The controller that is capable of acting as a STUN (Session Traversal Utilities for NAT) server during the onboarding process of Edge devices is the vBond controller.
vBond controller is a central point for secure connectivity between edge devices and the overlay network. It is responsible for initial device authentication and registration, as well as for the distribution of information about available controllers in the overlay network. During the onboarding process, the vBond controller assigns an IP address to the Edge device and facilitates secure communication between the Edge device and other controllers in the network.
STUN is a protocol used to assist in the traversal of network address translators (NATs) or firewalls for real-time communication protocols such as voice over IP (VoIP). During the onboarding process, the Edge device may be behind a NAT or firewall that could prevent it from communicating with the vBond controller. In this case, the vBond controller can act as a STUN server and assist in the traversal of the NAT or firewall, allowing the Edge device to establish a connection with the vBond controller.
vSmart controller is responsible for controlling and distributing policies to the Edge devices, while vManage controller provides a centralized management interface for monitoring and configuring network devices. PNP (Plug and Play) Server is responsible for automating the deployment and configuration of network devices. However, none of these controllers are capable of acting as a STUN server during the onboarding process of Edge devices.
