Hello, I'm wanting to build a small server and self host a couple services. However, I'm not really sure if what I'm trying to do will be possible and/or simple enough for a beginner.

I want to host Nextcloud, Vaultwarden, and Jellyfin/Plex to start. However, I want to make Nextcloud and Vaultwarden both available outside my network with a domain (I.e. nc.mydomain.com and vw.mydomain.com). Is this possible to do? To my understanding, both services have the same IP (since they're both on the same machine) so I'm not sure how I would configure it on my domain provider end. Also, does opening up these services put my others at a higher security risk?
