FTP Protocol Agent

One of the most common ways to transfer files across networks is using FTP. An FTP session starts with a control connection (by default, TCP port 21), and the data connection continues using a dynamically allocated port.

The Protocol Agent tracks the actual ports used so that ports can be opened only as needed for specific connections. This way, the whole range of possible dynamic ports does not need to be allowed in the policy.

The FTP Protocol Agent can change payload data, if necessary. The change can be required to handle NAT correctly.

The FTP Protocol Agent can also redirect traffic to a proxy service.

This Protocol Agent has parameters you can set in the Service properties.
