Argument reference

• datacenter_id - (Required)[string] The Virtual Data Center ID.

• server_id - (Required)[string] The Server ID.

• nic_id - (Required)[string] The NIC ID.

• protocol - (Required)[string] The protocol for the rule: TCP, UDP, ICMP, ANY. Property cannot be modified after creation (disallowed in update requests).

• name - (Optional)[string] The name of the firewall rule.

• source_mac - (Optional)[string] Only traffic originating from the respective MAC address is allowed. Valid format: aa:bb:cc:dd:ee:ff. Value null allows all source MAC address. Valid format: aa:bb:cc:dd:ee:ff.

• source_ip - (Optional)[string] Only traffic originating from the respective IPv4 address is allowed. Value null allows all source IPs.

• target_ip - (Optional)[string] In case the target NIC has multiple IP addresses, only traffic directed to the respective IP address of the NIC is allowed. Value null allows all target IPs.

• port_range_start - (Optional)[int] Defines the start range of the allowed port (from 1 to 65534) if protocol TCP or UDP is chosen. Leave portRangeStart and portRangeEnd null to allow all ports.

• port_range_end - (Optional)[int] 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.

• icmp_type - (Optional)[string] Defines the allowed code (from 0 to 254) if protocol ICMP is chosen. Value null allows all codes.

• icmp_code - (Optional)[int] Defines the allowed code (from 0 to 254) if protocol ICMP is chosen.

• type - (Optional)[string] The type of firewall rule. If is not specified, it will take the default value INGRESS.
