VPN and MQTT connection – What are they?

Connectivity requirements?

If you’re looking for how the x500 IoT gateway sets up its connection, have a look at the x500 IoT gateway connectivity requirements instead.

The x500 IoT gateway can have up to 3 active connections that it uses to offer you its range of functionalities. This article clarifies the roles of these connections.

VPN connection

You are likely already familiar with the VPN connection. This is the x500 IoT gateway’s connection that enables you to remotely and safely access your machines as if you are on-site. Addionally, it’s used for Cloud Access services as well. This connection can be turned off.

Closest Lenze VPN server

The x500 IoT gateway connects to the closest Lenze VPN server, based on its location. The location is determined based on its IP address, this is called GeoIP. You can overrule this by manually entering a location and then turning its VPN connection off and back on.

MQTT connection

The x500 IoT gateway also has an MQTT connection. This is a lightweight connection that’s used for pushing a new configuration to the x500 IoT gateway or remotely switching the x500 IoT gateway’s VPN connection off or on. This connection is always active.

Additionally, if you’re using Cloud Logging or Cloud Notify, the x500 IoT gateway has another MQTT connection named “MQTT logger“. It’s used for sending data from the x500 IoT gateway to X4 remote. This connection is only active when you’ve configured Cloud Logging or Cloud Notify.
