Several console command are intended to manage accessibility of the ports
•kdctl allowed-ports list — to get all opened ports;
•kdctl allowed-ports open <port_number> [<protocol>] — to open a port having the specified number;
•kdctl allowed-ports close <port_number> [<protocol>] — to close a port having the specified number.
Semantics of their parameters is following:
•port_number — port number, required;
•protocol — protocol (TCP/UDP), optional, default value is TCP.
