What ports are needed for FTPS?
Explicit FTPS control connections take place on TCP port 21. Implicit FTPS control connections take place on TCP port 990. Once the control channel is established, the client and server negotiate a port for either PASSIVE or ACTIVE MODE data transfers.
What is the use of port 990?
Port 990 is known as the protected port, or the TLSPORT. You can disable implicit security for port 990, or reassign the protected port, by coding the TLSPORT statement in the server’s FTP. DATA configuration file.
Does FTPS use TCP or UDP?
Normal FTP uses port 21(TCP/UDP) for control and port 20(TCP/UDP) for data. FTP over TLS (FTPS) uses port 990(TCP/UDP) for control and port 989(TCP/UDP) for data. You will need to open both as FTPS prevents the router from detecting which port was negotiated for the data transfer.
Does port 21 need to be open for FTPS?
For the explicit option you only need ONE port: 22. For the implicit option you only need to have the firewall open for the control port: 8086 (which forwards internally to port 21 on your filezilla server). The question asked about FTPS, not SFTP.
How do I set up FTPS?
Enter a Name for the connection and select FTP as the protocol. Enter the URL for your file server in the Host field. If you left the port setting in your server as 21, enter that port number in the Port field otherwise, use the port number you went to within your FTPS server settings.
