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 Scenario
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 forwar
d
­
ed to the internet by default. In the application described above,
because the FRITZ!Box does not know the destination addresses that
belong to the subnet, it forwards the packet to the internet. To prevent
this from happening, 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.
Requirements
•
Static IP routes can be configured only when the advanced view is
enabled;
