This really depends on what type of firewall software you want to use. I don't know from personal experience but it seems to me a lot of DIY firewall junkies like to use LINUX on their dedicated firewall box so obviously there are some aplications for that OS. I am sure there are others (firewall apps) for Windows, etc.
So I suggest you settle on the firewall you want to use first and then install the OS on the third box accordingly. Again, sorry I can't be more specifically helpful. Maybe a firewall guru will drop in on this thread.
