CIFS (Windows File Sharing)
Com m on I nt ernet File System ( CI FS) is a standard protocol support ed by m ost operat ing system s
in order t o share files across the net work. Using UPnP port m apping for CI FS allows users t o

copy files from the NAS, delete files on the NAS, or upload files t o the NAS from t he I nt ernet.
I f you configure UPnP port m apping t o allow CI FS access from t he WAN but cannot get it t o work,

or upload files t o t he share. See

num ber when using FTP t o access the NAS.
