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

that covers this information, however, it is written in such a way that the “layman” may have difficulty understanding what’s going on—and it doesn’t microsoft ftp client show exactly how to fix the 425 error code—so this Wiki will give instructions on how to set up your specific router. ”Abstract”[edit] This Wiki will go over the common technical reason(s) for error 425 being given after the http://geekswithblogs.net/Lance/archive/2008/01/24/ftp-error-425-quotcant-open-data-connection.quot.aspx FZS sends the 227 Passive command to the FTP client—regardless of what client is being used. This Wiki is written for the common user in a narrative tone—if a more in-depth technical Wiki is desired refer to the Network Configuration article. Narrative[edit] So, you've set up your FZS and it works for a local connection in your home, BUT you want to make your Local FTP Server accessible when you’re away—and you want to use encryption (SSL/TLS) to do https://wiki.filezilla-project.org/Setting_up_your_Router_to_Fix_the_%22425_code%22 so. You set up a Dynamic DNS (DynDNS) service to point to your FZS via your external IP address (don’t worry I’ll explain later in the Wiki). You’ve followed a how-to on setting up FZS to use SSL/TLS, but you've run into an issue—and after looking at the FZS Log you see the problem—right after the "227 Passive command" is given and acknowledged you see a 425 error. But even after summoning a Warlock, a Witch, and a Unicorn—you can’t fix it and wind up here reading this Wiki. The Problem[edit] More than likely the problem is that your FZS is requesting the FTP Client to use the Passive Ports defined in the FZS settings. And even though you’ve changed the settings in your Windows 7 or 8 Firewall you still can’t get your FTP Client to connect. Why? Well it’s complicated; the type of encryption that FZS uses doesn’t allow the router to “see” that you’d like to allow this communication, and thus the router blocks the data from being transferred. There are other programs you can use that would allow the router to see that a computer requested the information to come in, but you’ve configured FZS thus far, and in many ways it’s better that no one knows what this data is at all—it is your private information after all. Why the Router?[edit] OK, so I know that this Wiki isn’t suppos

I keep getting a 425 Can't open data connection error. We are not using NAT. What ports need to be ftp error open on my firewall to make a successful connection? Product: WS_FTP Professional Version: 9.0+ Platform: All supported OS Solution Answer/Solution: The 425 error means that the data channel is blocked or closed between you and the server you are trying to connect to. For Active (PORT) connections open port 21. Also open inbound high ports above 1024 to error 425 on the client. You can specify the range of ports the client uses for an Active data connection by clicking Tools, Options, Firewall, and check "Limit local port range". Open the matching port range you specify in your firewall. For Passive (PASV) connections open port 21, and disable any outbound packet or command filtering. If you still cannot get a successful connection, check all devices that are between the client and server to ensure that the proper ports are open (e.g. routers).Another possible cause of the 425 error code is the SSL requirements on the server. In the case of the following error message: 425 unable to build data connection: Operation not permitted. The server requires the FTP client to reuse the SSL session. In WS_FTP Pro (12.2 and later) to enable this option: Edit your site profileClick SSL on the left of the site optionscheck "Reuse SSL Session" and click OK to save the change.
