Add Virtual Interface The virtual network interface allows you to configure a new interface such as a VPN tunnel that encapsulates data inside a transport protocol. The supported tunneling protocols include GRE, L2TP, PPP, and PPtP. The virtual interface can be created for other reasons, such as to configure a relay bridge to extend the wireless network. Note: Adding a virtual interface may require modifications to the load balancer configuration. For load balancer configuration, see Load Balancing.
