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.
