Speaking Announcement – Build a Linux Firewall

How to build a Linux Firewall… Join us and Learn!

I will be speaking at the Simi Conejo Linux Users Group (SCLug) on August 15th 2009.

I will be demonstrating how to setup a Linux based PC with multiple network interfaces to act as a firewall. The presentation will cover the following topics:

  1. Linux as a stateful firewall.
  2. Using policy based routing to select between multiple  routes.
  3. Performing source and destination network address translation.
  4. Performing load balancing between multiple internet connections.

I plan to start with a base Debian install, and take the group step by step through setting up NAT for both static and DHCP internet connections. I’ll then move to setting up a second internet connection, and demonstrate the use of policy routing to choose an outbound route for different types of connections. Once we’ve covered policy routing, I”ll finish up with session based load balancing across both connections.

If you are going to be in the East Ventura County area on the 15th, I encourage you to join us!

The presentation will be held at the Simi Valley YMCA at 2:00PM on August 15th, 2009.

I look forward to seeing you there!

— Stu
