In this playlist I cover Little Snitch. I go over how to install and set Little Snitch up, how to set up rules to monitor your network connections both inbound and outbound, and how to set up profiles for different networks.
In this playlist I give an overview of Plex Media Server. If you are looking to access your media (movies, music, photos, etc.) on any of your devices both inside and outside your network, Plex is a great solution.
