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.

1 Preparations

Configuring a USB storage device for use as storage (NAS)

Configuring MyFRITZ!

Register the FRITZ!Box with MyFRITZ!Net so that it can always be reached on the internet at a fixed MyFRITZ! address:

2 Setting up FRITZ!Box users

To access the FRITZ!Box over the internet, you must set up users in the FRITZ!Box and allow them to access storage (NAS) contents from the internet:

3 Setting up internet access to storage (NAS)

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Permit Access" in the "Internet" menu.
  3. Click on the "FRITZ!Box Services" tab.
  4. Enable the option "Internet access to your storage media via FTP/FTPS enabled".
  5. Enter the desired port in the field "TCP port for HTTPS".
  6. If access from the internet should be encrypted, enable the option "Allow only secure FTP connections (FTPS)".

    Important:The software used to access the storage (for example a web browser, FTP client) must also support FTPS.

4 Accessing storage (NAS) over the internet

  1. Call up the address ftp://[MyFRITZ! address of the FRITZ!Box] in the FTP client. If the FRITZ!Box does not use the default FTP port 21, add the port used by the FRITZ!Box to the MyFRITZ! address.


  2. Enter the name and password of a FRITZ!Box user who is authorized to access NAS contents from the internet.
