ARM600 is typically installed in the same location as the central control and monitoring system.
When typical SIM cards are used, ARM600 requires a fixed line Internet connection with a public and static IP address. The public IP address is required for the data from the connected Arctic 600 series wireless gateways to be routed to ARM600 via the public Internet. The fixed IP address is required because the data connection between the Arctic 600 series wireless gateways and ARM600 is initiated by the wireless gateways.
Use of a private APN is recommended. The cellular operator’s access router provides routing between the IP addresses of the SIM cards and the M2M gateway.
The added value of ARM600 in a private APN use case comes from the added security, end-to-end routing from central LAN to remote LAN and centralized device management.
ARM600 in the company’s DMZ
The DMZ is a safe subnet, separated by firewalls from the company LAN and from the Internet. The servers requiring accessibility from the Internet are placed in the DMZ. The company’s border router/firewall forwards the VPN port from the public IP to ARM600, which has a private IP address and uses the border router as a default gateway.
ARM600 behind the company’s firewall
In this setup ARM600 is directly connected to the company’s LAN. ARM600 has a private IP address and the border router/firewall forwards packets from a public, static IP address to ARM600.
ARM600 directly connected to the Internet
In the simplest scenario, ARM600 is directly connected to the Internet, that is, the public, static IP is configured to the WAN interface of ARM600. ARM600 itself works as a firewall and border router in this case.
