Public Property FTPMode As enumFTPMode |
The FTPMode determines whether the FTP connection is in active or passive mode. When going through a firewall you might need to use FTP_PASSIVE.
Passive mode is required in cases when your network has a firewall. Firewalls filter outside attempts to open a session with a high numbered port on your computer. In active mode, when an FTP client (the software running on your PC) contacts a server, it tells the server to send date to a random high-numbered port. The server then tries to open a session with that port. If you have firewall software running on your network, this mode may be blocked because it looks like an intrusion (hacking) attempt.
Most all servers will work with either mode.
