PC based routers like Smoothwall

Yup, there are a few notable distributions of compact, linux or BSD based firewalls floating around.
www.freesco.org is the one you'll see mentioned the most around here.

There is also the Linux Router Project (LRP) and a few offshoots from that. It's a single floppy disk based linux distribution which is just cool imho. 🙂

If you check out www.freshmeat.net they track all sorts of *nix/*BSD related software and they do list some of the lesser known distributions.

I believe Freesco and Smoothwall are the most popular and smoothwall sure looks like it has a great interface. Let me know if you find any other notable ones!

Thanks,
Gaidin

Edit: Some of the ones I've been thinking of trying out are Devil-Linux and emBSD. Devil-Linux is a small (<50MB) linux distro that runs off CD and stores custom config files on a floppy disk. It's not inherently a custom firewall but it can be used for such a thing. emBSD (I think that's the spelling) is a super stripped down version of OpenBSD for embedded devices and can fit on a 32 meg flash memory card...A hard drive will eventually fail but the flash memory should last for a LONG time and will help keep the firewall/router up at all times. I've already got my compact flash to IDE adapter ($20!) and will hopefully get a chance to try it out sometime soon. 😉
 
Ah, ok thanks Gaidin!

When I am a little more awake (its 03:40 here.. (AM)) I will take a look at some of those sites and get back to you 🙂

Thanks!
 
I personally wouldnt use anything but OpenBSD. Just personal preference, there may be and there may not be technical reasons behind it. 😉

I managed to comfortably fit OpenBSD (without x since this was a firewall) on a 245.35MB hard drive. I think it even had the src on there.. (got the hard drive sitting here unused right now 😛). Ive also read articles on slimming it down to fit a 128MB flash card. Ive never tried the emBSD, but I also know many of the developers (well Theo anyhow) doesnt really care about embedded type work for OpenBSD.
 
Thanks all for the replies, they are much appreciated.

I shall get back to you all when I have had sufficent time to explore the goodies you have pointed out to me 🙂
