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.

Field Description
Appliance Name of the appliance associated with DNS proxy.
Segment Name of the segment applied to your appliances, if enabled.
DNS Proxy Enabled Whether the DNS Proxy is enabled. Select True or False.
Interface Name of the interface associated with the DNS proxy.
Server A Addresses IP addresses of Server A.
Server A Domains Domain addresses of Server A.
Server A Caching Whether you configured the server to be cached.
Server B Addresses IP addresses of Server B.
Server B Domains Domain addresses of Server B.
Server B Caching Whether you configured the server to be cached.

Configure DNS Proxy Policies

Complete the following steps to configure and define your DNS Proxy policies.

NOTE: This feature is only configurable if you have loopback interfaces configured.

  1. Choose whether you want to enable the DNS Proxy by selecting ON or OFF.

  2. Select the name of the loopback interface or the LAN-side label associated with your DNS proxy.

  3. Enter the IP addresses for Server A in the Server A Addresses field.

  4. Choose whether you want caching to be ON or OFF. If selected, the domain name to the IP address mapping is cached. By default, caching is ON.

  5. Enter the domain names of the Server A for the above IP addresses.

  6. Enter Server B IP addresses in the Server B Addresses field. Server B will be used if there are no matches to the Server A domains.

NOTE: You can Clear DNS Cache. This will erase the domain name to the IP address mapping you had cached for both Server A and B.
