When WinSCP actively listens for incoming connections from an FTP server, it typically uses a random port number assigned by your operating system. This range usually falls between 49152 – 65535.
Here's a breakdown:
- Active vs. Passive FTP: FTP (File Transfer Protocol) uses two modes: active and passive. The port usage described here is relevant to active mode, where the client (WinSCP) listens for a connection from the server.
- Dynamic Port Range: The port range of 49152-65535 is a common dynamic or private port range. This means these ports are typically available for applications to use dynamically.
- Customization: You can limit the listening port range in WinSCP's settings if needed.
