OpenVPN Access Server is a full featured SSL VPN software solution that integrates OpenVPN server capabilities, enterprise management capabilities, simplified OpenVPN Connect UI, and OpenVPN Client software packages that accommodate Windows, MAC, Linux, Android, and iOS environments. OpenVPN Access Server supports a wide range of configurations, including secure and granular remote access to internal network and/ or private cloud network resources and applications with fine-grained access control.

An OpenVPN Access Server deployment consists of one server, many clients and many users, as depicted in Figure 1. Each client machine in this topology uses the public IP network (the Internet) to communicate with the OpenVPN Access Server and thereby gains VPN-protected access to the private IP Network connected (if present).

If adequate licenses are not available in the OpenVPN Access server, then the users will not be able to connect to the Private IP Network. Also sometimes, a particular user may hog the bandwidth of the network by transmitting/ receiving large chunks of data through the server. It is therefore imperative that the OpenVPN Access server is monitored periodically for assessing the license utilization and the user details. This can be achieved using eG Enterprise.
