Iis 7.5 ftp windows firewall

Great Tip. I had those preconfigured rules but they weren't taking effect for some reason. Just for the reference: " net stop msftpsvc " followed by a " net start msftpsvc " is the command line way of restarting the FTP service. It worked perfectly after I'd done that.

Opening port 21 in a firewall is an easy task, but this means that an FTP client will only be able to send commands, not transfer data. This is because data connections for FTP server are not allowed to pass through the firewall until the Data Channel has been allowed through the firewall. This may appear confusing to an FTP client, because the client will seem to be able to successfully log in to the server, but the connection may appear to timeout or stop responding when attempting to retrieve a directory listing from the server.

The challenges of working with FTP and firewalls doesn't end with the requirement of a secondary data connection; to complicate things even more, there are actually two different ways on how to establish data connection:. Some FTP clients require explicit action to enable passive connections, and some clients don't even support passive connections.

One such example is command-line Ftp. To add to the confusion, some clients attempt to intelligently alternate between the two modes when network errors happen, but unfortunately this does not always work. Some firewalls try to remedy problems with data connections with built-in filters that scan FTP traffic and dynamically allow data connections through the firewall. These firewall filters are able to detect what ports are going to be used for data transfers and temporarily open them on firewall so that clients can open data connections.

Some firewalls may enable filtering FTP traffic by default, but it is not always the case. This type of filtering is known as a type of Stateful Packet Inspection SPI or Stateful Inspection, meaning that the firewall is capable of intelligently determine the type of traffic and dynamically choose how to respond. Many firewalls now employ these features, including the built-in Windows Firewall. Skip to main content.

Improve this question. As Mathias suggested created a rule for port 21 in the Windows Advaned Firewall coniguration manager. This should get you started technet. There is already an inbound rule which allows traffic on port I also tried to open up port 20 but that didn't do any good.
