of a WAN IP address and a port number, so as to provide the external network access service.
Scenario 1: When you need to access IP cameras or PCs at home while you are away from home, port
mapping needs to be configured.
Scenario 2: When a server needs to be set up in the home network for Internet access, port mapping or
demilitarized zone (DMZ) needs to be configured.
Port mapping maps the WAN port IP address of a router to an internal network host and port so that Internet
users can proactively access hosts on the LAN.
DMZ forwards all packets from the Internet to DMZ hosts to provide the Internet access service.
3.8.2 Getting Started
Confirm the IP address of the target device in the internal network and service port ID.
Ensure that port mapping is available in the internal network.
Verify that your router has a public IP address. If the IP address is dynamic, changing it may cause port
mapping failure. In this case, you are advised to use a dynamic domain name service (DDNS) to resolve any
potential IP changes.
3.8.3 Configuration Steps
Mobile Phone View: Choose More > Switch to PC view > More > Advanced > Port Mapping.
PC View: Choose More > Advanced > Port Mapping.
Click Add. In the pop-up dialog box, enter the name, service type, protocol type, external port/range, internal IP
address, and internal port/range. A maximum of 50 port mapping rules can be configured.
Name: Enter a name for ease of maintenance.
Preferred Server: Select a service to be mapped, such as HTTP or FTP. The device will automatically fill in the
internal port number of the service. If you are not sure of the service, you can select Custom.
Protocol: Select the transport-layer protocol used by the selected service, such as ALL, TCP, or UDP. The
configuration on the server end must be consistent with that on the client end.
External Port/Range: Enter the port number used for external network access. You need to check the port
number in software, such as camera monitoring software.
Internal Server IP: Enter the LAN IP address used by external networks to access the device, such as the IP
address of an IP camera.
Internal Port/Range: Enter the port number used by an application accessed by external networks, such as
port 8080 used by the Web service.
