I don't trust to open my network to the internet though. So I've created a VPN to connect with my ubiquity network from mobile. Sadly, I can't share photos with other folks or allow my family to participate easily.
I'm a layman in terms of networking. I always wonder how people can sleep if they open their home network. In this case either by using QuickConnect or forward ports and access the machine through a custom domain secured by TLS. I mean that would be perfect but I just can't convince me to take that burden of maintaining that open door into my network.
I've read about creating sub networks with the power of ubiquiti (or any other router), but I will never trust anything I configure there either because I can't confirm it's secure.
So I'm stuck with Google Photos additionally to Synology Photos because of the convenience of sharing.
It does fit some workflows very well though, you just have to assess if your needs over the next few years fit their business intentions.
Nevertheless, Nextcloud keeps offering to sync my photos, and I think it also does that on Android.
I run a Mac VM on mine but via iscsi as the actual VM host hasn’t enough storage to hold my library.
There is only one significant issue that I found: Backing up large videos fails If I put the Syno behind Cloudflare. Because the photo backup app uploads it as one large HTTP form data and CF does not like it. So now I need to make do with basic firewalling at my place.
