I moved, and now my new router has no ipv4. I can expose the host with ipv6. After opening a port and exposing the host, the host is fully exposed and all ports are open. It’ss weird. Vodafone calls ut host exposure, I can select a specific port and all ports are open.

How do you guys corcumvent that issue? Is this the infamous cgnat problem or is this why many people use a cloudflare tunnel? I just want to reach my nextcloud and immich with a normal domain.
