Here's what you will need to know for a base
install:

Will the CD boot? (if not, create the boot floppy)

Are the NIC's PCI based? (if not, you'll need to set
them up first)

Boot the CD.

Let it format the HD and install itself.

Let it find the NIC's or Modem/NIC.

Configure the GREEN NIC, ie: What private subnet
will you be using. A common one would be
192.168.1.1.

Configure the RED Nic with a style, ie: does it get
it's address via DHCP, Hard Coded, etc?

Set up your internal DHCP address range. A
common range would be 192.168.1.200 -
192.168.1.239

Set up all of your passwords for different access
types, ie: Admin, Setup, Root.

Take out the CD and Reboot.

Now, go to one of your internal machines and
reboot it. Assuming it is using DHCP, it will pick up
an address from the new IPCop created subnet
automatically. Run either ipconfig in DOS or
winipcfg, depending on your windows version to
see if you got an address in the DHCP range you
assigned above. If so, your internal subnet is ready.

If you're on a cable modem, you may already be on
the internet, but if you have ADSL or a modem,
there is a little more setup.

Aim your windows web browser to the ipcop
address at: http://192.168.1.1:81

You should see the IPCop admin page. Press the
Dialup tab on the left. It's going to ask you for your
admin login. The user id is admin and the password
is whatever you set up in the install step 5 minutes
ago. Select the correct COM port, or PPPOE for
ADSL (probably). Set up the user id's and
passwords. Press the SAVE button at the bottom of
the screen.

Click the Home button on the left. Press the Dial
button.

There ya go. I've installed IPCop in 6 minutes from
the time I booted the CD to being on the internet on
a cable modem.
