Core Routes
NetDefendOS automatically populates the active routing table with Core Routes. These routes are
present for the system to understand where to route traffic that is destined for the system itself.
There is one route added for each interface in the system. In other words, two interfaces named lan
and wan, and with IP addresses 192.168.0.10 and 193.55.66.77, respectively, will result in the
following routes:
Route #
Interface
Destination
Gateway
1
core
192.168.0.10
2
core
193.55.66.77
When the system receives an IP packet whose destination address is one of the interface IPs, the
packet will be routed to the core interface. In other words, it is processed by NetDefendOS itself.
There is also a core route added for all multicast addresses:
Route #
Interface
Destination
Gateway
1
core
224.0.0.0/4
To include the core routes when you display the active routing table, you have to specify an option
to the routing command.
