How to host vaultwarden internally (feddit.org)

I want to host a Vaultwarden (or Bitwarden if necessary) instance, but it keeps asking for a domain and a SSL certificate. I dont own a domain and dont want to enable port forwarding on my router to expose it to the outside.

Is it possible to host a instance only internally and access it via the IP or a domain set on my local DNS? How about SSL is it possible and/or necessary?

Good question. You could set a domain name point to your IP in your router. That has different names, might be hosts-file or just buried somewhere in the DNS settings of the router. Or machinename.local or .lan works. That should give you some internal domain name, valid inside of your network / wifi.

Getting proper certificates without exposing anything is tricky. If that's really needed: You'd either generate a self-signed certificate manually and import that onto your devices. Or you need to do some trickery with letsencrypt's DNS challenge. That's not super easy, but possible: https://m.youtube.com/watch?v=qlcVx-k-02E

I don't use Bitwarden. There might be another specific solution to do it.
