| - | ===== Connections ===== | + | To use the active mode, WinSCP needs to know an IP address, via which the server can reach your machine. If you have a direct connection to the server, WinSCP can ask operating system for the IP address. That is the default behaviour, which corresponds to the //Retrieve the external IP address from operating system//. |

This is to help novice users, who do not realize that WinSCP defaults to SFTP (contrary to most other file transfer clients). | + | |

| + | When actively listening for incoming connections from the FTP server, WinSCP by default uses a random port number automatically assigned by the operating system. The range of port numbers used by the system is usually 49152 – 65535. If you want to change the range, check the //Limit listening ports to// checkbox. You will typically want to do that to match your firewall configuration with WinSCP. | ||
