| - | To use [[ftp_modes#active|active mode]] with [[ftp|FTP protocol]], WinSCP needs to know an IP address, via which the server can reach your machine. If you have a direct connection to the network, WinSCP can ask operating system for the IP address. | + | This box includes options for the the [[ftp_modes#active|active mode]] of [[ftp|FTP protocol]]. |
| - | But if you are behind NAT router, it would return only the local network address. Then you need to check //Use following external IP address// and fill your external IP address in the box below. You can find your external IP address using many online services, like [[http://whatsmyip.net/|whatsmyip.net]] or [[https://www.google.com/search?q=what+is+my+ip|Google]]. | + | 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.

| + | 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. | ||
