Software Download

Simple Instructions

Advanced Instructions

Hardware:

Step 1
Identify The Hardware

You have verified that you have at least a 486DX whatever.
You have at least 16mb ram.
NIC #1 is ??? ie. 3COM509b IRQ 10, 300, server
NIC #2 is ??? ie. 3COM509b IRQ 11, 310, server

Step 2 Assemble Hardware

Install both NIC's in your 486.
If you have an OS on your hard drive, boot up to see what the cards autodetect as. If there are no conflicts you may be able to skip step 3
Remove the hard drive, or at least unplug the hard drive cables. Unplug the case fan.

Step 3
Setup NIC

Use whatever DOS utilities to determine the NIC parameters
ie. With 3com you can turn off PNP if needed, set the IRQ and Address, optimize for server use






Floppy Disk Preparation

Download Software

Look under "Read and Heed" (dachstein-v1.0.2-1680.bin)
Download it to your home directory.

Think of a Name

You want a snazzier name than "firewall" don't you?

Format 2 Floppys

Open a shell window. Insert disk into floppy drive.
Type: fdformat /dev/fd0u1680 Repeat for second disk.
Label first disk "firewall name", http://192.168.1.254, working copy.
Label second disk "firewall name", http://192.168.1.254, backup copy.

Burn One Floppy

Insert your working disk.
Since you have a shell open at your home directory where you
downloaded the software too, all you need to type is:
dd if=dachstein-v1.0.2-1680.bin of=/dev/fd0u1680




Configure Firewall (incomplete)

Caveat

The save step saves to the ram disk. The backup step saves to the disk

Boot

Insert your working disk and boot.

Login

As root. Password not yet required

Edit

Menu item 3, then 3, then 1. Uncomment (delete the #) the modules needed for your NIC's. ie. 3COM 3C509b is 3c509.
