Virtual Private Network (VPN) settings

Virtual Private Networks (VPNs) are used to securely connect two private networks together so that devices may connect from one network to the other network using secure channels.VPN uses IP Security (IPSec) technology to protect the transferring of data over the Internet Protocol (IP). All Digi Cellular Family products except Digi Connect WAN support VPNs.

The Digi device is responsible for handling the routing between networks. Devices within the private network served by the Digi device can connect directly to devices on the other private network to which the VPN tunnel is established to. The VPN tunnels are configured using various security settings and methods to ensure the networks are secured.

Uses for VPN-enabled Digi devices

VPN-enabled Digi devices, such as Digi Connect WAN VPN, are cellular-enabled routers that securely connect remote subnets using IPsec VPN technology. Devices in the Digi device’s private network can connect directly to devices on the other private network with which the VPN tunnel is established. You configure VPN tunnels using security settings and methods to ensure the networks are secured.

The Digi device is used for primary or backup remote site connectivity. Secured IPsec VPN traffic is typically routed from the Digi device over the cellular IP network and is terminated by a VPN appliance at the host end.

A VPN-enabled Digi device can be used in several scenarios; for example:

As the primary remote site router where no other WAN router is used.

As a backup router where the remote site has a primary WAN connection through DSL, Frame Relay, or other means.

To provide secure access to remote serial and/or Ethernet devices.

This section describes using a Digi device as a primary remote site router using IPsec Encapsulated Security Payload (ESP) and Internet Key Exchange (IKE)/Internet Security Association and Key Management Protocol (ISAKMP) pre-shared key methods.

X4, X8, X2 specifications

Digi X2 and X1 are advanced cellular IoT (Internet of Things) gateways that provide an innovative solution for industrial applications, smart cities, and remote asset management. Both devices equip users with the means to connect, monitor, and control a wide variety of assets without the limitations traditionally imposed by wired connections.

Digi X2, designed for complex IoT demands, features dual SIM slots which ensures uninterrupted connectivity through automatic failover. This makes it particularly valuable for critical applications where connectivity is non-negotiable. Additionally, the X2 is equipped with LTE-M and NB-IoT support, enabling extensive coverage in areas where other networks may struggle.

On the software side, the Digi X2 supports Digi Remote Manager, a powerful tool that allows users to monitor, manage, and deploy devices remotely. This cloud-based management system simplifies the overall management of IoT devices by providing real-time insights, easy configuration changes, and over-the-air updates, saving both time and resources.

In contrast, the Digi X1 serves as an entry-level model that balances performance with cost-effectiveness. It supports LTE connectivity, providing a reliable connection suitable for a variety of applications. The X1 also offers seamless integration with existing networks, allowing users to leverage their current infrastructure while expanding their IoT capabilities.

Both Digi X2 and X1 are designed with ruggedness in mind, making them suitable for deployment in harsh environments. They are engineered to withstand extreme temperatures and vibrations, ensuring reliability even in demanding industrial settings.

Another notable characteristic of these devices is their extensive input/output (I/O) capabilities, which enable them to interact with sensors, machines, and other types of devices. This versatility allows for a broad spectrum of applications, from monitoring temperatures in remote locations to tracking assets across geographic boundaries.

In summary, the Digi X1 and X2 provide robust, reliable, and scalable solutions for modern IoT implementations. With their advanced cellular connectivity, cloud management capabilities, and durable design, they are poised to enhance connectivity across industries, driving efficiencies and enabling smarter operations. Whether for critical industrial applications or efficient asset management, Digi's offerings are tailored to meet the diverse needs of today's IoT landscape.
