I couldn’t get my head around DDNS when I started out, so I ended up renting a dirt cheap VPS and running a wireguard tunnel from my homeserver. I think I pay ~$3 a month for the VPS, where I also run the reverse proxy for my services (Caddy).

Cons: I’m not completely self sufficient Pros: My machine is not exposed directly to the net, and it was laughably simple to set up.
