Internal Networks allow Umbrella to manage traffic sent from computers on the subnets or internal IP addresses of your networks. You can associate an Internal Network with a Network, Site, or Network Tunnel identity.

An Internal Network identity defines a subnet that's non-routable (or RFC 1918 compliant). For example, if your Internal Network is defined as 192.168.0/24, Umbrella applies policies to the traffic received from any computer or device with an IP on that subnet.

Set Up Internal Networks

• For Internal Networks with DNS-layer security deployments, register a subnet for your Umbrella Virtual Appliances (VAs) through an Umbrella Site. For more information, see Provision a Subnet for Your Virtual Appliance and Manage Sites.
• Manage Internal Networks.
