list-firewall-rules

Description

Retrieves the firewall rules that you have defined for the specified firewall rule group. DNS Firewall uses the rules in a rule group to filter DNS network traffic for a VPC.

A single call might return only a partial list of the rules. For information, see MaxResults .

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

list-firewall-rules is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: FirewallRules

Synopsis

  list-firewall-rules
--firewall-rule-group-id <value>
[--priority <value>]
[--action <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--firewall-rule-group-id (string)

The unique identifier of the firewall rule group that you want to retrieve the rules for.

--priority (integer)

Optional additional filter for the rules to retrieve.

The setting that determines the processing order of the rules in a rule group. DNS Firewall processes the rules in a rule group by order of priority, starting from the lowest setting.

--action (string)

Optional additional filter for the rules to retrieve.

The action that DNS Firewall should take on a DNS query when it matches one of the domains in the rule's domain list:

  • ALLOW - Permit the request to go through.
  • ALERT - Permit the request to go through but send an alert to the logs.
  • BLOCK - Disallow the request. If this is specified, additional handling details are provided in the rule's BlockResponse setting.

Possible values:

  • ALLOW
  • BLOCK
  • ALERT

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

To list firewall rules

The following list-firewall-rules example list all of your DNS Firewall rules within a firewall rule group.

aws route53resolver list-firewall-rules \
    --firewall-rule-group-id rslvr-frg-47f93271fexample

Output:

{
    "FirewallRules": [
        {
            "FirewallRuleGroupId": "rslvr-frg-47f93271fexample",
            "FirewallDomainListId": "rslvr-fdl-9e956e9ffexample",
            "Name": "allow-rule",
            "Priority": 101,
            "Action": "ALLOW",
            "CreatorRequestId": "d81e3fb7-020b-415e-939f-EXAMPLE11111",
            "CreationTime": "2021-05-25T21:44:00.346093Z",
            "ModificationTime": "2021-05-25T21:44:00.346093Z"
        }
    ]
}

Output

NextToken -> (string)

If objects are still available for retrieval, Resolver returns this token in the response. To retrieve the next batch of objects, provide this token in your next request.

FirewallRules -> (list)

A list of the rules that you have defined.

This might be a partial list of the firewall rules that you've defined. For information, see MaxResults .

(structure)

A single firewall rule in a rule group.

FirewallRuleGroupId -> (string)

The unique identifier of the firewall rule group of the rule.

FirewallDomainListId -> (string)

The ID of the domain list that's used in the rule.

Name -> (string)

The name of the rule.

Priority -> (integer)

The priority of the rule in the rule group. This value must be unique within the rule group. DNS Firewall processes the rules in a rule group by order of priority, starting from the lowest setting.

Action -> (string)

The action that DNS Firewall should take on a DNS query when it matches one of the domains in the rule's domain list:

  • ALLOW - Permit the request to go through.
  • ALERT - Permit the request to go through but send an alert to the logs.
  • BLOCK - Disallow the request. If this is specified, additional handling details are provided in the rule's BlockResponse setting.

BlockResponse -> (string)

The way that you want DNS Firewall to block the request. Used for the rule action setting BLOCK .

  • NODATA - Respond indicating that the query was successful, but no response is available for it.
  • NXDOMAIN - Respond indicating that the domain name that's in the query doesn't exist.
  • OVERRIDE - Provide a custom override in the response. This option requires custom handling details in the rule's BlockOverride* settings.

BlockOverrideDomain -> (string)

The custom DNS record to send back in response to the query. Used for the rule action BLOCK with a BlockResponse setting of OVERRIDE .

BlockOverrideDnsType -> (string)

The DNS record's type. This determines the format of the record value that you provided in BlockOverrideDomain . Used for the rule action BLOCK with a BlockResponse setting of OVERRIDE .

BlockOverrideTtl -> (integer)

The recommended amount of time, in seconds, for the DNS resolver or web browser to cache the provided override record. Used for the rule action BLOCK with a BlockResponse setting of OVERRIDE .

CreatorRequestId -> (string)

A unique string defined by you to identify the request. This allows you to retry failed requests without the risk of executing the operation twice. This can be any unique string, for example, a timestamp.

CreationTime -> (string)

The date and time that the rule was created, in Unix time format and Coordinated Universal Time (UTC).

ModificationTime -> (string)

The date and time that the rule was last modified, in Unix time format and Coordinated Universal Time (UTC).
