A lot of good information here so I’ll add something a little different:
Do Not open any services to the internet, such as for remote access, until you are sure about what you are doing. Doing something like opening a port so you can watch Jellyfin anywhere sounds great, but doing it wrong pokes a huge security hole in your infrastructure.
Keep everything in your local network until you have a secure remote access setup. Even your home network may be untrustworthy if you’ve got things like IoT devices or compromised operating systems.











Think you got it mixed up. Superman was not the one on the receiving end.
