Azure Hub and Spoke topology
As is shown above with Hub and Spoke topology, does it support multiple NVA's in the Hub vnet and force traffic to traverse through them (one by one)?
In my test, multiple NVA's work when everything is in the same vnet.
When you put client and server in two separate Spoke vnet's, you can only see traffic hit the first appliance, and then off the radar after exiting it, but then arrives at the destination in the other vnet.
