Reverse Proxy only allowing DynDNS-IPs as alternative to VPN? (alien.top)

Hi all,
I have the following challenges:
- I have friends and family that want to access my services
- But they cannot / don't want to install any VPN
- But I don't want to open my services to the complete internet

My idea: It's good enough, if they can access the services at home. They have internet provider with dynamic IP address. In the router, you easily set a DynDNS-Service.

So: Why not just have a rule, that only allows connections of the IP-addresses of the DynDNS-Domains. Of course, the proxy/firewall would recheck the DNS entry regulary.

Someone has tried such a setup? What solution are you using? Do you think it's similar secure as a VPN? (of course HTTPS connections only via Letsencypt cetificiate)

Haha, for my parents it's better to change an unvisible setting in the router, instead of placing a raspberry pi in their network or installing WireGuard on every device. They are paranoid with any software that must be installed :D
