FRITZ!Box 3390 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.

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

Requirements / Restrictions

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

    Important:The FRITZ!Box is not accessible from the Internet over IPv4 when used on a DS-Lite ("Dual-Stack Lite") connection. When DS-Lite is active, the status "IPv4 over DS Lite" is displayed under "Connections" on the "Overview" page of the FRITZ!Box user interface.

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

  • Consult the manual or ask the manufacturer to find out which ports and/or IP protocols the Internet application or server service uses to accept incoming connections.

Configuring the computer's firewall

If the server service or Internet 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 so that the server service or Internet application can be accessed from the FRITZ!Box home network.

    Note:You can find information on configuring the firewall in its manual, or consult its manufacturer directly.

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 "New Port Sharing" or "New Port Forwarding".
  5. Select "Other applications" from the drop-down list "Port sharing enabled for" or "Port forwarding enabled for".
  6. Enter a name of your choice for the port sharing rule in the "Name" field.
  7. Select the IP protocol (TCP, UDP, ESP or GRE) required by the server service or Internet application from the drop-down list "Protocol".

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

  8. 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 Internet application to accept connections in the "From port" and "to Port" (or "through port") fields.
    • In order to enable port sharing for a port range:
      1. Enter the number of the first port used by the server service or Internet application to accept connections in the "From port" field, and enter the last port in the "to port" (or "through port") field.
      2. Enter the number of the first port used by the server service or Internet application to accept connections in the "to Port" field.
  9. Select the network device (for example a computer) with the server service or network device that you are setting up port sharing for:
    • If the network device's IP address is dynamically assigned by the FRITZ!Box's DHCP server:
      • Select the (computer) name of the network device from the drop-down list "to computer".
    • If the network device has a static IP address:
      1. Select "Enter the IP address manually" from the drop-down list "to computer".
      2. Enter the IP address of the network device.
  10. Click "OK" to save the settings.

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

The following steps are only necessary if you want the server service (for example HTTP, FTP, VPN, remote maintenance or NAS server) to be accessible over the Internet under a unique address at all times:

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, 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 your settings.
