I am green for NAS, just buy a new QNAP NAS TS-251.
I try to create a file share link (file property already set to public can be read / write) to my friend to download no any login account with browser only but fail.
I can download the file with the share link at intranet environment but can't download via internet with PC or mobile with browser only.
Does any Ching know why? Is it NAS restriction share file must using login account even you want share to public?
