FRITZ!Box 6840 LTE – Service

Accessing storage (NAS) over the Internet via FTP

If you use 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 allow friends and relatives to access 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

  • The FRITZ!Box must obtain a public IPv4 address or an IPv6 address from the Internet service provider.

Important:Some of the settings described here are only displayed if the advanced view is enabled in the user interface. The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS.

With MyFRITZ! you can even access your FRITZ!Box over the Internet at all times if its public IP address changes on a regular basis, for example after being automatically disconnected by your Internet service provider:

Note:If you already use a different dynamic DNS service, you can also use this service instead of MyFRITZ!.

  1. Set up a MyFRITZ! account in the FRITZ!Box.
  2. Determine the MyFRITZ! domain name of the FRITZ!Box.
