This is one of the core usecases of cloudflared (https://github.com/cloudflare/cloudflared)! Without having a static IP address or dynamic DNS, you can establish a connection between your machine in a private network with Cloudflare. And once a resource is on the Cloudflare network, you can pretty much do anything with it, including routing your visitors to that server and using the full Cloudflare stack including its CDN, firewalls, and Anti-Bot protections.
