DNS Proxy Policies
Configuration > Networking > DNS Proxy
The DNS (Domain Name Server) Proxy stores public IP addresses with their associated domain name. Server A is used primarily as a private DNS to backhaul traffic and Server B is used to match all other domains that are not included under Server A. Server B is also used for public (cloud services) to breakout traffic. See the table below for the field descriptions on this tab.
