Guess you have hundreds of police cars, each with a MK2, and all have identical configuration. You can use bulk configurator for zero touch deployment, and low skill personal are able to replace defect devices without configuration. If someone wants to access the dashcam inside a car from the headquarter you need to have the ip adress to acess it over PAT. While the NAT-Mode-MACAdress is build from parts of the serial number we can create reservations for every car (router) on the Hubdevice. Currently this is only possible with a Balance as the hub device. There is no configurable DHCP service for NAT-Mode on fusionhub.
