ftp server is down!

hello,

ftp server is down when i tired from external network for access to my files!

it's ok in localhost . what's problem?

i tired with ftp://myip

Thank you

i found problem it's for firewall . when i off it i can access to my file but when it's on no access!!

How solve it?

1) Open port 21 on the firewall

netsh advfirewall firewall add rule name="FTP (no SSL)" action=allow protocol=TCP dir=in localport=21

2) Activate firewall application filter for FTP (aka Stateful FTP) that will dynamically open ports for data connections

netsh advfirewall set global StatefulFtp enable
