3.6.18 Port mapping
The port mapping function enables you to access your LAN resources, such as resources on a web
server or an FTP server, through the internet.
−
Before the configuration, ensure that the Mesh device obtains a public IP address. Otherwise,
this function will not work properly. Common IPv4 addresses are categorized into Class A, Class B
and Class C. Private IP addresses of Class A range from 10.0.0.0 to 10.255.255.255. Private IP
addresses of Class B range from 172.16.0.0 to 172.31.255.255. Private IP addresses of Class C
range from 192.168.0.0 to 192.168.255.255.
−
ISPs may block unreported web services from being accessed with the default port number 80.
Therefore, when the default WAN port number is 80, please change it to an uncommon port
number (1025 to 65535), such as 9999.
−
The internal port number can be different from the external port number.
An example of configuring the port mapping function:
Scenario: You have an FTP server within the LAN.
Goal: Open the FTP server to internet users and enable family members to access the resources of
the FTP server when they are not at home.
Solution: You can configure the port mapping function to reach the goal. Assume that:
−
WAN IP address of the Mesh device: 202.105.11.22
−
Service port of the FTP server: 21
Configuration procedure:
Step 1
Run the Tenda WiFi App, and choose Settings > Advanced > Port Mapping.
