// EgressSecurityRule A rule for allowing outbound IP packets.
type EgressSecurityRule struct {

	// Conceptually, this is the range of IP addresses that a packet originating from the instance
	// can go to.
	// Allowed values:
	//   * IP address range in CIDR notation. For example: `192.168.1.0/24` or `2001:0db8:0123:45::/56`
	//     Note that IPv6 addressing is currently supported only in certain regions. See
	//     IPv6 Addresses (https://docs.cloud.oracle.com/iaas/Content/Network/Concepts/ipv6.htm).
	//   * The `cidrBlock` value for a Service, if you're
	//     setting up a security list rule for traffic destined for a particular `Service` through
	//     a service gateway. For example: `oci-phx-objectstorage`.
	Destination *string `mandatory:"true" json:"destination"`

	// 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"`

	// Type of destination for the rule. The default is `CIDR_BLOCK`.
	// Allowed values:
	//   * `CIDR_BLOCK`: If the rule's `destination` is an IP address range in CIDR notation.
	//   * `SERVICE_CIDR_BLOCK`: If the rule's `destination` is the `cidrBlock` value for a
	//     Service (the rule is for traffic destined for a
	//     particular `Service` through a service gateway).
	DestinationType EgressSecurityRuleDestinationTypeEnum `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"`

	TcpOptions *TcpOptions `mandatory:"false" json:"tcpOptions"`

	UdpOptions *UdpOptions `mandatory:"false" json:"udpOptions"`

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