Data transmission on the network of Informatics Engineering Research Laboratory Universitas Ahmad Dahlan using an unsecured public internet network, in order to be able to access the network from crossing actions and search for data traffic. One solution that can be done is with Virtual Private Network techniques using OpenVPN in learning networks. This research describes attempts to make a Virtual Private Network using the OpenVPN network design in the research laboratory of Informatics Universitas Ahmad Dahlan and how big the level of security. The results of implementing Virtual Private Network using OpenVPN is that the attempt gives a positive result, this is evidenced by the sniffing of data that cannot detect the username and password sent. Quality of Service measurement results experienced a decline in network quality with delay parameters rising from 51.4 ms to 463.4 ms, packet loss rose from 7.8% to 20.2%, throughput dropped from 82.8% to 71.6%, and bandwidth dropped from 64786.6 bit/s to 55589 bit/s, it is due to the encryption process and encapsulation that takes time.
