Application Port

The application backend service needs to declare a fixed port for providing HTTP service. This port must be declared in the port field of the application configuration file.

The system allocates two independent access ports for each application, for HTTP and HTTPS access respectively. Requests with path prefixes matching proxy_path will be forwarded to the application backend service port.

If the application has configured service port and forwarding path, the request processing flow is as follows:

Remote Access

Applications support remote access via UGREENlink without additional configuration. The system allocates a dedicated external access domain for each application.

When accessing via UGREENlink, the system automatically detects the network connectivity between the current client and the NAS device. If the client and NAS device are on the same local network, it will redirect to the direct connection domain (where the DNS-resolved IP is the device's LAN IP) for faster access.

Applications can listen on other ports not declared in the configuration file, but the system will not provide proxy forwarding services for these ports, nor will it check whether these ports are occupied at startup. These ports also cannot be accessed remotely via UGREENlink.
