Welcome to the NetBSD/i386 Firewall Project
``Of course it runs NetBSD.''

NetBSD/i386 Firewall is a free firewall solution for people with a permanent Internet connection. This includes most users of cable or ADSL services, but also businesses with leased lines. PPPoE support and PPTP support is available on CD.

  • Any old PC will do. If you have an old PC left over, with a 80486 or more recent processor (including Pentium processors), with 8 MB of memory, any old harddisk and two ethernet cards, you have enough!
  • Easy install. The standard NetBSD install has been extensively modified to make install as simple and straightforward as possible, and it is geared towards people who have no Unix knowledge and do not intend to get any.
  • Stability. It is based on NetBSD, one of the most stable platforms for the PC. Install it, stick it in the basement behind the stairs, and never look back.
  • Extensible. The base system is kept as lean and mean as possible, but there's plenty of room to add services, such as your own mail and web server. We also expect to make a 'Pro' version available that has many of these services built in.
  • Free. NetBSD is a free operating system, and therefore so is this firewall project. If you're an experienced Unix system administrator or programmer, we have the sources available for download as well, and those too are free. If you're happy with the firewall, you can optionally donate some money, or order the installer and firewall software on CD. The CD has a lot of other goodies as well. Check out our CD and Donations page.
  • Support your home network. All computers on your home network can use it, without having to buy anything extra (well, perhaps some network cabling). Of course, if you own a small company, that works just as fine.


NetBSD/i386 Firewall is based on NetBSD, a free highly portable UNIX-like operating system available for many platforms, from 64bit alpha servers to handheld devices. Its clean design and advanced features make it excellent in both production and research environments, and it is user-supported with complete source. Many applications are easily available.
