Transferring data using FTP without encryption is commonly referred to as Plain FTP and is NOT a secure means of transferring data.
We shall soon be disabling the option of using FTP without encryption. This normally occurs on Port 21.
There are a couple of alternatives to Plain FTP:
FTPS (FTP using TLS as the encryption layer)
- Use Explicit TLS
Initially connects on Port 21 and then initiates TLS
- Use Implicit TLS.
Connects on Port 990
You must select Implicit TLS and Port 990
Explicit TLS connects on the same port as Plain FTP (Port 21). When we disable Plain FTP it will prevent anyone using TLS in this mode from connecting.
Implicit TLS connects on port 990.
Data transfers using TLS require that Ports 50000-50200 are allowed outbound to our IP Addresses.
SFTP (File transfer using SSH)
SFTP uses SSH and therefore uses the Port 22.
SFTP requires no additional ports to be allowed to transfer data and so is the easiest to configure.
You or your network administrator will need to allow the necessary ports through your Firewall.
- TLS : 990, 50000-50200
- SSH : 22
You will need to allow the connections to our FTP servers which use the following IP address:
- 188.8.131.52 (ftp2.dynmark.com)
