Well, after a few years of using IPTV service, I found that Frontier is now actively blocking my IPTV servers. I confirmed with the IPTV provider that they haven't blacklisted my IP or anything. I called up Frontier and they falsely said 'Frontier' doesn't block anything. Lies. The servers work fine through expressVPN. Ridiculous. Has anyone else had same experience with Frontier fios FL?
I consider a VPN to be necessary, especially when using IPTV. It is what it is, as they say. A VPN is not sufficient for overall security and privacy. But it does keep your ISP from snooping.
