Meet My Home Firewall

Over time I’ve been asked to please post about the hardware I use at home. Depending on the season I may be running either pfSense or M0n0wall(currently). This set-up has been running for over a year without problems.

The Hardware:

  • VIA C3
  • 512MB RAM(Kingston)
  • 2 10/100 NICs
  • 16MB SD Card / USB SD Reader
  • Serial Port(does not work with M0n0wall)
  • Same PSU that came with the case

As you can see I am using the case of a Dell Optiplex to house my firewall.

The entire installation runs from a 16MB SD card connected to cheap USB reader. Where do you get a 16MB SD card you ask?, it came with my digital camera. It takes around 90 seconds to boot M0n0wall from this set-up.

The onboard Serial port does not work when M0n0wall is installed, I don’t have the time to troubleshoot the reason why this only happens with M0n0wall(works with pfSense). BTW: The board is a Gigabyte that I bought off some guy in a van, seemed legitimate at the time.

Not pictured is the noisy PSU and missing 40mm fan necessary to cool the VIA C3. Not what I would call quiet.

The system is capable of handling a 12Mbps Internet connection with resources to spare.

Nothing new or ground breaking. But I have been thinking about replacing the firewall with either an ALIX or a RouterStation Pro(quiet), which would be a good topic for another post. In the mean time, I am more than happy with my current set up. If you have any questions leave a comment below.

Don't Trow Away That 16MB SD Card

Use it to run Monowall an embedded firewall that is available in a 8.53 MB(.img) image. Specifically, I opted to download the generic-pc-1.33.img image which can be used on CF/HD/USB drives and works on my VIA C3 firewall.

And if you are wondering how in this day and age any one could get hold of a 16MB SD card, well let me you that it came with my Canon digital camera. BTW, I am working on a post titled: How To Install Monowall From A USB Drive.
