If all else fails, create an regular (upload) qos rule for Netflix, throttling it, BUT use the internal interface(s) of the UTM, as the source parameter, and the client network(s) you wish to throttle it for as the destination -- and place the rule on the internal interface(s) of the utm. It's sort of an upload QoS rule in reverse... it will work, I've done it before (assuming application control is detecting Netflix traffic correctly -- I'm not aware that it isn't, but one poster here has said it isn't working right). This is what I used to do all the time before we had download throttling. Squeeze the pipe on the other side, the flow will slow on the internet side [:)]

Tried that Bruce. Does not work I think because the proxy is acting as a client buffering full speed from the Tinterweb then trying to serve to the LAN throttled.
My next throw of the dice is to disable IDS, Web and App proxies so it is basically just a router, and try what you suggested to see if that works.
I don't know enough about this stuff, but presumably we cannot control a TCP stream by the window/ack mechanism can we? That would mean having the QOS mechanism embedded in the TCP driver, wouldn't it? Be awesome if we could because then we could throttle any TCP stream in the download direction on the external interface without losing a single packet or forcing a re-transmit.
I was going to use the 1k subnet that Netflix's content servers are on in Europe to do my "application recognition". Think that may work but trying to find a 1 hour slot to do the watching of another couple of episodes of Breaking Bad (while working this issue of course).
