Thanks to all of you for the good advice.
Here is what I'm planning to...
Hopefully it is consistent with 'good practice' which I am trying to
learn.
Sorry for the length of the posting.
Let me know please if I can improve this plan in any way as
even though this is a home network I want to learn to do it right.
Thanks to you all in advance for any additional guidance.
I used .1 for both network gateways.
Since I am not subnetting 192.168.1.0 I used the standard subnet for
Class C.

Doing 'ifconfig' verifies the above settings.
But I got the following from 'netstat -nr'
[ after using 'linuxconf' to configure the two interfaces]
and 'after rebooting'...

Is this correct ?
Isn't this table telling me I've got 3 gateways?
Shouldn't I have just one gateway 'per box'? Or is that 'per
interface'?
[ I experimented with the route command once , royally screwed up, so
then unistalled and reinstalled both NICS to attempt fix it]
I'm confused about the 255.255.255.255 GenMask ?
Question... isn't 'GenMask' supposed to be the same value as 'Netmask'?
I've got the two nics installed in Box-2. I think both nics are
installed correctly.
I can ping both IP#s or hostnames ok when I'm logged in as root on
Box-2.
I have all IP#s/hostnames/aliases listed in /etc/hosts on all boxes
and 192.168.1.1 entered as the gateway for Boxes-3,4,5,
But I 'cannot ping' Box-3 '192.168.1.100' from Box-2 ,
[ I get 'from hostname(192.168.1.1)'destination host Unreachable' from
Box-2/Linux]
'or ping from Box-3 to Box-2'. [only Box-3 of Boxes-3,4,5 is connected
currently]
[I get 'timed out' when pinging Box-2 from Box-3]
[Box-3 is 'temporarily' a Win-95 box]
I'm sure I'm overlooking something here.
Any guidance appreciated. Wish I did this more often.
Also, I am not sure that I've correctly installed IPChains.
Can one of you tell me how to determine that?
IPV4 packet forwarding is enabled.
I 'really' appreciate you guidance.
Many Thanks in advance for your continued assistance.

PS: the original intent was to create a 'linux home network', behind a
linux masqueraded/firewall server, connected to the internet by a
Win-95 or Win-NT 4.0 box 'used to allow 106k downlink from ISP'.
[ using a SupraSonic Dual 56k Line Modem- 106k 'down'... 'until I get
DSL ]
PS: Charles... you didn't say 'that'... I just confused you with
another person'.
