Hello

I have a Linux Server CentOS 6.3 that has multiple network cards and 10 IP Public, and 10 NIC is connected to the internal network

Now I want the each IP to be forwarded to a client in each network
For example:
IP1: 91.166.22.11.77 Public

NIC1: 192.168.7.1
Client1: 192.168.7.2

Now I forward all ports from IP1 to Client1
In addition, all clients can Internet access via dedicated IP

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


Thanks for your help

I think you will need nat: https://en.wikipedia.org/wiki/Networ...ss_translation (if I understand it well)

I want configure this:

tap_soft > eth0:0
tap_gw01 > eth0:1
tap_gw02 > eth0:2
tap_gw03 > eth0:3

and I can forward every request from eth0:0~3 to one client in tap_gw network...

I really appreciate..

No one in this world answer me.............???????
