Access Volumio via NO-IP

I just installed Volumio on my RPI and I was able to access it inside my network by using its IP address.

Now I want to achieve something else. I want to access the musics on my external HD on Volumio from outside my network using an authentication. So I was thinking if it’s possible to use NO-IP to achieve that.

I know that I will have to install NO-IP on my raspberry. If its possible to acccess it via NO-IP how can I do that?

Thanks in advance.

did you solved your problem? i’am looking for something like this
