IP Forward Or Packet Forward

BaTa

Hello

I have a Linux Server CentOS 6.3 that has multiple network cards and 5 IP Public, and 5 NIC is connected to the internal network

Now I want the each Public IP to be forwarded to a client in each network

For example:

IP1: 138.166.161.77 Public IP and forward to a client1

NIC1: 192.168.7.1 Private network

Client1: 192.168.7.2

Now I want forward all ports from IP1 to Client1

In addition, all clients can Internet access via IP Public 1

What IPtables command should I write until ports forward from each Public IP to each Client on private Network...

Please Help Me...

WAN interface:

eth0:0

eth0:1

eth0:2

eth0:3
