Serviio

I tried to search, but I didn't found any answers.

So if I share folder with Serviio, will it be possible access only with wlan or Lan?
I want to be sure that nobody (like from Internet) can't access to my shared files.

This look like very good software with Samsung bluray, thanks that!

it will only be accessed from your lan/ wlan, as long as you have enabled your wifi security properly.
