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.

CAUTION
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 5-9
describes the parameters related to the DMZ.
Table 5-9
Parameters related to the DMZ
Parameter
Description
Interface Name
Indicates the name of the WAN interface. If the WAN interface
is not in the port mapping table, the application requests from
the WAN connection are directly forwarded to the host in the
DMZ.
Host Address
Indicates the IP address of the DMZ host.
Enable DMZ
Indicates whether to enable 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.
Table 5-10
describes the parameters related to port mapping.
Table 5-10
Parameters related to port mapping
Parameter
Description
Interface
Indicates the name of the WAN interface where port mapping is
enabled.
Protocol
Indicates the protocol type of port mapping packet, which may
be TCP, UDP, or TCP/UDP.
External Start Port
Indicates the destination start port of the external data packet.
External End Port
Indicates the destination end port of the external data packet.
Internal Start Port
Indicates the internal destination start port of the port mapping
packet.
Internal End Port
Indicates the internal destination end port of the port mapping
packet.
External Source Start Port
Indicates the source start port of the external data packet.
External Source End Port
Indicates the source end port of the external data packet.
Internal Host
Indicates the IP address of the host to which the port is mapped.
External Source IP
Address
Indicates the source IP address of the external data packet.
Mapping Name
Indicates the name of the port mapping rule.
Enable PortMapping
Indicates whether to enable port mapping.

to apply the configuration.
The port trigger indicates that a specific Extranet port is automatically enabled when a
corresponding Intranet port sends a packet and the packet is mapped to the Intranet port on the
host.A specific mapping packet is sent from the ONT through the Intranet so that specific packets
of the Extranet can be mapped to the corresponding host. A specified port on the gateway firewall
is open to some applications for remote access. The port trigger can dynamically enable the open
port of the firewall.
Table 5-11
describes the parameters related to the port trigger.

Open Protocol
Indicates the protocol type of the open data packet.
Trigger Start Port
Indicates the destination start port of the port trigger packet.
Trigger End Port
Indicates the destination end port of the port trigger packet.
Open Start Port
Indicates the destination start port of the open packet.
