NAT will try to use the same address pair (in this case, destination IP) for the same source address, in fact creating a not-so-round-robin. Splitting it up into multiple DNAT rules makes it a true round-robin. -- 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
