File transfer protocol (FTP) session helper (ftp)

Chapter 10 Install and System Administration for FortiOS 5.0 : Session helpers : File transfer protocol (FTP) session helper (ftp)

The FTP session helper monitors PORT, PASV and 227 commands and NATs the IP addresses and port numbers in the body of the FTP packets and opens ports on the FortiGate unit as required.

To accept FTP sessions you must add a security policy with service set to any or to the FTP, FTP_Put, and FTP_GET pre-defined services (which all listen on TCP port 21).
