EDIT: I'm rephrasing some sentences
Edit2: I gave up.
I just installed Fedora and to my surprise I can't use my NAS.
Through a SMB share I can see everything easily enough through GUI but I can't open any file, then I tried NFS.
With NFS I followed many tutorials to mount the shared folders, each one slightly different than the previous one, some told me to mount at /var/folder some told me to mount at /mnt/folder. I don't understand the difference. Anyway, now I know how to mount and how to put it in fstab so everything gets mounted on boot, not ideal but I can live with that.
What every single tutorial fails to say is that I can only access those shares as administrator and every time I want to open any file I have to type my password.
What I am missing here?
This tutorial is the one I finally followed
Here I noticed the the commenter added some options
