The SecureEdge Manager allows administrators to configure DNS Interception on Sites and Private Edge Services. Some of the key features of DNS Interception are:
It intercepts and replaces DNS queries matching the configured domains.
It enables Sites and Private Edge Services to respond with custom DNS entries.
You can the add an IP address from either a public or private range. This IP address must be resolved for specific domains within the connected LANs.
There is no need for the IP address to be unique either on the Site/Private Edge Service or in the selected workspace.
By default, DNS Interception is disabled for existing or new Sites/ Private Edge Services.
There is no limit to the number of domain/IP mappings.
You can add, edit, and delete domain/IP mappings. In addition, you can remove all of them to turn off DNS Interception.
Currently, the DNS Interception configuration is not supported on Azure vWAN or on Barracuda hosted Edge Services.
