NAT

Figure 7-3 DFL-1500 plays the role as Virtual Server

As the above

Figure 7-3 illustrates, the server 10.1.1.5 provides FTP service. But it is located at the DMZ region behind

DFL-1500. And DFL-1500 will act as a Virtual Server role which redirects the packets to the real server 10.1.1.5. And you

can announce to the internet users that there exists a ftp server IP/port is 61.2.1.1/44444. So, all the internet users will

just connect the 61.2.1.1/44444 to get ftp service.

The feature of Virtual Server can only be available while DFL-1500 connects to the internet via

DEFAULT WAN

link.
