Assuming, for example, that the machine with 2 NICS is set up as follows:

1. Enable IPv4 forwarding (option in linuxconfig or YAST setup or, in a 
RedHat type system, ensure the string "FORWARD_IPV4=true" exists in the 
/etc/sysconfig/network file.)
2. hub NIC address is 192.168.1.1 and network is 192.168.1.0
3. private network to machine 6 NIC address is 192.168.2.1 and network 
address is 192.168.2.0

Then:

on the other hub machines (with addresses in the range 192.168.1.2-254), 
execute:  "route add default gw 192.168.1.1"

on machine 6 (with address in the range 192.168.2.2-254), execute:
 "route add default gw 192.168.2.1"

Voila.
