Unable to browse/list Directories when using secure FTP and TMG

Posted on 2011-04-28
Last Modified: 2012-05-11
We are attempting to setup secure ftp on a 2008 server using TMG.  Connections are successful but the folder directory is not listed.  We have followed the workaround but that is not working for us.  Any help is appreciated.

    When you can connect but not list directories or transfer files that means your FTP control channel is connected but your FTP data channel is blocked.  If you use an FTP client that has logging capabilities you can find which port the data channel is supposed to be on by looking at the last 2 numbers in the PORT command (active mode) or in the server's response to the PASV command (passive mode.)

    The FTP Application filter is what dynamically deals with that.  The App Filter must remain bound to the FTP Protocol being used in the Rule.  Make sure you are using the correct Protocol, needs to be the one mark as "server" which is an inbound Protocol.  Also make sure your FTP Server is using standard ports for the site,...if you use custom odd-ball ports it will likely fail.
