Query on QoS

    I've setup QoS with the MAC address of my Asterisk box (which is also assigned Static IP at Highest priority. The QoS rule works very well for traffic orignating from the asterisx box to my VoIP Service providers (CallCentric and Brain.net), which get allocated Higest priority. However, traffic from to the IP of my WHR-HP-G54 router all gets allocated to Unclassfied, which I've set to be "Low".

    The question is, do I need to worry about internal traffic b/w te Asterisk server and the router?. If so, how do I go about doing it?.

    UDP	1552	RizSher.RizSher (		53	Unclassified
    UDP	1547	RizSher.RizSher (		53	Unclassified
    UDP	1550	RizSher.RizSher (		53	Unclassified
    UDP	5060	alpha2.callcentric.com (	5060	Highest
    UDP	1553	RizSher.RizSher (		53	Unclassified
    UDP	1551	RizSher.RizSher (		53	Unclassified
    UDP	1549	RizSher.RizSher (		53	Unclassified
    UDP	1554	RizSher.RizSher (		53	Unclassified
    UDP	5060	chat.brain.net.pk (	8891	Highest
    TCP	1214				1403	Lowest

    QOS only works on traffic that goes out through the WAN interface. All internal traffic remains unclassified and is not subject to your QOS rules. Unclassified is not the same as the default classification (which you've set at Low) - if something is Unclassified, it has not been (and will not be) subject to QOS at all.

    There are ways of doing QOS-esque things on your internal network, including Wi-Fi Multimedia (WMM - http://en.wikipedia.org/wiki/WMM ). As far as I know this is not implemented in Tomato though.

    what? WMM is not in Tomato? Are you sure? I though it would be standard on ANY firmware

    It is there.....there is an option under Advance->Wireless for WMM to be enabled

    Are you sure?. My understanding, and ofcoruse it could be totally incorrect, was that you any traffic that doesn't hit one of the rules setup in QoS, get assigned the "Default" class. The default class in my case is Low, so all Unclassified traffic would be set to Low?

    Pretty sure, yes. What would be the point of classifying LAN connections as 'Low' if they are never going to be examined by the QOS algorithm? Remember, QOS works to maximise the efficiency of your WAN upstream. LAN connections will never pass through this bottleneck, so they are irrelevant as far as QOS is concerned.

    Your statement is true for WAN traffic - all WAN connections should be classified. WAN connections not falling into any of your defined rules will be classified as 'Low'. In contrast, LAN connections will not be classified at all - hence they are shown as 'unclassified'.

    As for WMM, there does seem to be something labeled 'WMM' in the advanced wireless options, but I don't see any detailed configuration like in DD-WRT (IIRC it is not trivial to set up correctly). Here's a description of the WMM config in DD-WRT:
