We use a FortiGate 601E with v6.4.9.
Since the last firmware upgrade, FTP transfers with EPSV have been failing. Locally, the FTP server responds with "|||PORT|." However, the FortiGate translates this to "|||PORT" (the final "|" is missing).
Transfers with PASV continue to work.
I can't disable the session helper because it's required for PASV.
