How would you go about doing that you might ask, well I’ve got the solution for you: IPCop!

What is IPCop?

IPCop is a secure Linux distribution managed through a web-interface. It turns an old PC into a firewall and VPN gateway. Features an Intrusion Detection System.  Check it out at http://www.ipcop.org.

What are the hardware requirements for IPCop?

I ran IPCop on an old system I had lying around.  Specs:

  • Pentium 2
  • 320MB PC100/133 RAM
  • 20GB HDD (Overkill, but the smallest I had)
  • 2 NICs
  • ATI Rage 8MB Video Card *
  • CD ROM *
  • Cardboard and packaging tape (to keep as much cat/dog hair out as possible… and for STYLE!)

* Only needed for install

The actual requirements are pretty low.  You probably only need a 2-5GB hard drive, smaller if don’t plan on keeping any logs.  Also, if you’re not planning on running the intrusion detection system, you could get away with 64MB of RAM easily.

Hardware Firewall Running IPCop

Where do I get it?

Go to http://www.ipcop.org and choose “Download” from the menu on the left.  This will forward you to a SourceForge page.  Find the latest version and download the .ISO file.  You will then have to use some CD burning software to burn the .ISO as a bootable CD.

How do I install IPCop?

IPCop couldn’t have been easier to install.  You just pop the CD you burned in the last step into your CD ROM drive and boot the computer.  Make sure your computer is set to boot from the CD drive first, otherwise this wont work.  Once the install CD boots, just follow the on-screen instructions.  Most of the options are pretty straigt forward, if you’re at all confused about any of it, refer to the documentation found here: http://www.ipcop.org/index.php?module=pnWikka&tag=IPCopDocumentation

Also, this episode of Systm was a great resource: http://revision3.com/systm/firewall/, I highly recommend checking this out before you start your project.

Got anything else?
