basically we use TV to provide our users meeting functions. Therefor they need access to the internet. So far that works. We don't want the users' computer being reachable externally by anyone. So we disabled incoming access generally (Options - Advanced - Access Control: Deny incoming remote control sessions + General - Incoming LAN connections: disabled ).
Now we would like to use TV for internal support purposes only. Setting "Incoming LAN connections" to "accept exclusively" would disable Internet access and Meetings as well. That does not seem an option. Setting "Incoming LAN connections" to "accept" enables support sessions from local network, but "incoming remote control sessions" have to be enabled and that would allow potential access from externally.
