Thanks. We'll let you know when a new response is added.

ftp uses TCP ports 20/21
tftp uses UDP port 69
sftp uses TCP port 22 (same as SSH) – this could be an issue

You can block the ports listed above – but if there is a requirement to support SSH the there could be an issue since sftp uses the same port.
