Port forwarding talks of ipchains firewall.
But is it not that ipchains comes into effect only for packet filtering.
that is, only after the packet reaches a network interface, the rules
will be checked to decide whether the packet is to be accepted or denied.

How do I decide which network interface to send the packet to depending on
whether it is a mail or another protocol packet?
