Network Numbering Problem, 3-4 nics instead of Hub

Hallow all,
I have a network numbering/routing question.
I have a pretty standard home network with a linux
firewall/NAT box feeding a
hub to what is is usually 3-5 machines.
Can I eliminate the hub and use 3+ nics on the
firewall box and
'how' would I number them???
I have set this up once before but I find that
the various hosts connected to the firewall can not
see or access each other, but all can access the net.
what am I doing wrong below ?
Internet==> firewall/NAT Machine [with multiple Nics
and CrossOver CAbles to Hosts] ==>
==> eth0 [ 10.0.0.1/255.0.0.0] ==>
host-1 eth0= 10.0.0.2/ 255.0.0.0
==> eth1 [ 172.16.0.1/255.255.0.0] ==>
host-2 eth0= 172.16.0.2/255.255.0.0
==> eth2 [ 192.168.0.1/255.255.255.0] ==>
host-3 eth0= 192.168.0.2/255.255.255.0
The method above did now allow each host to see &
access each other, they could access the internet.
Could the following Alternative Numbering Work ??
Internet==> firewall/NAT Machine
[with multiple Nics and 'CrossOver Cables'
to 'multiple' Hosts] ==>
==> eth0 [ 172.16.0.1.255.255.0.0] ==>
host-1 eth0= 172.16.0.2/255.255.0.0
==> eth1 [ 172.17.0.1.255.255.0.0] ==>
host-2 eth0= 172.17.0.2/255.255.0.0
==> eth2 [ 172.18.0.1.255.255.0.0] ==>
host-3 eth0= 172.18.0.2/255.255.0.0
Thanks in advance for any guidance you can give me.
Johnny
