Overview
When passing RuleDefinition as input to an Aws::Client method, you can use a vanilla Hash:
{
match_attributes: { # required
sources: [
{
address_definition: "AddressDefinition", # required
},
],
destinations: [
{
address_definition: "AddressDefinition", # required
},
],
source_ports: [
{
from_port: 1, # required
to_port: 1, # required
},
],
destination_ports: [
{
from_port: 1, # required
to_port: 1, # required
},
],
protocols: [1],
tcp_flags: [
{
flags: ["FIN"], # required, accepts FIN, SYN, RST, PSH, ACK, URG, ECE, CWR
masks: ["FIN"], # accepts FIN, SYN, RST, PSH, ACK, URG, ECE, CWR
},
],
},
actions: ["CollectionMember_String"], # required
}
The inspection criteria and action for a single stateless rule. AWS Network Firewall inspects each packet for the specified matching criteria. When a packet matches the criteria, Network Firewall performs the rule's actions on the packet.

Instance Attribute Details
#actions ⇒ Array<String>
The actions to take on a packet that matches one of the stateless rule definition\'s match attributes. You must specify a standard action and you can add custom actions.
aws:forward_to_sfe
for a rule that the packet matches, or
if the packet doesn\'t match any stateless rule and you specify
aws:forward_to_sfe
for the StatelessDefaultActions
setting for the
FirewallPolicy.
For every rule, you must specify exactly one of the following standard actions.
aws:pass - Discontinues all inspection of the packet and permits it to go to its intended destination.
aws:drop - Discontinues all inspection of the packet and blocks it from going to its intended destination.
aws:forward_to_sfe - Discontinues stateless inspection of the packet and forwards it to the stateful rule engine for inspection.
Additionally, you can specify a custom action. To do this, you define a
custom action by name and type, then provide the name you\'ve assigned
to the action in this Actions
setting. For information about the
options, see CustomAction.
To provide more than one action in this setting, separate the settings
with a comma. For example, if you have a custom PublishMetrics
action
that you\'ve named MyMetricsAction
, then you could specify the
standard action aws:pass
and the custom action with [“aws:pass”,
“MyMetricsAction”]
.
#match_attributes ⇒ Types::MatchAttributes
Criteria for Network Firewall to use to inspect an individual packet in stateless rule inspection. Each match attributes set can include one or more items such as IP address, CIDR range, port number, protocol, and TCP flags.
