An update on my personal project, I have setup my own VPN using the Netgear FVS318-Gv2 across three (3) locations. Using the HDHomeRun Prime at my location in New York, I am able to access my cable subscription via that network remotely from the other two locations. With Channels app for iOS (Paid) and testing the app for Apple TV (Beta), I’m successfully watching my channels.
If there are any questions about my setup, let me know.
