Firewall(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Represents a Firewall Rule resource. Firewall rules allow or deny ingress traffic to, and egress traffic from your instances. For more information, read Firewall rules.

Attributes
Name	Description
allowed	MutableSequence[google.cloud.compute_v1.types.Allowed] The list of ALLOW rules specified by this firewall. Each rule specifies a protocol and port-range tuple that describes a permitted connection.
creation_timestamp	str [Output Only] Creation timestamp in RFC3339 text format. This field is a member of oneof_ _creation_timestamp.
denied	MutableSequence[google.cloud.compute_v1.types.Denied] The list of DENY rules specified by this firewall. Each rule specifies a protocol and port-range tuple that describes a denied connection.
description	str An optional description of this resource. Provide this field when you create the resource. This field is a member of oneof_ _description.
destination_ranges	MutableSequence[str] If destination ranges are specified, the firewall rule applies only to traffic that has destination IP address in these ranges. These ranges must be expressed in CIDR format. Both IPv4 and IPv6 are supported.
direction	str Direction of traffic to which this firewall applies, either INGRESS or EGRESS. The default is INGRESS. For EGRESS traffic, you cannot specify the sourceTags fields. Check the Direction enum for the list of possible values. This field is a member of oneof_ _direction.
disabled	bool Denotes whether the firewall rule is disabled. When set to true, the firewall rule is not enforced and the network behaves as if it did not exist. If this is unspecified, the firewall rule will be enabled. This field is a member of oneof_ _disabled.
id	int [Output Only] The unique identifier for the resource. This identifier is defined by the server. This field is a member of oneof_ _id.
kind	str [Output Only] Type of the resource. Always compute#firewall for firewall rules. This field is a member of oneof_ _kind.
log_config	google.cloud.compute_v1.types.FirewallLogConfig This field denotes the logging options for a particular firewall rule. If logging is enabled, logs will be exported to Cloud Logging. This field is a member of oneof_ _log_config.
name	str Name of the resource; provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression [a-z]([-a-z0-9]*[a-z0-9])?. The first character must be a lowercase letter, and all following characters (except for the last character) must be a dash, lowercase letter, or digit. The last character must be a lowercase letter or digit. This field is a member of oneof_ _name.
network	str URL of the network resource for this firewall rule. If not specified when creating a firewall rule, the default network is used: global/networks/default If you choose to specify this field, you can specify the network as a full or partial URL. For example, the following are all valid URLs: - https://www.googleapis.com/compute/v1/projects/myproject/global/networks/my-network - projects/myproject/global/networks/my-network - global/networks/default This field is a member of oneof_ _network.
priority	int Priority for this rule. This is an integer between 0 and 65535, both inclusive. The default value is 1000. Relative priorities determine which rule takes effect if multiple rules apply. Lower values indicate higher priority. For example, a rule with priority 0 has higher precedence than a rule with priority 1. DENY rules take precedence over ALLOW rules if they have equal priority. Note that VPC networks have implied rules with a priority of 65535. To avoid conflicts with the implied rules, use a priority number less than 65535. This field is a member of oneof_ _priority.
self_link	str [Output Only] Server-defined URL for the resource. This field is a member of oneof_ _self_link.
source_ranges	MutableSequence[str] If source ranges are specified, the firewall rule applies only to traffic that has a source IP address in these ranges. These ranges must be expressed in CIDR format. One or both of sourceRanges and sourceTags may be set. If both fields are set, the rule applies to traffic that has a source IP address within sourceRanges OR a source IP from a resource with a matching tag listed in the sourceTags field. The connection does not need to match both fields for the rule to apply. Both IPv4 and IPv6 are supported.
source_service_accounts	MutableSequence[str] If source service accounts are specified, the firewall rules apply only to traffic originating from an instance with a service account in this list. Source service accounts cannot be used to control traffic to an instance's external IP address because service accounts are associated with an instance, not an IP address. sourceRanges can be set at the same time as sourceServiceAccounts. If both are set, the firewall applies to traffic that has a source IP address within the sourceRanges OR a source IP that belongs to an instance with service account listed in sourceServiceAccount. The connection does not need to match both fields for the firewall to apply. sourceServiceAccounts cannot be used at the same time as sourceTags or targetTags.
source_tags	MutableSequence[str] If source tags are specified, the firewall rule applies only to traffic with source IPs that match the primary network interfaces of VM instances that have the tag and are in the same VPC network. Source tags cannot be used to control traffic to an instance's external IP address, it only applies to traffic between instances in the same virtual network. Because tags are associated with instances, not IP addresses. One or both of sourceRanges and sourceTags may be set. If both fields are set, the firewall applies to traffic that has a source IP address within sourceRanges OR a source IP from a resource with a matching tag listed in the sourceTags field. The connection does not need to match both fields for the firewall to apply.
target_service_accounts	MutableSequence[str] A list of service accounts indicating sets of instances located in the network that may make network connections as specified in allowed[]. targetServiceAccounts cannot be used at the same time as targetTags or sourceTags. If neither targetServiceAccounts nor targetTags are specified, the firewall rule applies to all instances on the specified network.
target_tags	MutableSequence[str] A list of tags that controls which instances the firewall rule applies to. If targetTags are specified, then the firewall rule applies only to instances in the VPC network that have one of those tags. If no targetTags are specified, the firewall rule applies to all instances on the specified network.

Classes

Direction

Direction(value)

Direction of traffic to which this firewall applies, either INGRESS or EGRESS. The default is INGRESS. For EGRESS traffic, you cannot specify the sourceTags fields.
