Problem regarding QoS

    I play lots of game, so I have to open lots of ports in the QoS (my friend insists on having a QoS). Is there a limit to the amount of port you can open per rules? Or a maximum number of rules? Ever since I added a few, it's been giving me logs of
    Aug 18 02:15:48 tomato_s user.crit init[1]: Error while loading rules. See /etc/iptables.error file.
    Aug 18 02:15:48 tomato_s user.info rcheck[16481]: Activating rule 0

    That's not normal, not at all.

    After much testing, I discovered that each QoS has a limit of 15 ports or port ranges. Now, my question is would having a lot of QoS rules slow down the system? (Making it slower to respond to requests and such.)

    QOS = Quality Of Service. It is a way to slow down certain types of traffic. It sounds like you should leave QOS turned off, and use port forwarding to open ports in the firewall. If you use DMZ instead you would open all ports at the same time.

    I know what QoS, and it's working (limiting all non entered traffic and torrenting traffic, giving higher access to port 80 and all specified ports (mostly games).) The thing is, I wonder if having a LOT of different rules (have about 12 right now, 2 of which is filled with 15 ports/port ranges) slow down the port handling in anyway? I am asking this 'cause my roommate thinks that if I open give access to all these ports, the QoS will take more time to give the accesses to the ports. I told him it didn't work like that and it shouldn't cause any slow down, but I do want a clear answer on that point.

    Anyone?

    Another way to fix the problem is to give everything high priority by default, and create rules to slow down the bad traffic. What kind of traffic do you have on your network that you wish to keep slower than port 80 and the games ?

    Ok, short question instead.
    Will having about 15-20 rules (some with lots of ports) in the QoS slow the connection down because it would have to look longer in the QoS port list to give attributes to each connections?

    I don't think so.
    logically, once the connection is classified (trough its port), the QoS only have to balance the bandwidth.
