You can configure a DNS forwarder to forward DNS queries to external DNS servers.

Before you configure a DNS forwarder, you must configure a default DNS zone. Optionally, you can configure one or more FQDN DNS zones. Each DNS zone is associated with up to 3 DNS servers. When you configure a FQDN DNS zone, you specify one or more domain names. A DNS forwarder is associated with a default DNS zone and up to 5 FQDN DNS zones. When a DNS query is received, the DNS forwarder compares the domain name in the query with the domain names in the FQDN DNS zones. If a match is found, the query is forwarded to the DNS servers specified in the FQDN DNS zone. If a match is not found, the query is forwarded to the DNS servers specified in the default DNS zone.
