Keeping pc awake but still auto logout and open port security issues.

[SticKx911]

I am using my htpc as a plex server. I am new to plex and open "server" access too. Ports opened online for remote access.

A) is there a way to set up the pc to lock automatically (so when I get distracted or the girlfriend forgets, tge kids can't come fuck shit up), but at the same time stay awake so plex can still run?

B) the opened/forwarded ports are different from default (if that matters), is there anything I need to do to keep things at least secure against simple attacks.

C) anyway to get the plex apps (like my mom's smart tv) to see remote servers? I can only seem to enter local ip's, am I missing something?

Thanks. And the obligitory sorry if this is covered in depth somewhere else.

Screensaver with the 'show logon screen' option ticked?
