NetDefendOS Route Definition Advantages
The NetDefendOS method of defining routes makes the reading and understanding of routing
information easier.
A further advantage with the NetDefendOS approach is that the administrator can directly specify a
gateway for a particular route and the following is true:
• A separate route does not need to be defined that includes the gateway IP address.
• It does not matter even if there is a separate route which includes the gateway IP address and
that routes traffic to a different interface.
Composite Subnets can be Specified
Another advantage with the NetDefendOS approach to route definition is that it allows the
administrator to specify routes for destinations that are not aligned with traditional subnet masks.
For example, it is perfectly legal to define one route for the destination IP address range 192.168.0.5
to 192.168.0.17 and another route for IP addresses 192.168.0.18 to 192.168.0.254. This is a feature
that makes NetDefendOS highly suitable for routing in highly complex network topologies.
