Can you use the same RRAS server for multiple concurrent VPN connections to Azure?

During a recent presentation on Integrating the Microsoft Cloud with Your Environment (from http://forms.windowsitpro.com/Building-Your-Business-Cloud-Agenda), there was an excellent question which was asked that I tried yet. Specifically they asked “Can you use the same RRAS server for multiple connections?” My initial thought was that this should work, but I wanted to test it out.

To establish this test, I had an original configuration shown below in a functional state.

I added a second Virtual Network connection in Azure, downloaded the configuration PowerShell script (after the gateway was created) and ran it on the RRAS server.

The resulting design now looks like the following:

The screenshot below shows the Azure configuration for the original VPN connection (after the VPN connection was successfully established).

The screenshot below shows the Azure configuration for the second VPN connection (after the VPN connection was successfully established).

The following is the RRAS configuration after running with the second VPN configuration script:

 

Below shows the trace to the original network from the RRAS server:

Below shows the trace to the new network from the RRAS server:

Summary: Can you use the same RRAS server to connect multiple VPN sessions to Azure? From my tests the answer to this looks like yes you can!
