Hoppy
hoppy.network
Hoppy provides a unique public IPv4 and IPv6 address to each of your devices, allowing connectivity without limitations. If you are behind a restrictive ISP, constantly on the move, or self-hosting services, Hoppy is for you. All major platforms are supported.

A bit pricey and I haven’t tried it myself, but it seems like a good option for self-hosting on overly-restrictive ISPs.
