Isolate Specific Application Connection Only

[floydque]

Is there a way to block all internet traffic except for a specific application only?

I would like to deploy an open Wi-Fi but anyone who connects to that wi-fi (usually employees) will be only able to connect to Microsoft Teams and nothing else.

Thanks

What comes to my mind would be to remove any allow rules. Then look here MS Info on Teams. Make the appropriate aliases from the info there, what needs to be open for TEAMS, then create allow rules.
