BOVPN Virtual Interfaces
For greater flexibility and networking capabilities, you can configure a Branch Office VPN (BOVPN) as a virtual interface.
You can configure a BOVPN virtual interface tunnel between any two Fireboxes that run Fireware v11.8 or higher.
In Fireware v11.11 and higher, you can configure a BOVPN virtual interface to a third-party VPN endpoint with the GRE tunneling protocol. In Fireware v11.12 and higher, you can configure a BOVPN virtual interface to a third-party VPN endpoint or cloud-based endpoint without GRE. Supported endpoints include cloud-based virtual networks like Microsoft Azure, and Cisco VTI endpoints.
