Xentrk, Good to see new info on this thread, earlier posts date to last August. Hope to work with your info on our PfSense box. We've had recent issues with our AFTV devices and Amazon streaming in general. (Netflix and Amazon's Fire support has always been abysmal). We use TG's VPN which has always served us well, and our 2017 AFTV and last year's Fire stick once performed as well as our other devices running over the AC3200 then our AC86U. The AFTV became too balky a couple of months ago soI disconnected them, though the AFTV isn't to blame. What I've read lead me to believe it has more do with Amazon discouraging those using non-Fire FW and who don't allow the units to update. Our devices used original/updated FW and always routed over VPN, not the ISP's service.
Without straying too far, I talk with a high-level contact at the ISP's technical division every few months re streaming, data privacy and other issues. Regarding our own AFTV issues, he mentioned that they receive very few complaints regarding Netflix streaming, as NF provides their content servers, and they receive countless gripes from customers with AFTV or who stream Amazon video on other devices. The ISP always refers those customers to Amazon's support. The ISP was a cable company first, an ISP second and last year began providing phone service in some areas. They're hoping to make up losses from cord-cutters when the larger cable companies begin their own streaming content, competing directly with NF and Amazon. The fellow was less concerned with the upcoming roll-out of verifiable caller ID to ISP and phone customers, to halt robo-calls, as opposed to giving content providers more precise control and leverage over devices, much as they now enforce against VPNs. While it won't affect our streaming, it will have an impact on which devices are acceptable or authorized to receive tiers of content or speed, and huge problems for VPNs. Good luck to us all, Cheers.
