Chapter 11 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.
