That’s basically what I do right now except I do have a domain and my ISP doesn’t restrict inbound ports like 443 so it works fine.
Just trying to sort out if I want the headache of a VPS if I don’t need it (costs, maintenance, point of failure, etc).
They used to have poor band support in north America, though that seems better now on the 5. I’m still salty about the removal of the headohone jack though.
