FRITZ!Box 6820 LTE Service

Setting up static port sharing

You can configure static port sharing to allow other other users in the Internet to access certain server services such as HTTP servers and remote maintenance servers, or online games and Internet applications in your FRITZ!Box home network.

Requirements / Restrictions

  • In order to use IPv4 Internet access, the FRITZ!Box must obtain a public IPv4 address from the Internet service provider.
  • In order to use IPv6 Internet access, the FRITZ!Box must obtain an IPv6 address from the Internet service provider and the server service or network device must support the IPv6 protocol.

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 application 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 "Port Sharing" or "Port Forwarding" tab.
  4. Click the button (Edit) for the (computer) name of the device that you would like to set up port sharing for,
    • or, if you have not configured any sharings for the device yet:
      1. Click "Add Device for Sharing".
      2. Select the (computer) name of the device from the drop-down list "Device".

        Note:If you cannot select the device, then you can select "Enter the IP address manually" and enter the IP address. Only devices that automatically obtain their IP settings (DHCP) from the FRITZ!Box are listed in the drop-down list.

  5. Click "New Sharing".
  6. Enable the option "Port Sharing".
  7. Select the entry "Other application" from the drop-down list "Application".
  8. Enter a name of your choice for the port sharing rule in the "Name" field.
  9. Select the IP protocol (TCP, UDP, ESP or GRE) required by the server service or application from the drop-down list "Protocol".

    Note:The IP protocols ESP and GRE are only required for VPN server services.

  10. 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 used by the server service or application to accept connections in the "Port to device", "to port" and "Port requested externally (IPv4)" field.
    • In order to enable port sharing for a port range:
      1. Enter the number of the first port used by the server service or application to accept connections in the "Port to device" field, and enter the last port in the "to port" field.
      2. Enter the number of the first port used by the server service or application to accept connections in the "Port requested externally (IPv4)" field.
  11. Enable the sharing.
  12. Click "OK" to save the settings.

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

With MyFRITZ! you can even access your FRITZ!Box over the Internet at all times if the FRITZ!Box receives a different public IP address from your Internet service provider on a regular basis:

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.
