devices, forms its own self-contained network.
Configuring FRITZ!Box as an IP Client
You can configure the FRITZ!Box such that it is integrated into
the existing network as an IP client and shares the existing In-
ternet connection in the network.
1. Connect the FRITZ!Box to the router or network with a ca-
ble as described in section Connecting with a Router or a
Network on page 19.
2. Open the FRITZ!Box user interface.
3. Select the “Internet > Account Information” menu.
4. Select the “More Internet service providers” entry from
the “Internet service provider” drop-down list.
5. Select the “Other Internet service provider” entry from
the second drop-down list.
6. From the “Connection” area, select the “External modem
or router” option.
7. In the “Operating Mode” area, select the setting “Share
existing Internet connection in the network (IP client
mode)”.
The FRITZ!Box is integrated into the existing network as an IP
client. The FRITZ!Box and the connected network devices re-
ceive an IP address from the IP address range of the existing
network. The FRITZ!Box and the connected network devices
are thus part of this network.
When the settings are applied the network address
range of the FRITZ!Box changes automatically.
