Shared files and printers on a computer are not available over the Internet

You cannot access shared files and printers on remote computers over your FRITZ!Box's Internet connection. It is also not possible to establish connections to Strato HiDrive nor establish other connections using the SMB or CIFS protocol. You also cannot use the SMB/CIFS protocol to establish connections from the Internet to the FRITZ!Box home network.

Now you can use applications that have to exchange NetBIOS packages with the Internet. This means that you can also access shared files and printers on remote computers using the FRITZ!Box's Internet connection.

1 SMB/CIFS protocol is blocked for security reasons

In order to guarantee the security of the computers in the FRITZ!Box home network, the FRITZ!Box blocks all access from the Internet over TCP and UDP ports 139 and 445, which are used for file and printer sharing ("NetBIOS Filter"). Applications that use the SMB/CIFS protocol to exchange information over the Internet can therefore not be used in the home network.

Workaround

  • Use secure transfer protocols or configure the applications to use secure transfer protocols (for example VPN, HTTPS, SFTP) for accessing the remote computers.

    Note:You can find information on using the application without the SMB/CIFS protocol and the necessary settings in the respective manual, or you can contact the manufacturer directly.
