9. NAPT INBOUND SERVERS SETUP
The NAPT application converts IP addresses on a private network (designated as
"inside" or "LAN") to global IP addresses that can forward packets to another
registered network (designated as "outside" or "WAN"). It enables multiple PCs on
the LAN to access the Internet for the cost of one IP address. NAPT is disabled by
default and can be enabled by selecting Enable NAPT.
While NAPT is enabled, it will automatically create three NAPT Inbound Server IP
addresses. You can add, modify and delete NAPT server IP address.
For normal use it is not necessary to change the default settings.
Note: To save the settings, select "Save Configuration" and then click "Save".
