2. eth0 - outside ip address private (10.0.0.2)
eth1 - inside ip addresss private (192.168.0.1)
Correct answer. Your modem handles the external assigned ip address , it has an internal local address to which you connect eth0 , your firewall is set up to route all traffic from your eth1 intranet (192.168.0) network to eth0 after processing thru the firewall rules. Should all work
Now comes the tricky part, setting up the firewall. Don't forget to make your firewall accessible to your intranet if don't want to havea seperate screen attached to it.
