I can recommend cockpit for managing the firewall

I was successful in installing and using caddy directly on my host instead of podman (docker).

Edit: someone doesn’t like that I succeeded at it …

I just update. If it breaks, I read the notes. Probably the wrong way but it worked. And I use it for a long time. To me, it was never that unstable. And since a couple of months it’s very stable. Backup first.

Sounds like a good solution as well

I run nextcloud on my machine. If there’s a crack, there would be one in their hosted instance as well. There’s nothing really I can do about security of it.

Ipv64.net is an alternative, just in case you want to switch some day

I had problems with duckdns as well. Never had problems with ipv64

Thanks! I use wake on lan with rtcwake to boot at a certain time. I also found an app via which I can boot the server via wake on lan. But it would be nice if it could wake up just by requesting the service

Anything would be fine I guess. Try fedora server. It ships with a gui (cockpit) for basic management tasks. Maybe it suits you
