I am running windows 2003 server with IIS 6.0 installed. I recently enabled TCP/IP filtering on the server and have kept open only the commonly used ports like 20,21,80, etc. Now the problem that I am facing is that whenever somebody tries to connect to the FTP using the Passive mode, then the user does not get the directory or file listing. When the user switches to PORT mode, then he is able to connect. Is there any way to allow passive mode without disturbing the existing settings.
Awaiting an early reply.
