The demilitarized zone (DMZ) is a technology that enables the ONT to forward all received packets through a specified internal server. The technology

enables a computer in the LAN to be completely exposed to all users on the Internet or enables the mutual communication without restrictions between

a host with a specified IP address and other users or other servers on the Internet. In this way, many applications can run on the host with the specified

IP address. The host with the specified IP address receives all connections and files that can be identified.

If the LAN-side device does not provide website service or other network services, do not set the device to a DMZ host because all ports of a DMZ

host are opened to the Internet.

Table 1 describes the parameters related to the DMZ.

Port mapping indicates that the Intranet server is allowed to be open to the Extranet (for example, the Intranet provides the Extranet with a WWW

server or FTP server). Port mapping is to map the Intranet host IP address and port ID to Extranet IP address and corresponding port ID so that users

from Extranets can access the Intranet server. With port mapping, the users cannot see the Intranet IP address and they see the Extranet IP address.

1. Click Advanced Configuration > Forward Rules tab, and choose IPv4 Port Mapping. In the dialog box that is displayed, set the

parameters related to port mapping, as shown in Figure 1.
