I have some difficulties in understanding how Tomato QoS works, basically regarding inbound QoS. To setup QoS I need to classify my traffic. The page for configuration of classifying rules is entitled "Outbound direction". But what about inbound traffic? How can I classify that? Inbound traffic is not always initiated by an outbound connection. Voip RTP streams are initiated from the outside. How can I classify them? Is there some good documentation about Tomato QoS settings? The polarcloud FAQ and the Tomato wiki are very rudimentary regarding QoS settings.
