Currently, we are using the 1200D firewall in our corporate office. In the Box, we have created multiple ADOMs and multiple ISP links as well. Hover, we are facing the issues in DNS lookup field error in the sum of the websites. And we have already configured Global VDOMs in global DNS like 18.104.22.168 and 22.214.171.124.
But, when we are facing the issue of a DNS lookup failed error, we have to change the DNS IP as per the ISP providing the own DNS IPs.
Could you tel me any option available in FortiGate to configure the multiple DNS IPs? If the option it's available please
