Yet another QoS Thread

    Hi everyone.

    I've been over the QoS FAQ and threads. I understand the classification rules, As they are similar to my previous software QoS system (cFosSpeed). What i don't completely understand is the basic page settings.
    Could anyone try and explain some of the details and classing?

    Just as a note, I'm on an L2TP cable connection, 1.5mbit down and about 128kbit up. I'm mostly trying to shape HTTP downloads, BitTorrent (µTorrent) and DCC (IRC transfers), With certain game ports taking precedence over those.

    Any help or clarifications on the options would be appreciated.

    Unless you want BT to take over you entire connection, I would leave it as the low priority catch all rule. The only entry that really require any alterations are the Outbound Limit, and Inbound limit (although inbound isn't really used)... if you want to control inbound you might want to look at the script build applet. As for Web, IRC and L2TP you might want to set up port based classification, avoid the L7 filters as that don't tend to be very effective.

    This is what i have now. Upon turning it on, BT's download stream was cut by half. Am i missing something obvious here? The L2TP connection seems to be on port 1701 UDP, but only between my cable modem and ISP gateway, And isn't caught by the rules for some reason.

    Attached what i have now.

    Here is my basic setup... I have tweak it slight as I have added FTP, etc.

    I have since added a catch all for ports < 1024 for medium priority

    I'm more interested in help with the basic page settings, If you could. As far as i understand it, My rule list is OK - But that doesn't explain the reduction of BitTorrent download speed when QoS is turned on.

    Have you verified with your chart details that all bit torrent connections are classified as lowest ? If the upload rate is sufficiently attenuated it can slow down the inbound rate to values lower than what you have set, which looks to be what is happening with your setup. If all BT is in the lowest classification, try setting inbound and / or outbound for lowest category to 100% for testing to see if the speed resumes.

    Edit - When I want to fine tune a particular type of traffic I assign it to a lettered category. You can assign Bit torrent to class "E" to better isolate it from other traffic and make it easier to adjust.
