Course Description

This course explores firewall fundamentals, rules, filters, design strategies, and deployment best practices. Students also learn about virtual private networks (VPNs) for secure remote access.

Two key technologies for protecting a network are firewalls and virtual private networking (VPNs). This four-lesson, web-based course steps through pfSense Firewall configuration on a client and server and VPN configuration. The course offers textbook chapters, lectures, and virtual labs that duplicate real-world scenarios. Qualified instructors are available to answer questions about the content and theory.

To begin, you will learn how to configure pfSense Firewall to protect a client computer by answering a set of configuration questions and then implementing the configuration choices you made. Next, you will configure pfSense Firewall to protect a server using steps similar to the ones you used for a client computer. Then you will configure the server side of the Linux Debian Openswan VPN. Finally, you will configure a Windows Server 2008 machine as a VPN client to connect to a Linux Debian Openswan VPN. Then you will use the Wireshark protocol analyzer to look at the tunneled VPN traffic using the IPsec protocol, and compare it with the non-tunneled traffic.
