How to set up WS_FTP Professional to use FTP over SSL?

FTP > Configuring FTP over SSL
Windows 2008/IIS 7 allows a secure FTP connection via FTP over SSL. Note that this is not the same as SFTP (FTP via SSH), so you may have to experiment a bit with your FTP client settings to get a secure connection. Our tests were successful with the following.
  1. Click Connect -> Create Site
  2. In the Site Name field, enter your domain name and click next
  3. Select FTP/SSL (Auth SSL) and click next
  4. Fill out the remaining fields as follows:
    • Server Address – Enter FTP address( like, which can be found in Control Panel.
    • User Name – Enter your FTP username.
    • Password – Enter the password for this user.
  5. Click Next to complete the Wizard
Note: If you receive a generic "could not connect" error, or in implicit mode see an attempted connection to port 21, you have a configuration error. Please cut and paste the login information from Control Panel to make sure you are supplying the proper credentials.
