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: 91.166.22.11.77 Public forward to a client1

NIC1: 192.168.7.1
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

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


Please Help Me...

eth0:0
eth0:1
eth0:2
eth0:3
