1. Any VLAN SSID configured?
2. If yes, is inter-vlan enabled in the Router ?
3. If possible, please share the Detailed logs via PM.

Thanks,

Raghu

Beyond of the ping, is there any other communication by IP or UDP possible?

Strangely, after rebooting WAC510 it is working as expected and I cannot ping between the SSIDs anymore. Maybe that's needed after enabling isolation?  I'll keep checking to see if it fails again.
