Hi all,
i have a network HUB & Spoke where i have a vMX in Azure and a private DNS also in Azure. I have an ENTERPRISE LICENSE)
If an user is connecting from a spoke....the flow should be as indicated here below:
 
+---------------------+
| PC VLAN 1001 |
+---------------------+
|
+---------------------+
| Spoke Meraki MX |
+---------------------+
|
==========VPN==========
|
+---------------------+
| Hub Meraki VMX/Azure|
+---------------------+
|
+---------------------+
| DNS VM (privato) |
+---------------------+
| |
[local] [pubblica]
| Forward
| |
[risponde] [Umbrella DNS Cloud]
 
 
 
So, the Private DNS is used for local services (servers in the cloud), while all other requests will be forwarded to Umbrella.
Now, since Umbrella will receive all DNS requests coming ONLY from the vMX public address in Azure, should I purchase just one license, or do I need to consider the number of users who will be using that DNS concurrently? Any idea on how this should be handled?
