Indeed, networks with some kind of anchor point (even xDSL networks with a LNS that terminates PPP sessions) really lend themselves to a big fat NAT box simply because there is a single point where all the connections appear anyway so why not have a single box doing NAT/DPI/etc as well? I'd agree that, usually, distributed is better but these are not distributed networks, there is a single point (or a few large single points) of contact. -- Leigh ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
