Hello Leonard 

Did you get any replies to this? 

I suspect you may be experiencing issues with firewall/security group/rules issues 

Have you tried establishing hub to spoke end connectivity on each side and end to end testing by connecting using netcat?

The tunnels come up and everything is fine with one exception.  Resources deployed in Azure cannot communicate with resources deployed in Aws, and vice versa.  Both can communicate with the Openswan instance, however.  The route tables are correctly setup in AWS and Azure so I am convinced its my configuration.
