Opnsense local dns

[bdario]

Hello to all,
OpnSense 19.7
interface 1 clients
interface 2 servers
interface 3 WAN
I would like to use OpnSense as DNS to resolve the local IP for clients and servers, and use Google DNS (8.8.8.8 8.8.4.4) to resolve public IPs
I don't found solutions on google, can someone help me?
Thanks a lot
Best regards
Dario
