DNS Service
You can create local DNS servers for your network. Depending on your requirements, you can manually maintain your entries (primary DNS server) or use it as a jumping point, where the server refers to an outside source (secondary DNS server). A local primary DNS server works similarly to the DNS server addresses configured in Network > DNS Settings, but you must manually add all entries. This allows you to add a local DNS server to include specific URL and IP address combinations.
You can set an option to ensure this type of DNS server is not the authoritative server. When configured as a recursive DNS, the FortiProxy unit will check its internal DNS server (primary or secondary). If the request cannot be fulfilled, it will look to the external DNS servers. This is known as a split DNS configuration.
To configure DNS servers and zones, go to Network > DNS Service.
