Fritz!Box 4040, Manual

Changing IPv4 Settings
Overview
The IPv4 settings define the IPv4 network of the FRITZ!Box. Without
these settings there is no IPv4 network. In the FRITZ!Box an IPv4 net-
work is the default setting. The preconfigured IPv4 network is identical
in all FRITZ!Boxes. You can change the IPv4 settings.
Changes to the IPv4 settings can have the result that the FRITZ!Box
can no longer be reached. Make changes in this menu only if you are
proficient in network technology.
Application Example
In the following cases it is necessary to change the IPv4 address of the
FRITZ!Box:
• VPN connection: The home network of the FRITZ!Box is connected
with another FRITZ!Box network via a LAN-LAN linkup.
• The FRITZ!Box is integrated into an existing FRITZ!Box network and
both FRITZBoxes are operating in router mode (cascaded).
In both cases the FRITZ!Boxes involved cannot have identical IPv4 net-
works.
