I have a serious issue and haven't been able to resolve it. Whenever I start torrents, other traffic (TCP) is impacted with or without QoS (on the upstream). Setup and Facts: ----------------- 1) With Tomato 1.19, disconnection occurs after a few minutes 2) With Tomato 1.23, disconnection occurs after a few seconds 3) Torrent software is capped at ~ 200 connections, DHT disabled, 10k/sec upstream and < 200k/sec downstream. 4) Line connection is 7000kbps/500kbps 5) QoS settings: Enable Qos x Prioritize ACK x Reset class when changing settings x Default class: Lowest Outbound: MaxBW = 460 Highest 80-100 High 10-100 Medium 5-100 Low 3-100 Lowest 2-95 6) Since the default class is lowest, I've setup rules to tag specific traffic as highest, high, medium and low. 7) Congestion control enabled or disabled (same problem) I've confirmed that the traffic tagged at a higher priority is indeed identified and tagged. However, whenever I start torrents, that traffic is still impacted. My upstream usage is also quite far from the maximum BW so I have no idea why my other traffic is dropped when torrents start. Can anyone help?
