We are in the process of upgrading a tz170 (standard) to a nsa240 (enhanced)
Active and Passive both usually connect, and work sporadically. More often than not the connection times out. This has been seen using ftp client software and windows explorer. Works perfectly on tz170, so the nsa240 being the only new element in the equation I'm lead to believe the enhanced OS handles ftp traffic differently?
The ftp server software on the remote end is Globalscape ftp, running on a windows 03 server, and is hosted.
Sonicwall was no help, they say that the nsa is not responsible for dropping the connection
