Two IPs can be assigned for system DNS. It is not possible to add more than 2 DNS IPs.

        Hi @siberprime, 

         

        It is possible to add 2 more as alternatives DNS servers in the CLI. Please refer to https://community.fortinet.com/t5/FortiGate/Technical-Tip-FortiGate-alt-primary-alt-secondary-DNS-server/ta-p/275269

        Please note (as mentioned in the KB) that the alternative servers are ONLY queried if the two other DNS servers are unable to resolve the hostname and return this response; they are NOT queried in case of a timeout.
