Accessing storage (NAS) over the internet via FTP

When the storage function (NAS) is used, you can allow FTP clients such as Cyberduck, FileZilla, or WinSCP to access certain contents of storage connected to the FRITZ!Box. This way you can give friends and relatives access to your pictures and videos from your last vacation over the internet, for example.

Note:You can also use just a web browser instead of an FTP client to access FRITZ!NAS contents over the internet safely and conveniently.

Requirements / Restrictions

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

  2. Click "Account Information" in the "Internet" menu.

      • ATTENTION!If you grant access to all folders, the user will also have access to all of the faxes, answering machine messages, and any online storage you have configured.
