FRITZ!Box 7490 Service

Setting up 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 unsolicited data from the Internet.

If you configure port sharing, you can use Internet applications (for example chat software, online games, file-sharing software) that accept incoming connections from the Internet or allow users in the Internet to access certain server services (for example web server, remote maintenance server) in your FRITZ!Box home network.

The FRITZ!Box offers different options for sharing ports that can either be used separately or together. Which type of sharing is best depends on the requirements of the respective application or server service and your own personal preferences.

1 Setting up automatic port sharing

  • Set up the FRITZ!Box for automatic port sharing with UPnP if
    • you want to allow the application to set up all of the required port sharings in the FRITZ!Box on its own.
    • port sharing is not required for a server service.
    • the application supports the standards UPnP (Universal Plug and Play) or PCP (Port Control Protocol).

      Note:UPnP is supported by game consoles such as PlayStation, Wii U or Xbox, for example. The manufacturer can provide you with information on the respective application.

    • the application requires you to share many ports, or different ports are used each time the application is used.

2 Setting up MyFRITZ! accesses

  • Set up MyFRITZ! accesses in the FRITZ!Box if
    • you want to access a browser-based application (for example a web server) in the FRITZ!Box home network over the Internet.
    • you want to use a direct link in the device overview on to access the application.

3 Setting up static port sharing

  • Set up static port sharing in the FRITZ!Box if
    • you want to access a server service (for example a remote maintenance server) in the FRITZ!Box home network over the Internet.
    • the application does not support UPnP or PCP.
