Azure VPN Routing issue

$

Hi

 

We are trialing S2S VPN between Azure and AWS using Windows 2012 RRAS.  We have been able to establish connectivity from RRAS box and Azure VM but it cannot route beyond this point.

 

Configuration info

Azure network: 10.0.0.0/8

Subnet-1: 10.0.0.0/11

Gateway subnet: 10.32.0.0/29

Azure VM IP: 10.0.0.4

 

Local Network: 172.16.0.0/16

Subnet: 172.16.10.0/24

 

RRAS

One interface with private IP: 172.16.105

Elastic IP assigned to the same interface

Ran the VPN device script successfully after one restart

Demand dial-in interface showed up (Connected)

 

  • Azure VNET dashboard shows that VPN is connected and RRAS demand dial-in interface is up.  
  • RRAS residing on AWS and Azure VM can "ping" each other fine
  • RRAS is connected to the internet
  • RRAS can route other VM's traffic out to the internet using NAT
  • VM on AWS cannot ping Azure - the VM is located on the same network as the RRAS VM

 

 

Any more info required let me know.
