Why do I need Passive FTP?
Because your hosting account and your WebSite Complete project are now behind a firewall, you must enable Passive FTP in your WebSite Complete account to publish your Web site.
You also need to enable Passive FTP if you have a dedicated IP or an SSL certificate associated with your hosting account and your WebSite Complete project, because your account is now located on a server with more advanced security. The change is to ensure a continued high level of security for your site and any customer information that you may be collecting through your site.
