Field Description
Rule Index This is sequence number for Address Mapping Sets
Rule Type This is the NAT mapping types.
Local
This is the starting local IP address (ILA).
Start IP
This is the ending local IP address (ILA). If the rule is
Local End for all local IPs, then put the Start IP as 0.0.0.0 and
IP
the End IP as 255.255.255.255. This field is N/A for

Note: For all Local and Public End IP address must begin after the IP Start
address, i.e., you can not have an End IP address beginning before the Start IP

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.
