This thread has turned away from VPN but an awful lot of routers have OpenVPN support. If you have a mac you can buy the server program for $20 and run a VPN, also for mac is a program called VPNConfigurator or something like that.
I have a hardware firewall appliance (pfSense) that has a ridiculously easy implementation of OpenVPN. I run my HA behind the VPN and while I guess I’m limiting myself with some of the cool Alexa actions I personally prefer having just one port open on my firewall and then i can access all my servers, and HA, etc.
