PsygNAT - free firewall and NAT router tool on a floppy!

Contributed by sean on from the openbsd on the most unreliable of mediums dept.

PsygNAT is a free firewall and NAT router tool for i386 which boots off on a single floppy.
It is based on the OpenBSD kernel and therefore, uses pf as its native ruleset management.

PsygNAT contains the necessary tools in configuring a simple NAT router, a stateful (and
transparent) firewall, or a bandwidth limiter via ALTQ. It supports both static and
dynamic client setup. It also includes mg, an emacs-like text editor, which can be used
to write firewall and network address translation rules.

    Sounds nice.
    Some information about what version of OpenBSD is used would be cool.

      http://www.shockley.net/obsd-bootcd.asp has instructions on how to make a bootable .iso using a bootable floppy image and mkisofs, it should be adaptable to your situation.

    Yes, like fdgw, just based on OpenBSD. I was looking for this some time ago. Gotta check it out!

    I noticed in the config file on his website he has a NO_PROPOLICE option defined. Why is that? Is that because of performance, floppy disk space contrataints, or something else? check it out un the url pasted above.

      its due to space constraints, it is only limited to 1.44mb (both kernel and userland)
