Paranoid Penguin - Building a Transparent Firewall with Linux, Part I
But, that will have to wait until next time. Hopefully, you now understand the difference between a standard, routing firewall and a transparent, bridging firewall. In my next column, I'll sketch out an example usage scenario (conceptually very similar to the network in Figure 3), describe a couple different approaches to selecting Linux firewall hardware and begin showing how to configure a transparent firewall, starting with bridge/switch setup. Until then, be safe!
