[HELP] Protecting home IP (privacy reasons) with an ISP that only offers dynamic IP adresses (lemmy.ml)

I have a self hosted server running yunohost that I use for a few services for my own use all of which require login to use so they're safe enough.

However I'm increasingly uncomfortable with the fact that anyone can discover my home IP via my domain name. Especially if I decided to install something like Lemmy or Mastodon.

Yunohost installs dyndns as part of it's setup but, aside from buying a fixed IP from a VPN provider that allows incoming connections I'm not sure what other options I have

I can't change very much on the modem router either. I can forward ports but that's about it.

I can add and manage new domains if necessary.

Any and all ideas welcome but, as you can guess from the fact I'm using yunohost, my networking knowledge is limited so please eli5 :)

You have several options these days:

Use cloudflare in DNS proxy mode and run a dynamic DNS updater so cloudflare always point to your correct IP address. By using cloudflare DNS in proxy mode, your real IP address will be hidden because all traffics will be routed via cloudflare servers first. The disadvantage is it only works for http/https service. If you need to route other service/port (e.g. ssh) you'll need to use cloudflare tunnel
Rent a small vps and use it as a bastion server. Add your home server and the vps server into tailscale or zerotier network, and then configure it to route traffics to your home server. I personally use this method because it gives me full control and flexibility over using cloudflare, but it does harder to setup.
