title: AzureRM site-to-site Connections status is "Unknown"
body: <p>First, I followed the instruction <a href="https://azure.microsoft.com/en-us/documentation/articles/vpn-gateway-howto-point-to-site-rm-ps/" rel="nofollow">here</a> to create a point-to-site VPN. Then I created a site-to-site VPN to my local network on the portal UI. My on-premises VPN gateway device is Dell Sonicwall SOHO running SonicOS Enhanced 5.9.1.4-4o. The settings of the Sonicwall router is shown in <a href="https://drive.google.com/open?id=0B0pjlQ4JEOiJdDZaaTA3TnIySjg" rel="nofollow">this document</a>.</p>
  
  <p>I am able to connect to the VNet via P2S but I couldn't ping the VM. The site-to-site connection status shown is "Unknown" instead of "Connected" or "Not Connected". I tried to search for the meaning of "Unknown" status but I couldn't find any clue. Does anyone have any idea ?</p>
  
  <p>Thanks,
  CK</p>
