Many of you have noticed the upgrade of your CenturyLink Cloud Client VPN service, which allows you to connect to the secure network that contains your servers and resources. Read on to learn more about the service and the enhancements made with this update.

Overview

Client VPN enables users to connect to their secure isolated network. Each account has its own isolated VPN service provided at no charge. This built-in service is managed by CenturyLink Cloud’s highly trained network operation center. If you have any issues please look at the status system or contact support.

To complete the Client VPN initial configuration, simply download the certificate—used when connecting to the VPN service—or complete the two-factor authentication that we’ve linked to below. To learn more about ways to connect such as persistent VPN connections or direct connections please go here.

Current Limitations

There are only a few limitations on this service as it is based on the OpenVPN project.

  • Maximum concurrent users: 20 (if you need additional users, please contact support)
  • Maximum connection: 1Gbps

Performance and Tuning Enhancements

We’ve made a host of performance and tuning enhancements to the Client VPN service that will result in a better user experience. We decreased CPU utilization on each unique instance from 80% down to ~7%, or roughly 1/10th the CPU usage, through the use of an updated kernel, VMware tools, and OpenVPN packages.

We also made changes to the instance that should increase network performance as well as allow the VPN servers to recover in the event of storage latency.

Now More Support!

You can find new documentation that we’ve added our knowledge base for troubleshooting, configuration, running multiple VPN connections, as well as the two factor authentication guide.
