Well I initially designed it as a file server for me and my family to use while away from LAN. (I live in another city because of University...and the server is at their house, so I had to setup remote router settings first). My ISP provides a PPPoE network over fiber and that pretty much all I know about them tech-wise. They give me a username and password to access the internet. I guess I'll just leave it as it is now - at least my parents have a working home media server  and a ftp server and sharing files between all devices is easier. 

I will figure sth out in the future. Maybe a raspberry pi or an old otherwise purposeless laptop. 

Laptops are indeed actually very useful for this sort of thing if you don't need a multi-drive NAS.  Using my old one as a VoIP server at the moment as it means its automatically got battery backup and they naturally are designed to be lower power consumption devices than desktops.

So what you can try is to put your router to passthrough and configure ports on your modem to forward that port.
