Let's say you want to assign ports 22-25 to one server, port 80 to another and assign a default server IP address of 192.168.1.35 as shown in the next figure.

Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server, port 80 to another (A in the example) and assign a default server IP address of 192.168.1.35 to a third (B in the example).
