I'm not sure how big your subnet net to be but
ifconfig eth0 10.0.0.1 netmask 255.255.255.0 boardcast 10.0.0.255 gw
(your public ip)
should make that work with the server
Computer wireless 10.0.0.4
10.0.0.2 (wireless) 10.0.0.3
ComputerA ----- HUB --------COMPUTERB
|
|
Gateway Server 10.0.0.1 eth0
public ip eth1
A--ifconfig eth0 10.0.0.2 netmask 255.255.255.0 boardcast 10.0.0.255
route add -net 0.0.0.0 gw 10.0.0.1
B--ifconfig eth0 10.0.0.3 netmask 255.255.255.0 boardcast 10.0.0.255
route add -net 0.0.0.0 gw 10.0.0.1
C--ifconfig eth0 10.0.0.4 netmask 255.255.255.0 boardcast 10.0.0.255
route add -net 0.0.0.0 gw 10.0.0.1
now everybody should able to ping each other then
setup firewall rule and masq you are good to go.
