Linux For those that don't already know, smoothwall is a very slick and easy way to setup a firewall/nat/dhcp server (and more) at home or in a small office very quickly even on old computer equipment. I have used Smoothwall 1.0 in the past and liked its features (although at the time, I did have a problem with Snort failing to start after I updated the software with some fixes...). It served on an old Pentium II 400mhz machine with two NICs inside (network cards). One was the 'green' interface (more about that later) and the other was the 'red' interface. I used that setup for quite a few months, mainly because I wanted to see what alternatives there were to hardware based firewalls (such as DLink gateways/firewalls) that I had been using.

For home use...

These PC based firewalls are cool to play around with, but for home use I think a Linksys/Netgear firewall router is often times going to be a perfectly suitable choice. A computer (even an old one) wastes a lot of electricity and generates a lot of heat and noise.

I use to have a PII 233MHz Linux "server" setup that I used for various things such as a firewall/nat/ftp/file server/samba/etc... That didn't feel like quite as big of a waste since I was doing various things with it. But even still 95% of the time it's only task was to direct traffic from my LAN to the Internet. I just couldn't ever get it out of my head how much power was being wasted by that computer so I bought a Netgear router and retired the server. I'm sure the money I spent on the Netgear router/firewall ($40 I believe) has long since paid for itself in power savings.

Granted though, some people are going to need something more than a Netgear router (like the guy in the article pointed out - his needs exceeded the capacity of his router).
