When the mirror will then always repond to me with ' The only thing that exceeds your brilliance is your beauty! '

Hey Marce,

Thank you for replying but are you aware if PSN utilizes Internet for any services?

I'm only sure about Intune MDM, but most probably any cloud service you may have subscribed to, such as sms gateways, needs internet access directly from PSNs.

Hello Marcelo,

Thank you for sharing the resources. That was helpful.

So to confirm based on the inter node communication diagram of ISE, ISE PSN requires Internet ONLY for sending SMS and Email Notifications.

Thanks again.
