Logs explanation (Audit TV Connections)

Hi all,

we need to have some way to trace connections with TV in our company.

I find a solution with the logfile "incoming_connections.txt", that's perfectly  useful for our needs, except i cannot find if connection is done by LAN or by Teamviewer ID (outside).

I tried to check on the other logfile, but it's very cryptic: are there anyone know how to check if connection is made from internal LAN or external?
