Caught this thread and wanted to mention a few things…
First up, please give HousePanel by @kewashi a whirl. It's awesome. There are several ways to then connect to HousePanel remotely – either by VPN or a few other methods.

While I do have VPN access enabled to my home, I only use this for troubleshooting and admin type work on HE. At the moment, I use a standard Hubitat style dashboard for "friendly" remote access to turn on the lights as I am walking home from the car or check status. There is a cloud link available for every dashboard page. That link, once saved to the home screen on my iOS devices, has been enough for my remote access needs.
But to pursue remote access aka "access through the internet" using VPN seems clunky. It never would pass the WAF/SAF test either. Soon I am going to experiment with Dataplicity to see if it can deliver on the easy remote portal promise. Anyone else wants to give this a spin please report back! I think there is a developer API so perhaps someday @kewashi with the help of this community will be able to integrate it or something similar.
In the meantime, happy Hubitating!
