Abstract: A method of implementing controller-based distributed remote access may include connecting a plurality of edge devices to a controller via a network. The plurality of edge devices may perform hole punching to traverse a network address translation (NAT) gateway to create a NAT hole. The method may also include connecting a client device to the controller. The client device may be directly connected to one of the plurality of edge devices via the NAT hole in the network. The method may further include directly connecting the client device to one of the plurality of edge devices by receiving a query from the client device and returning public IP/ports of a most relevant edge device to the client device, the most relevant edge device being based on attributes of the client device, attributes of the plurality of edge devices, or combinations thereof.
