2. Now enter:
• Interface: wan
• Network: all-nets
• Gateway: isp_gw_ip
3. Click OK
Routes can Contain IPv4 or IPv6 Addresses
A single route can contain either an IPv4 or IPv6 address but not both. Routes that use IPv4 and
IPv6 addresses can be mixed in the same routing table. This topic is described further in
Section 3.2, “IPv6 Support”.
Routes to the Core Interface
NetDefendOS automatically populates the active routing table with Core Routes. These routes are
present for NetDefendOS to understand how to route traffic that is destined for the itself.
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 # 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 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.
Example 4.3. Displaying the Core Routes
This example illustrates how to display the core routes in the active routing table.
