At this point, Untangle has the basic configuration that will work for most networks. However, some networks require some more configurations. Any additional interfaces that are installed on Untangle NGFW were not available to be configured during the running of the initial configuration wizard. In this chapter, we will learn how to configure additional interfaces.

In addition, this chapter will teach you about the placement options for Untangle NGFW, and how the traffic is passed through the system.
