22 Σεπ 2021 · 1: Configure a service which allows access to control and data channel ports as follows. 2: Create an IP Policy which uses this service from and toward desired locations. This should reasonably be enough to allow communication between an FTPS server which has set data channel ports.
FTPS (also known as FTP Secure and FTP-SSL) is an extension to the commonly used File Transfer Protocol (FTP) that adds support for the Transport Layer Security (TLS) cryptographic protocol (previously known as the Secure Sockets Layer – SSL). 1.
