The CloudVPN router can have up to 3 active connections that it uses to offer you its range of functionalities. This article clarifies the purpose of these connections.
The CloudVPN router will be shown as "online" when at least 1 of these connections is active.
You are likely already familiar with the VPN connection. This is the CloudVPN router's connection that enables you to remotely and safely access your machines as if you are on-site. Additionally, it's required for any HTTP/VNC services to work. This connection can be turned off.
The CloudVPN router connects to the closest CloudVPN 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 switching its VPN connection off and back on.
The CloudVPN router also has an MQTT connection. This is a lightweight connection that's used for pushing a new configuration to the CloudVPN router, upgrading its firmware, or remotely switching the CloudVPN router's VPN connection off or on. This connection is always active.
Additionally, if you're using Cloud Logging or Cloud Notify, the CloudVPN router has another MQTT connection named "MQTT logger". It's used for sending data from the CloudVPN router to the CloudVPN Portal. This connection is only active when you've configured Cloud Logging or Cloud Notify.
