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 or on the device in question.

Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Preparations

Determining ports and IP protocols

  1. 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:

  1. 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. If the tab is not displayed, enable the Advanced View first.
  4. Click the (Edit) button for the (computer) name of the device that you want to set up port sharing for, and then click "New Sharing" or "New Port Forwarding". If you have not configured 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. 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.
    • 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

With MyFRITZ! you can even access the 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 that service instead of MyFRITZ!.

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