Port trigger: By default, when an external network server initiates a connection request to an internal network client (such as video conference, VoIP, online game, etc.). ), the port corresponding to the router is not opened, which will lead to network disconnection. After setting the port trigger function, the internal network client will initiate the connection with the external network server first, thus triggering the router to open the corresponding port to ensure that the external network server can normally connect with the internal network client.
Preparatory work/about to start work
1. Connect the mobile phone/tablet/computer to the router's Wi-Fi, or connect the computer's network port with the router's LAN port with a network cable.
2. Enter192.168.3.1in the browser address bar to log in to the router Web management interface. If you use a mobile phone/tablet to connect to the router's Wi-Fi, please click the three points in the upper right corner of the page to switch to the computer version, and then do the following.
3. click more functions > security settings > NAT service.
port mapping
1. Click the plus icon in the upper right corner of the port mapping to add a port mapping rule.
2. Set up a new port mapping service.
● Service name: user-defined port mapping service name.
● Device: Computers that need to be configured as port mapping (such as Web servers and FTP servers) will only take effect when the device is online in terminal management.
● Protocol type: the protocol type adopted by the port mapping service, such as TCP and UDP. If you are not sure about the specific type, you can choose TCP/UDP.
● Internal port: the service port number of the computer that provides services to the outside world. Please consult the network administrator (the person who built the server) and fill it in.
● External port: the port number used by the external network to access this computer. Please consult the network management and fill in.
3. After setting, click Save.
4. Enter the IP address of the external network: external port number in the browser to access the computer in the internal network.
