a fixed number of public IP addresses, you can statically define which LAN IP
address will be translated to which NAT IP address and/or ports.
By default, the Router operates in NAPT routing mode. However, you can con-
trol your network translation by defining static NAT/NAPT rules. Such rules map
LAN computers to NAT IP addresses.
The NAT/NAPT mechanism is useful for managing Internet usage in your LAN,
or complying with various application demands. For example, you can assign
your primary LAN computer with a single NAT IP address, in order to assure its
permanent connection to the Internet. Another example is when an application
server with which you wish to connect, such as a security server, requires that
packets have a specific IP address - you can define a NAT rule for that address.
