In order to manage a ReadyLinks device through ReadyView, it must be able to communicate with the ReadyLinks cloud over a secure tunnel. This tunnel is created between ReadyLinks devices and dashboard to pass management and reporting traffic in both directions.
Because the dashboard is located on the public internet, the tunnel is always initiated outbound from the managed device. Once a connection is established, the device maintains the connection by occasionally sending packets and receiving a response. When a firewall or gateway exists in the data path between the managed device and the dashboard, certain protocols and port numbers must be permitted outbound through the firewall for the secure tunnel to function.
