I configured FTP Service/Role on my Windows Server 2008 R2 machine. I am able to connect from the inside, but not from the outside. On the inside I tested using cmd prompt and IE FTP. On the outside, I am testing with FileZilla and IE FTP. From the outside, IE FTP prompts me to enter my username/pwd, but nothing happens. Page eventually times out and I get "Internet Explorer cannot display page". Using FileZilla, I get the following messages. Note FileZilla resolved domain name and authenticates. I did not configure FTP Wirewall Support on the FTP site. I am not sure if I need to do this. I set up basic authentication, non-ssl, not allowing anonymous. I testing with Windows Firewall Turned off and on (I added windows firewall rule for port 21). On my network firewall (Cisco), I added a rule to forward port 21 traffic to FTP Server.

Try to set your connection to ACTIVE MODE instead of PASV

Nothing seems to work. At this point I am not sure if its on my Network Firewall or something on my FTP Server. While inside the network FTP is working as expected. I just cannot get it to work from the outside. Not sure how to troubleshoot where the problem may be. Thanks for any tips. – obautista Jan 31 '11 at 13:00
just for your consideration and this only as a comparative scenario, have you considered installing filezilla server instead of using MS ftp? – redknight Feb 1 '11 at 19:36
