FTPS/FTPES does not work on Snap Guardian OS using Filezilla

Version 1

    There is a problem with connecting to the Guardian OS based Snap using FTPS/FTPES - FTP over explicit TLS/SSL.  This has been replicated on Snaps on 5.1.046, 5.2.056 and 5.2.056 SP1 using Filezilla 3.3.2.1.  Seen on Snap 110, 210, 620.  This appears to be a problem with FIlezilla 3.1.0 and above per http://bugs.proftpd.org/show_bug.cgi?id=3094

     

    We have verified that the following clients function at this time:

     

    Core FTP lite

    FireFtp

    ClassicFTP

    FlingFTP

     

    This issue will be addressed in a future release of Guardian OS.
