The primary use of a FortiGate unit is to protect our networks from attacks with its firewall features. The security policies will define the allowed network traffic. Now, let's us take a look at a set of base objects that we will use to create and manage the policies.
We have talked about interfaces in Chapter 1, First Steps. The firewall is able to operate both on physical and on virtual interfaces, including wireless interfaces, VLANS, and Virtual Domain (VDOM) links.
Note
VDOMs are a logical division of a single FortiGate unit into two or more virtual units that are independent from each other. We will talk about them in Chapter 4, High Availability.
There is a firewall interface that will receive the network traffic and an interface from which the aforementioned traffic will flow out of the device. We are able to establish a "direction" in which data is moving. This is the basic type of firewall control, and we can combine multiple interfaces (including...
