How to Enable FTP Traffic in the Windows Firewall
Service Pack 2 of the Microsoft Windows XP operating system and all subsequent Windows operating systems come bundled with Windows Firewall, a security component intended to protect Windows computers from unwanted incoming connections. While this is desirable in most circumstances, the Firewall can sometimes block connections that users want or need, such as FTP. In such cases, an exception needs to be defined in the Firewall settings to allow those connections.
