For all Local and Public End IP address must begin after the IP Start

NAT Server Sets
The NAT Server Set is a list of LAN side servers mapped to external ports. If you
wish, you can make inside servers for different services, e.g., Web or FTP, visible
to the outside users, even though NAT makes your network appears as a single
machine to the outside world. A server is identified by the port number, e.g., Web
service is on port 80 and FTP on port 21.
As an example (see the following figure), if you have a Web server at
192.168.1.36nd a FTP server at 192.168.1.33, then you need to specify for port
80 (Web) the server at IP address 192.168.1.36 and for port 21 (FTP ) another at
IP address 192.168.1.33.
