Configuring a Static IP Route
Overview
A static IP route is a description of a path to an IP subnet whose net-
work address is not known to the FRITZ!Box.
Application Example
Static IP routes are intended for the following situation:
• In the FRITZ!Box network there is a subnet whose network address
in the FRITZ!Box is unknown.
• The network devices in the subnet are to communicate with the
network devices of the FRITZ!Box or access the internet via the
FRITZ!Box.
• Only relevant for IPv4: The router that spans the subnet does not do
NAT (Network Address Translation).
How Static IP Routes Work
IP packets whose IP destination addresses are unknown are forwarded
to the internet by default. In the application described above, because
the FRITZ!Box does not know the destination addresses located in the
subnet, it forwards the packet to the internet. To prevent this from hap-
pening, the FRITZ!Box must know the network address of the subnet
and the IP address of the interface to the subnet. These two addresses
are required to configure a static route. Static IP routes are registered
in the routing table.
