Win2003 FileZilla Server Client cannot connect after firewall is turned on (FTP)

The site has a way to add an exception to the window firewall, such as 21,20 then, FileZilla Server.exe program to add some of this solution can be solved, but I do not.

Windows Firewall open 21 port, when I use the desktop client landing ftp after the problem of unable to list the directory, I will first shut down the firewall, and then the client connection is normal, it also needs to add FileZilla to the exception in the firewall, add the program in the exception, Locate the FileZilla Server.exe of the FileZilla installation directory and click OK to add to the exception to reconnect with the client. Everything's fine.

There is also a way in the firewall, this way my other machines can operate this way

Open the Local Area Connection Properties dialog box and switch to the Advanced tab. Click the Settings button in the lower-right corner of the dialog box to open the Advanced Settings dialog box.

Step 3rd, in the Default Services tab, users can set up the service categories that are open to the firewall on the premise that they are enabled. Because of the need to provide FTP services, you only need to open the service. Select the FTP server option in the list of services, and the Open Service Settings dialog box requires the computer name to be filled in. Leave the default content and click OK to complete the setup

As shown in the picture, this can be normal, but I still do not, is trying to find a way.

Just to add
