CalDAV Server Without Exposing Server?
CalDAV Server Without Exposing Server?
I self-host a couple of services, but I haven’t exposed anything outside my home network. I want to self-host my calendar, but not sure if I can do it without exposing it. Any recommendations on the best way to go about this? For those who do self-host a calendar service, how do you keep it secure?

mTLS with a reverse proxy!
What caldav clients supports that?
I’d recommend the Tailscale style approach. MTLS is a pain imo without infrastructure and especially on the app layers
Tailscale is simpler but when you're accessing from devices behind VPNs like I do mTLS is a lifesaver.
I use DAVx⁵ for caldav (supports mTLS)
I find mTLS cool too :P
In terms of being a pain it's not that bad with nginx in my opinion. I can just build my own certificate for each service I expose or you use a common one, giving read only access to the key for my nginx containers and in two lines in the .conf it's sorted.
This is the first time I’ve heard of mTLS. Sounds interesting, any tutorial recs?
Not any in particular but mTLS is essentially just a reverse proxy (like nginx) asking a client for a certificate to be able to access the service behind it.
There are quite a few guides out there, so choose one for your reverse proxy of choice!
