Ok, but the question is if a packet from Internet can reach my Real_IPs
that are behind the firewall? That is, how the linux box knows that a
packet from External IP to Real_IP7 has to travel eth0 -> eth1 -> hub.
ROUTER----------(eth0:Real_IP2)- Linux ------
(Real_IP1) | |
(eth1:Real_IP3) | | (eth2:Internal_IP1)
| |
----------------
| HUB |
----------------
| | | | | | | |
(Real_IP7)
