We have a situation where hosts from several different networks are passing through a router for traffic shaping. The networks may be, e.g., 184.108.40.206/24, 220.127.116.11/24, 192.168.1.0/24. We are using pcq's such that each host gets an equal share of the available bandwidth. With v4.x the system worked well.
After upgrading to v5.6 and with the default values for the new parameters "Src Address Mask" and "Dst Address Mask" in Queue Types left at 32, the traffic was not limited any more. The question then is what is the exact meaning of "Src Address Mask" and "Dst Address Mask" and what values should we set in our case?
