4.1. Overview
IP routing is one of the most fundamental functions of NetDefendOS. Any IP packet flowing
through a NetDefend Firewall will be subjected to at least one routing decision at some point in
time, and properly setting up routing is crucial for the system to function as expected.
NetDefendOS offers support for the following types of routing mechanisms:
• Static routing
• Dynamic routing
Additionally, NetDefendOS supports route monitoring to achieve route and link redundancy with
failover capability.
