9.3.2 Configuring Servers Behind SUA (Example)
Let's say you want to assign ports 21-25 to one 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.
