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.
