You can configure Branch to Branch VPN by selecting the Enable checkbox.

Branch to Branch VPN supports two configurations for establishing a VPN connection between branches:

Configuration Description
Using a VeloCloud Gateway In this option, the closest gateway is used to establish VPN connections between Edges. The VeloCloud Gateway may have traffic from other users.
Using a VeloCloud Hub In this option, one or more Edges are selected to act as hubs that can establish VPN connections between branches. The hub will be your asset and will only have your corporate data on it, improving overall security.
