I am no longer utilizing the R10 and transitioned over to another router. I’ve since restricted all WAN access with the exception of NTP to all Alta devices on the network.
Alta Control
Alta AP
Alta S16
Alta S24
After a week, I temporarily restored WAN access for testing and discovered the RSA key along with the original configuration on the Control had vanished shortly after restoration and required to be modified again. Clearly this shouldn’t have occurred since this is a locally managed network.
Additionally, there are no options on your GUI to point a respective Alta device to an internally hosted NTP server without adjusting in the syntax. For example, if let’s say I wanted to point all devices to the respective gateway that is hosting NTP. Note the export below for the Alta Control shows the server name, but has the wrong date. All other Alta devices are showing accurate NTP information.
