Virtual private networks (VPN) are used by remote clients to securely connect to company networks. This research discusses the performance of two different VPN configurations to determine their impact on a company's data communication network. The network configurations for this model are typical real-world networks complete with geographically diverse business office locations, a company headquarter, and a separate data warehouse location. The effects of the two VPN configurations are then tested using the academic version of OPNET IT Guru network simulation software. Analysis of the data collected from the simulations show the different network performance that results from the use of alternative VPN setups. Managerial recommendations are made based on the results of this analysis.
