Chapter 9 Network Address Translation (NAT)
Port Forwarding Example
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.
