I have a remote server(windows server 2008 r2) and I want to upload documents to this server by using ftp. I add the web server(iis 7.0) role and open the ftp services. Than I create an ftp site. It seems working, when i try to connect from command promt I can connect(both from my laptop and from the server itself.) But when i try to use filezilla and enter the credentials. It says connection timed out and so it does not show the directories. what might be the reason and how can i fix this?
