Mobile computing devices, industrial control sys-tems, and service provider clouds need to be connected toeach other over wide area networks. However, reliability,quality of services and confidentiality are challenging in suchsetups. Moreover, isolated appliances and physical equipmentface harsh environment conditions. While application specificgateways can be more secure alternative, their time to marketis typically high, and things will be done with insecure ad-hocsolutions. In this paper we explore designing secure layer 2 overlay networks using Software Defined Networking (SDN), and challenges in implementing them with open source tools.
