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 doesn't need to be defined that includes the gateway IP address. • It doesn't 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. Displaying Routing Tables It is important to note that routing tables that are initially configured by the administrator can have routes added, deleted and changed automatically during live operation and these changes will appear 148
