Operating Instructions and Installation Instructions

Network Settings in the FRITZ!Box
FRITZ!Box 3272 95
Unique Local Adresses
The communication within the local network takes place via
the Unique Local Addresses (ULA). If no IPv6 Internet connec-
tion 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 re-
ceive 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 26).
2. Enable the advanced view.
3. Configure the UPnP settings in the “Home Network / Net-
work” menu on the “Programs” page.
