4.2.2. Static Routing
this way is easier to understand, making errors less likely.
Many other products do not use the specific interface in the routing table, but specify the IP address
of the interface instead. The routing table below is from a Microsoft Windows XP workstation:
====================================================================
Interface List
0x1 ........................... MS TCP Loopback interface
0x10003 ...00 13 d4 51 8d dd ...... Intel(R) PRO/1000 CT Network
0x20004 ...00 53 45 00 00 00 ...... WAN (PPP/SLIP) Interface
===================================================================
===================================================================
Active Routes:
Network Destination
10.4.2.143
10.255.255.255
85.11.194.33
127.0.0.0
192.168.0.0
192.168.0.10
192.168.0.255

Default Gateway:
===================================================================
Persistent Routes:
None
The corresponding routing table in NetDefendOS will be similar to the following:
Flags Network
----- ------------------ -------- -------------- --------- ------
192.168.0.0/24
10.0.0.0/8
0.0.0.0/0
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.
