(Nearly) full tickless operation in 3.10
So, Linus is not even behind seven proxies? What poor security!
Memes aside, I have to ask professionally: why is three firewalls better than one? Or, should I worry that I only have one firewall?

It is hard to tell whether this is actually worthwhile or an unnecessary expense.

I have a firewall in my adsl gateway protecting my "insecure" network. The insecure network has wifi/games consoles/set top box network/guest access.
I have a firewall between this insecure network and a wired only network with the machines I care about.
Most of my machines have a software firewall as standard making for a third level of firewall.

You cannot put a firewall around wireless which is why wireless networking requires encryption and authentication. It is also why you do not let your wireless network inside the firewall of wired machines "you care about".

Yeah, it gets complicated.

You use two firewalls to create a DMZ which is of course a pretty typical setup.
Add a personal firewall on your own machine (again, a standard security recommendation) and presto--you have three firewalls.
