The Windows Azure team announced last friday new capabilities for cross-premises connectivity between Windows Azure and your on-premises, including the support of software VPN devices to create Site-to-Site VPN connections. With this new capabilitiy now you can use a plain Windows Server 2012 with RRAS (Routing and Remote Access) enabled to create the VPN connection with your Windows Azure Virtual Network instead of use a hardware VPN device (you can also use a hardware VPN device is you prefer it).
