Operating Instructions and Installation Instructions
Network Settings in the FRITZ!Box
FRITZ!Box 3390 103
IPv6 Settings
Click the “IPv6 Addresses” button to configure settings for
the IPv6 addresses in the local network.
Unique Local Adresses
Communication within the local network takes place via the
Unique Local Addresses (ULA). If no IPv6 Internet connection
is established, the network devices do not have a ULA and
communication between them is restricted. For this case you
can set the FRITZ!Box such that the network devices receive
the ULA from the FRITZ!Box.
DHCPv6 Servers in the Home Network
The FRITZ!Box is equipped with its own DHCPv6 server. The
DHCPv6 server of the FRITZ!Box is switched on by default.
The DHCPv6 server assigns the network devices their IPv6 set-
tings. These settings are used instead of the data in the router
advertisement messages. The DNS server, IPv6 prefixes or IPv6
addresses can all be assigned by DHCPv6. Define which IPv6
settings should be assigned by the DHCPv6 server.
UPnP Settings
The Universal Plug-and-Play (UPnP) service included in your
FRITZ!Box provides status information about the FRITZ!Box to
all connected computers. UPnP-compliant programs on these
computers can receive this information and use them to dis-
play the status of the FRITZ!Box (e.g., connection status, data
transmission). UPnP service thus allows you to monitor your
FRITZ!Box from a connected computer.
Here is how to change the UPnP settings:
1. Open the FRITZ!Box user interface (see page 29).
2. Enable the advanced view.
3. Configure the UPnP settings in the “Home Network > Net-
work” menu on the “Programs” page.
