Setting up IPv6 port sharing in the FRITZ!Box

By default, the FRITZ!Box's firewall protects all of the devices in the FRITZ!Box home network from incoming connections and unwanted data from the Internet.

You can set up IPv6 port sharing to allow users in the Internet to access certain devices that are IPv6 compatible (for example NAS systems), web servers, or remote maintenance servers and other server services in your home network.

Note:If the device or server service can be accessed with a web browser, then you can use a MyFRITZ! Access to safely and conveniently access it over the Internet at any time.

Requirements / Restrictions

  • The FRITZ!Box must obtain an IPv6 address from the Internet service provider.
  • The device or server service you want to set up port sharing for must support the IPv6 protocol.
  • You can only access the device or server service with IPv6 Internet connections.

    Note:You can test whether a device can access the Internet over IPv6 on a particular Internet connection by calling up www.test-ipv6.com or www.ipv6-test.com on the device in question.

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

1 Preparations

Determining ports and IP protocols

  • Determine which ports and IP protocols the server service or device uses to accept incoming connections. Refer to the manufacturer for this information, for example consult the manual.

Configuring the computer's firewall

If the server service or application is installed on a computer with its own firewall (for example Windows firewall), you must also configure the firewall:

  • Configure the computer's firewall according to the manufacturer's instructions so that the server service or application can be accessed from the FRITZ!Box home network.

2 Setting up port sharing in the FRITZ!Box

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Permit Access" in the "Internet" menu.
  3. Click on the "IPv6" tab.
  4. Click the button (Edit) for the (computer) name of the device that you would like to set up port sharing for, and then click "New Port Forwarding" or "New Sharing".
    • or, if you have not set up any port sharings for the device yet:
      1. Click "New Device".
      2. Select the (computer) name of the device from the drop-down list "Name".

        Note:All network devices that automatically obtain their IPv6 settings (DHCP) from the FRITZ!Box are listed in the drop-down list "Name". If the network device is not listed, select the "User-defined" entry, then enter the name and Interface ID of the network device.

  5. Select the IP protocol (TCP or UDP) that you want to set up port sharing for from the drop-down list "Protocol".
  6. Enter the number(s) of the ports to be shared:
    • In order to enable port sharing for a single port:
      • Enter the number of the port for incoming Internet connections in the "From port" and "through port" or "to port" fields.
    • In order to enable port sharing for a port range:
      • Enter the first port for incoming Internet connections in the "From port" field and the last port in the "through port" or "to port" field.
  7. Click "OK" to save the settings.

3 Setting up the FRITZ!Box for access over the Internet

Setting up a MyFRITZ! account and determining the domain name

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 that supports IPv6, 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.

Maintaining a permanent Internet connection

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Account Information" in the "Internet" menu.
  3. Click on "Change connection settings".
  4. Enable the option "Maintain permanently (recommended for flat rates)".

    Important:If the option is not available, then the FRITZ!Box already remains permanently connected to the Internet.

  5. Click "Apply" to save the settings.
