Chapter 8 Network Address Translation (NAT) Screens

Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the 
example), port 80 to another (B in the example) and assign a default server IP address of 
192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP 
assigns the WAN IP address. The NAT network appears as a single host on the Internet.

IP address assigned by ISP.

Figure 42   Multiple Servers Behind NAT Example

You must create a firewall rule in addition to setting up SUA/NAT, to allow traffic from the 
WAN to be forwarded through the Prestige.
