NAT does not do forwarding, and neither does Netfilter - routing will. The multiplexing you want is probably best done with a program that does just that - think of sprucing up rinetd. -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
