Little help please

it appears it may be some time before we get a mobile roon so i’m trying plex for the first time. but i have a big problem! I don’t understand port forwarding and it seems my subnet router doesn’t have UPnP which is suppose to make the process easier. anyone comprehend this well enough to explain how i can take my music on the road with plex?
