I’ve run Nextcloud several ways, the smoothest and easiest being the official image by Hanssen IT. Run that in a VM and use their setup/update scripts to do all the hard work. I highly recommend.

I’m on Vodafone here in the UK (CityFibre), and they let me use my own firewall to the ONT, and give me a static IP for no extra cost. It’s a PPPoE connection with a VLAN id. With work recently I’m using about 5-6TB monthly data. I should count my blessings for their service given all I’ve read here!

I had issues with connectivity around 2020 and they wouldn’t engage with any help troubleshooting it unless I used their provided router, which was a pita, but a few days of speed tests and they escalated it and fixed it.

just schedule an email to send at a later date/time, then if you don’t login to cancel it, off it goes.

Yes, as @Darkassassin07@lemmy.ca says, just create a new user for each event you want to share photos about: ‘BeachBBQ’, ‘WeekendStay-July’ etc, then bind those user accounts to whatever folders you want to have the photos in and set the user restrictions to upload, share, but not delete for example.

I also use various FileBrowser instances, with a different subdomain pointing to them, also as a way to filter out usage as well. collegefriends.mydomain.com could take you to a FileBrowser instance that only has access to photos from a certain friend group. Not sure how useful that would be to you, but it’s another way of controlling the data flow.
