>- Not every home internet service gets a static IPv4 address so folks have to handle DynDNS

For anyone who has only this specific problem out of your list, one solution is to get an HE tunnel. It's what I do.

If my ISP ever gets off its ass and implements IPv6 like it promised three years ago, I'll consider using that directly, though its current indication is that the IPv6 addresses will be dynamic for non-business customers which defeats the purpose.

I have gigabit fiber and it's IPv4 only. My ISP blocks incoming ICMP messages so I can't set up a HE tunnel. I used to use Route48, but they shuttered due to abuse, so I don't know what to do anymore.

A non-free solution would be to have a VPS or a cloud VM act as the public endpoint + wireguard server.
