System Overview

In this chapter, we will introduce the network topology for use with later chapters.

2.1 Typical Example Topology

In this chapter, we introduce a typical network topology for the DFL-1500. In Figure 2-1, the left half side is a DFL-1500 with one

LAN, one DMZ, and one WAN link. We will demonstrate the administration procedure in the later chapters by using the below

Figure 2-1.

The right half side contains another DFL-1500 connected with one LAN, one DMZ, and one WAN. You can imagine this is a

branch office of Organization_1. In this architecture, all the users under Organization can access sever reside in the Internet or DMZ

region smoothly. Besides, Organization_1 communicates with Organization_2 with a VPN tunnel established by the two DFL-1500

VPN/Firewall routers. The VPN tunnel secures communications between Organizations more safely.

We will focus on how to build up the topology using the DFL-1500 as the following

Figure 2-1. In order to achieve this purpose, we

need to know all the administration procedure.
