Comments (56) | Share One of the most common questions I get about FTP has to do with error 425, "Can't open data connection." This is indeed a protocol level error that is defined in the RFC. Its meaning is obvious: the data connection (for a directory listing, upload, or download) was unable to be established. First - the most common solution: change the active/passive mode settings. But that might not work, and if it does its only a band-aid covering up the real problem. As I've mentioned in the past, one of the most common reasons that this error occurs is a misconfiguration of the FTP server software itself, related to SSL connections and firewalls, in which the

This FTP server does not allows passive mode connections. I can connect to the FTP server using Filezilla. I have developed a C# WCF service which connects to this FTP server, http://stackoverflow.com/questions/24694414/ftp-425-cant-open-data-connection-behind-iis using FTPWebRequest class. Here are the basic settings of the FTPWebRequest object: ftpreq.Proxy = null; ftpreq.KeepAlive = true; ftpreq.UsePassive = false; When I run the WCF service from Visual Studio(Ctrl+F5) it connects to the FTP server and downloads required files without any issues But when I host the service in my local IIS 7.5, it fails to connect to the FTP server with following error: The remote server returned an error: (425) Can't open data connection. After some googling on this problem, I tried playing around the firewall settings, but it was of no use. Not sure if it is related to some IIS security issue or something else. Any help would be highly appreciated wcf iis ftp share|improve this question edited Aug 1 at 6:20 Martin Prikryl 34.4k1549133 asked Jul 11 '14 at 9:27 user2830364 163 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote This is my way: Start\ Control Panel\ Windows Firewall\ Allowed Programs.

The Windows Server has static IP's.
