There is one route added for each Ethernet interface in the system. For example, if there two
interfaces named lan and wan with the IPv4 addresses 192.168.0.10 and 193.55.66.77, this will
result in the following routes existing:
Route #
1
2
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 #
1
To include the core routes when the active routing table is displayed, it is necessary to explicitly
specify that all routes are to be displayed. This is shown in the example below.
