Hi,

I have couple of concerns related to Azure Virtual Private Network gateway:

  1. Is there any possibility to access or connect multiple sites from a single Vnet?
  2. I have deployed a policy-based VPN gateway and sometime the tunnel not working as expected. I'm not getting any error, but the tunnel is going down, is this an issue with my configuration?

    Hi @NSA

    In response to your questions,

    1. You can connect to multiple sites by using Windows PowerShell and the Azure REST APIs. Please refer the document: Hosting multiple sites by using Vnet to Vnet.
    2. The behavior is expected for policy-based VPN gateways. When the traffic over the tunnel is idle for more than five minutes, the tunnel is torn down.

    When traffic starts flowing in either direction, the tunnel is re-established immediately. Please refer the document.

    I hope this has been helpful!
