type UpdateSecurityRuleDetails struct {

	// Direction of the security rule. Set to `EGRESS` for rules to allow outbound IP packets,
	// or `INGRESS` for rules to allow inbound IP packets.
	Direction UpdateSecurityRuleDetailsDirectionEnum `mandatory:"true" json:"direction"`

	// The Oracle-assigned ID of the security rule that you want to update. You can't change this value.
	// Example: `04ABEC`
	Id *string `mandatory:"true" json:"id"`

	// The transport protocol. Specify either `all` or an IPv4 protocol number as
	// defined in
	// Protocol Numbers (http://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml).
	// Options are supported only for ICMP ("1"), TCP ("6"), UDP ("17"), and ICMPv6 ("58").
	Protocol *string `mandatory:"true" json:"protocol"`

	// An optional description of your choice for the rule. Avoid entering confidential information.
	Description *string `mandatory:"false" json:"description"`

	// Conceptually, this is the range of IP addresses that a packet originating from the instance
	// can go to.
	// Allowed values:
	//   * An IP address range in CIDR notation. For example: `192.168.1.0/24` or `2001:0db8:0123:45::/56`
	//     IPv6 addressing is supported for all commercial and government regions. See
	//     IPv6 Addresses (https://docs.oracle.com/iaas/Content/Network/Concepts/ipv6.htm).
	//   * The `cidrBlock` value for a Service, if you're
	//     setting up a security rule for traffic destined for a particular `Service` through
	//     a service gateway. For example: `oci-phx-objectstorage`.
	//   * The OCID (https://docs.oracle.com/iaas/Content/General/Concepts/identifiers.htm) of a NetworkSecurityGroup in the same
	//     VCN. The value can be the NSG that the rule belongs to if the rule's intent is to control
	//     traffic between VNICs in the same NSG.
	Destination *string `mandatory:"false" json:"destination"`

	// Type of destination for the rule. Required if `direction` = `EGRESS`.
	// Allowed values:

	//     Service (the rule is for traffic destined for a
	//     particular `Service` through a service gateway).
	//   * `NETWORK_SECURITY_GROUP`: If the rule's `destination` is the OCID (https://docs.oracle.com/iaas/Content/General/Concepts/identifiers.htm) of a

	DestinationType UpdateSecurityRuleDetailsDestinationTypeEnum `mandatory:"false" json:"destinationType,omitempty"`

	IcmpOptions *IcmpOptions `mandatory:"false" json:"icmpOptions"`

	// A stateless rule allows traffic in one direction. Remember to add a corresponding
	// stateless rule in the other direction if you need to support bidirectional traffic. For
	// example, if egress traffic allows TCP destination port 80, there should be an ingress
	// rule to allow TCP source port 80. Defaults to false, which means the rule is stateful
	// and a corresponding rule is not necessary for bidirectional traffic.
	IsStateless *bool `mandatory:"false" json:"isStateless"`

	// Conceptually, this is the range of IP addresses that a packet coming into the instance
	// can come from.
	// Allowed values:

	//     traffic between VNICs in the same NSG.
	Source *string `mandatory:"false" json:"source"`

	// Type of source for the rule. Required if `direction` = `INGRESS`.
	//   * `CIDR_BLOCK`: If the rule's `source` is an IP address range in CIDR notation.
	//   * `SERVICE_CIDR_BLOCK`: If the rule's `source` is the `cidrBlock` value for a
	//     Service (the rule is for traffic coming from a
