IPTABLES PAT

A Simple PAT / Port Address Translation for outgoing traffic:

1.    Remove any existing user-defined chains in the NAT table, reset the default policies on all chains, and flush all rules:

        iptables –t nat -F

2.    Configure NAT using Iptables (In this example eth0 is the public outgoing interface)

    iptables –t nat –A POSTROUTING –o eth0 –j MASQUERADE

  2. For point 2. The command '#lokkit' can be used too. it provides a command Line Base Menu. which can be used to set NAT and routing from one network card to the other if need
