You might find this interesting... 

At home I use Linux Router Project (LRP). Everything you need fits on a
floppy so a hard drive is not needed. I have a DHCP server, PPPoE client,
bind, ipchains, etc. all loaded at boot time. 

You can find more information about it at www.linuxrouter.org.

Subject: building a firewall

Hi!

I just got an old 486-based evaluation board with the following
stuff on it:

- 100 MHz 486
- 32 MB DRAM
- 24 MB flash
- 128 kB SRAM
- two network interfaces (no idea of the driver in NetBSD)

I'd like to build my own firewall from this box, the only question
is how can I produce the image which is transferred to the flash
memory. I realize the image must contain the kernel and some
memory filesystem (or could I use part of flash?) for the needed
utilities like dhcpd and ipf.

But how can I create such images? I guess the INSTALL_* floppies
are similar to what I need, but are there any tutorials or
step-by-step introductions for doing embedded systems with NetBSD?

I'm a novice in this area so please don't assume anything...

Martti
