Accessing storage (NAS) over the internet via FTP

When using the storage function (NAS), 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.

Requirements / Restrictions

  • For IPv4 internet access, the FRITZ!Box must obtain a public IPv4 address from the internet service provider.
  • For IPv6 internet access, the FRITZ!Box must obtain an IPv6 address from the internet service provider.

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

    • If the user should only be allowed to access a particular storage or folder, enable the option "Select folder".

      • ATTENTION!If you are using an IP telephone with the FRITZ!Box, the user will also have access to all of the messages recorded by the FRITZ!Box answering machine if you grant access to all folders.
