Is it possible to keep Nextcloud trapped behind a VPN but allow Nextcloud users to sync calendars items from their devices to Nextcloud (and vice versa, if the event was created directly in Nextcloud) outside of the VPN? In particular, is it possible to expose an endpoint that allows 2-way sync directly against Nextcloud’s SabreDAV server?
The endgame is to use Nextcloud’s calendar and contacts as instead of Radicale or something else. Nextcloud is a resource hog so if I can do it here I don’t want a separate service for it… But it’s looking like Nextcloud can’t do it. I’m excited to be proven wrong!
I’m really hoping this is a layer 8 issue as I haven’t seen anything/anyone say this can’t work and I’m fairly certain SabreDAV can do this (though I could be wrong). I could stand up something in the DMZ/cloud but that would be in addition to hosting Nextcloud in the lab (and the installation seems really fragile- I don’t want to mess with that again), and that seems far less optimal than “publish a service endpoint and call it a day”.
Does anyone have guidance they can offer? What keywords should I search for? Is this not a feature of Nextcloud?
Thanks in advance!
