CLI Reference

config global-dns-server policy

Use this command to configure a rulebase that matches traffic to DNS zones.

Traffic that matches both source and destination criteria is served by the policy. Traffic that does not match any policy is served by the DNS “general settings” configuration.

Before you begin:

  • You must have a good understanding of DNS and knowledge of the DNS deployment in your network.
  • You must have configured address objects, remote servers, DNS zones, and optional configuration objects you want to specify in your policy.
  • You must have read-write permission for global load balancing settings.

Syntax

config global-dns-server policy

edit <name>

set destination-address <datasource>

set dns64-list {<datasource> ...}

set dnssec-status {enable|disable}

set dnssec-validate-status {enable|disable}

set forward {first | only}

set forwarders <datasource>

set recursion-status {enable|disable}

set response-rate-limit <datasource>

set source-address <datasource>

set zone-list {<datasource> ...}

next

end

destination-address

Address object to specify the destination match criteria.

dns64-list

Specify one or more DNS64 configurations to use when resolving IPv6 requests.

dnssec-status

Enable/disable DNSSEC.

dnssec-validate-status

Enable/disable DNSSEC validation.

forward

  • first—The DNS server queries the forwarder before doing its own DNS lookup.
  • only—Only queries the forwarder. Does not perform its own DNS lookups.

forwarders

If the DNS server zone has been configured as a forwarder, specify the remote DNS servers to which it forwards requests.

recursion-status

Enable/disable recursion. If enabled, the DNS server attempts to do all the work required to answer the query. If not enabled, the server returns a referral response when it does not already know the answer.

response-rate-limit

Specify a rate limit configuration object.

source-address

Address object to specify the source match criteria.

zone-list

Specify one or more zone configurations to serve DNS requests from matching traffic.
