When configuring either the Umbrella for Internal Networks or Umbrella for Active Directory (AD), the first step is to configure a Virtual Appliance (VA).
The purpose of VAs is to map internal source IP addresses to internal AD users and computers then forward external DNS queries from your network to one of the Umbrella global network data centers.
The VA does the following:
- Runs in a virtualized server environment and forwards local DNS queries to your existing DNS servers and remote DNS queries to Umbrella.
- If Internal Networks integration is enabled, captures the local IP of the computer making the external DNS request and reports it to the Umbrella global network.
- If Active Directory Integration is enabled, the VA forwards external DNS queries with non-sensitive metadata to the Umbrella global network to identify the AD user or computer.
