FRITZ!Box 3370 – 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 HTTP server, remote maintenance server) in your FRITZ!Box home network.

The FRITZ!Box offers different options for forwarding ports that can either be used separately or combined.

1 Setting up automatic port sharing via UPnP

  • Set up the FRITZ!Box for automatic port sharing with UPnP if
    • port sharing is required for an Internet application and not a server service.
    • the Internet application supports the UPnP (Universal Plug and Play) standard.

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

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

2 Setting up static port sharing

  • Configure static port forwarding in the FRITZ!Box if
    • you want to access server services in the FRITZ!Box home network from the Internet.
    • the Internet application does not support the UPnP standard.
