FileZilla FTP Server error "425 Can't open data connection" after changing port 21 to 30

Question

I am using windows server + Xampp 1.8.3 and install FileZilla FTP Server => All configurations are ok! But when I change default FTP's port (21) to another port (30), it alerts:

STATUS:>    [17/04/2014 8:54:08 SA] Connecting to FTP server... xxx.xxx.xxx.xxx:30 (ip = xxx.xxx.xxx.xxx)...

You need to setup your passive ports in your Firewall. I wrote a tutorial not long ago: http://johandorper.com/log/filezilla-server-passive-ports
