Internet access (WAN)

i was looking for it but my english is not very good maybe i don’t know how to ask. I mean - how to connect to volumio from an external network, i.e. - I go to my son and uni from a computer (e.g. 10 km away in another town) I want to play from my volumio that works at home via the Internet. Which ports do I need to forward on the router to get to it, or, for example, to the DLNA volumio server

It’s pretty easy with myVolumio, see:

thank you, really simple - hadn’t thought of that
