Block Known Ports
You can choose to block the FTP server from connecting to well-known ports.
Note: Known ports are published ports associated with services (for example, SMTP
is port 25).
This provides a second layer of protection against FTP bounce attacks, by preventing such
attacks from reaching well-known ports.
