- ↑ 1.0 1.1 1.2 UDP is the normal transport used for this protocol, but TCP can be used if you really want to (and your applications support it). In general there is good reason to use UDP over TCP, and you should leave well alone!
- ↑ 2.0 2.1 Whilst FTPS can use different ports to standard FTP, this is not necessary, and FTP servers are normally capable of accepting secure connections without using different TCP ports. Explicit FTPS uses the standard FTP ports and the client and server negotiate secure communications. Implicit FTPS uses different ports. Be aware that some firewalls are incapable of tracking explicit FTPS when it moves to use high ports for data transfer.
