Gnatbox Light single floppy firewall replacement?

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 http://www.gnatbox.com). 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
configure.

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)?

How about:
http://www.fli4l.de/english/e_fli4l.htm

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."
