We need a professional to help us build a private APN (Access Point Name) with our telecommunications operator, which our IoT devices will be connecting to using a simcard. It is required a VPN IPSEC Gateway and a Radius server for authentication and connection of the devices throughout the APN. We want to use the Amazon AWS services for the infrastructure of this project. The telecommunications operator’s form requires the settings of the IKE Profile (ESP Transformer, Hash Algorithm, etc.), IPSec Profile (ESP Transformer, Hash Algorithm, etc.), Subscriber IP Pool (Customer IP Range, DHCP VPN Costumer, number of parallel IP addresses), IPSec Tunnel (Pre-Shared Key, Remote Ip Address for the VPN Gateway), IPSec Policies. VPN Group (VPN Type, Topology, etc.), Subscriber IP Subnet, Radius Profile and DHCP Profile. With the VPN IPSEC we want to improve the authentication of the devices via Radius and start monitoring the traffic usage of each device connected. The task is to assist us on building the infrastructure required by the telecom. operator and help us run the necessary resources to make it work. At the end we will build a documentation of the process that was made.
