My firewall asks if I want SmartFTP to "act as a server".

Most software firewalls will prompt you to "Allow SmartFTP to act as a server" when trying to connect to a site with "Passive" mode enabled. The software firewall behaves this way because the client is attempting to negotiate a data connection to the server. This is standard FTP protocol.

If you make the connection with "Passive" mode disabled, it will take care of the software firewall prompt. If disabling "Passive" mode causes the connection to the server to fail; it means that the server requires passive transfers. You will have respond to the software firewall prompt by saying "yes".
