ruleType property
When you want to forward DNS queries for specified domain name to resolvers
on your network, specify FORWARD.
When you have a forwarding rule to forward DNS queries for a domain to your
network and you want Resolver to process queries for a subdomain of that
domain, specify SYSTEM.
For example, to forward DNS queries for example.com to resolvers on your
network, you create a rule and specify FORWARD for
RuleType. To then have Resolver process queries for
apex.example.com, you create a rule and specify SYSTEM for
RuleType.
Currently, only Resolver can create rules that have a value of
RECURSIVE for RuleType.
