ftp upload firewall settings

    Before ftp uploading files was no problem at all, but suddenly it became impossible to upload, delete the entire project and re-import it, and later found that it was the reason of the firewall. After turning off the firewall, the upload was successful. A bit of a pain in the ass. Then the question comes, how to set the upload when the firewall is open.
    Here are the reasons and methods for Baidu to arrive:
      2003 server is used to provide web and ftp services, and flashfxp is used to upload web pages remotely through the Internet. If the firewall is turned off, ftp uploading and downloading are normal, but it will not work if the windows firewall is enabled, even if the web, ftp and other services are listed as exceptions. The reason is that flashfxp actually needs to use more than 1024 tcp ports when it works, and the designation of the port is to be changed. Friends with similar experience, please give pointers, in this case, how to ensure that flashfxp can be uploaded and downloaded normally when the windows firewall is turned on? If you only know that ftp uses ports 20 and 21, please avoid opening your mouth.

Solution:
1. Turn on the windows firewall;
2. Add the IIS core program c:\windows\system32\inetsrv\inetinfo.exe in the "exceptions" of the
firewall settings; 3. In the "Advanced - Local Area Connection - In "Settings", uncheck FTP.
You're done.
