        #       * properties<~Hash> - Hash containing the Firewall Rule properties
        #         * name<~String>             - The name of the Firewall Rule
        #         * protocol<~String>         - The protocol for the rule: TCP, UDP, ICMP, ANY

        #                                       Valid format: aa:bb:cc:dd:ee:ff. Value null allows all source MAC address
        #         * sourceIp<~String>         - Only traffic originating from the respective IPv4 address is allowed. Value null allows all source IPs

        #         * portRangeStart<~String>   - Defines the start range of the allowed port (from 1 to 65534) if protocol TCP or UDP is chosen.
        #                                       Leave portRangeStart and portRangeEnd value null to allow all ports
        #         * portRangeEnd<~String>     - Defines the end range of the allowed port (from 1 to 65534) if the protocol TCP or UDP is chosen.
        #                                       Leave portRangeStart and portRangeEnd null to allow all ports
