    My home firewall is an old 486 with 20M RAM and two ISA ethernet
    cards, using an old version of single-floppy Gnat Box Light
    V3.0.3 (from It's a nice BSD-based
    firewall with NAT and SPI, ICSA-certified, configured via any of
    local, browser, or PC app (GBAdmin). However, newer versions
    require more RAM, and it's a bit clunky and difficult to

    Is there a current single-floppy Linux that will run on this
    platform, supports NAT and SPI, is easy to configure, but has
    detailed configuration if needed for port forwarding etc.? I'm
    no Linux (or other) guru.

    Alternately, is there a high quality dedicated firewall
    appliance, priced for home use (I've read a number of reviews but
    not sure if these devices are in the same class as Gnatbox)?

  2. How about:

    Quoting from the site:
    "What is Fli4L?

    Fli4l is a single floppy Linux-based ISDN, DSL and Ethernet-Router.
    You can build it from an old 486 based pc with 16 megabyte memory,
    which is more than adequate for this purpose.

    The necessary boot-disk can be built under Unix, Linux or Windows. You
    don't need any specific Linux-knowledge, but this would be useful. You
    should have some basic knowledge about networking, TCP/IP, DNS and
    routing though. For extensions and further development, that exceed
    the standard configuration, you need a working Linux-system and
    Unix/Linux knowledge."
