An optional description of your choice for the rule.
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: {@code 192.168.1.0/24} or {@code 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 {@code cidrBlock} value for a Service, if you're setting up a security list rule for traffic destined for a particular {@code Service} through a service gateway. For example: {@code oci-phx-objectstorage}.
Type of destination for the rule. The default is {@code CIDR_BLOCK}.
Allowed values:
{@code CIDR_BLOCK}: If the rule's {@code destination} is an IP address range in CIDR notation.
{@code SERVICE_CIDR_BLOCK}: If the rule's {@code destination} is the {@code cidrBlock} value for a Service (the rule is for traffic destined for a particular {@code Service} through a service gateway).
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.
The transport protocol. Specify either {@code all} or an IPv4 protocol number as defined in Protocol Numbers. Options are supported only for ICMP ("1"), TCP ("6"), UDP ("17"), and ICMPv6 ("58").
A rule for allowing outbound IP packets.
