Fields
kind

string

[Output only] Type of the resource. Returns compute#firewallPolicyRule for firewall rules and compute#packetMirroringRule for packet mirroring rules.
ruleName

string

An optional name for the rule. This field is not a unique identifier and can be updated.
description

string

An optional description for this resource.
priority

integer

An integer indicating the priority of a rule in the list. The priority must be a positive value between 0 and 2147483647. Rules are evaluated from highest to lowest priority where 0 is the highest priority and 2147483647 is the lowest priority.
match

object

A match condition that incoming traffic is evaluated against. If it evaluates to true, the corresponding 'action' is enforced.
match.srcIpRanges[]

string

CIDR IP address range. Maximum number of source CIDR IP ranges allowed is 5000.
match.destIpRanges[]

string

CIDR IP address range. Maximum number of destination CIDR IP ranges allowed is 5000.
match.layer4Configs[]

object

Pairs of IP protocols and ports that the rule should match.
match.layer4Configs[].ipProtocol

string

The IP protocol to which this rule applies. The protocol type is required when creating a firewall rule. This value can either be one of the following well known protocol strings (tcp, udp, icmp, esp, ah, ipip, sctp), or the IP protocol number.
match.layer4Configs[].ports[]

string

An optional list of ports to which this rule applies. This field is only applicable for UDP or TCP protocol. Each entry must be either an integer or a range. If not specified, this rule applies to connections through any port.

Example inputs include: ["22"], ["80","443"], and ["12345-12349"].
match.srcSecureTags[]

object

networkFirewallPolicies.list of secure tag values, which should be matched at the source of the traffic. For INGRESS rule, if all the srcSecureTag are INEFFECTIVE, and there is no srcIpRange, this rule will be ignored. Maximum number of source tag values allowed is 256.
match.srcSecureTags[].name

string

Name of the secure tag, created with TagManager's TagValue API.
match.srcSecureTags[].state

enum

[Output Only] State of the secure tag, either EFFECTIVE or INEFFECTIVE. A secure tag is INEFFECTIVE when it is deleted or its network is deleted.
match.destAddressGroups[]

string

Address groups which should be matched against the traffic destination. Maximum number of destination address groups is 10.
match.srcAddressGroups[]

string

Address groups which should be matched against the traffic source. Maximum number of source address groups is 10.
match.srcFqdns[]

string

Fully Qualified Domain Name (FQDN) which should be matched against traffic source. Maximum number of source fqdn allowed is 100.
match.destFqdns[]

string

Fully Qualified Domain Name (FQDN) which should be matched against traffic destination. Maximum number of destination fqdn allowed is 100.
match.srcRegionCodes[]

string

Region codes whose IP addresses will be used to match for source of traffic. Should be specified as 2 letter country code defined as per ISO 3166 alpha-2 country codes. ex."US" Maximum number of source region codes allowed is 5000.
match.destRegionCodes[]

string

Region codes whose IP addresses will be used to match for destination of traffic. Should be specified as 2 letter country code defined as per ISO 3166 alpha-2 country codes. ex."US" Maximum number of dest region codes allowed is 5000.
match.destThreatIntelligences[]

string

Names of Network Threat Intelligence lists. The IPs in these lists will be matched against traffic destination.
match.srcThreatIntelligences[]

string

Names of Network Threat Intelligence lists. The IPs in these lists will be matched against traffic source.
match.srcNetworkScope

enum

Network scope of the traffic source.
match.srcNetworks[]

string

Networks of the traffic source. It can be either a full or partial url.
match.destNetworkScope

enum

Network scope of the traffic destination.
action

string

The Action to perform when the client connection triggers the rule. Valid actions for firewall rules are: "allow", "deny", "apply_security_profile_group" and "goto_next". Valid actions for packet mirroring rules are: "mirror", "do_not_mirror" and "goto_next".
securityProfileGroup

string

A fully-qualified URL of a SecurityProfile resource instance. Example: https://networksecurity.googleapis.com/v1/projects/{project}/locations/{location}/securityProfileGroups/my-security-profile-group Must be specified if action is one of 'apply_security_profile_group' or 'mirror'. Cannot be specified for other actions.
tlsInspect

boolean

Boolean flag indicating if the traffic should be TLS decrypted. Can be set only if action = 'apply_security_profile_group' and cannot be set for other actions.
direction

enum

The direction in which this rule applies.
targetResources[]

string

A list of network resource URLs to which this rule applies. This field allows you to control which network's VMs get this rule. If this field is left blank, all VMs within the organization will receive the rule.
enableLogging

boolean

Denotes whether to enable logging for a particular rule. If logging is enabled, logs will be exported to the configured export destination in Stackdriver. Logs may be exported to BigQuery or Pub/Sub. Note: you cannot enable logging on "goto_next" rules.
ruleTupleCount

integer

[Output Only] Calculation of the complexity of a single firewall policy rule.
targetServiceAccounts[]

string

A list of service accounts indicating the sets of instances that are applied with this rule.
targetSecureTags[]

object

A list of secure tags that controls which instances the firewall rule applies to. If targetSecureTag are specified, then the firewall rule applies only to instances in the VPC network that have one of those EFFECTIVE secure tags, if all the targetSecureTag are in INEFFECTIVE state, then this rule will be ignored. targetSecureTag may not be set at the same time as targetServiceAccounts. If neither targetServiceAccounts nor targetSecureTag are specified, the firewall rule applies to all instances on the specified network. Maximum number of target label tags allowed is 256.
targetSecureTags[].name

string

Name of the secure tag, created with TagManager's TagValue API.
targetSecureTags[].state

enum

[Output Only] State of the secure tag, either EFFECTIVE or INEFFECTIVE. A secure tag is INEFFECTIVE when it is deleted or its network is deleted.
disabled

boolean

Denotes whether the firewall policy rule is disabled. When set to true, the firewall policy rule is not enforced and traffic behaves as if it did not exist. If this is unspecified, the firewall policy rule will be enabled.
