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?

You can use any domain you like. I personally have an actual domain that I only use inside my network. This way I can get SSL certs from Let's Encrypt using the DNS challenge which doesn't require any ports being opened. You can use self signed certs but I would strongly suggest using certs from the likes of Let's Encrypt.
