Define FTP Protocol parameters
The FTP Protocol Agent keeps track of the ports used in File Transfer Protocol (FTP) sessions. You can also use this Protocol Agent to redirect FTP traffic to a proxy service.
An FTP session starts with a control connection (by default, TCP port 21), and the communications continue using a dynamically allocated port. The FTP Protocol Agent can open the actual ports used in FTP sessions as needed so that the whole range of possible dynamic ports does not need to be allowed in the policy.
