I understand the processes required but if you or anyone here knows, what would be the least expensive / most sustainable way to set up a personal VPN & pihole plus a simple website hosted on a server? I already run a small server at home for NAS / HomeAssistant / PiHole, etc., but I would like to be able to access it anywhere and enjoy the benefits of ad blocking and personal media access on my phone outside of my home network, but I don't want to spend $25+/month for crap tier single 9 service, and at the same time, I don't need flawless service with five 9 uptime guarantees at any price, either. I'm guessing that I would need a VPS provider that allows SSH access to some flavor of linux server with a static IP or at least a domain name. Am I on the money with this, or is there something that I didn't consider? If I am, would you still recommend pair.com or is there a VPS provider that might be a better fit?
