A Virtual Private Network is a wide spread technology for connecting remote users and locations to the main core network. It has number of benefits such as cost-efficiency and security. SSL and IPSec are the most popular VPN protocols employed by large number of organizations. Each protocol has its benefits and disadvantages. Simultaneous SSL and IPSec implementation delivers efficient and flexible solution for companies’ with heterogeneous remote connection needs. On the other hand, employing two different VPN technologies opens questions about compatibility, performance, and drawbacks especially if they are utilized by one network device. The study examines the behavior of the two VPN protocols implemented in one edge network device, ASA 5510 security appliance. It follows the configuration process as well as the effect of the VPN protocols on the ASA performance including routing functions, firewall access lists, and network address translation abilities. The paper also presents the cost effect and the maintenance requirements for utilizing SSL and IPSec in one edge network security device
