Here you've hit the key... "or stateful firewalling". Stateful firewalling provides the security. NAT just mangles the header. Overloaded NAT depends inherently on the stateful firewall and this has lead to confusion where people don't realize that the term "NAT" is often (mis)used to refer to the combined process. Owen
