QOS Port and/or Netmask

    I realize this could be an Alchemy or a DD-WRT question, as it is probably the same answer for both. I haven't been able to find a good answer to this.

    I am using DD-WRT with QOS only to make sure my Vonage PAP2 for VOIP doesn't have quality problems.

    I have the PAP2 set up with netmask priority of Premium.

    The only other thing that is set up by default is port based priority. It looks like the default for DD-WRT is that Ports 1-4 all have Premium port based priority. Port 1 is my VOIP. Port 2-3 are just PCs.

    Should I change Ports 2-3 to Standard or leave all the ports 1-4 as premium?

    I guess I'm unsure about how port and netmask work together for QOS. The help file says they work together somehow, but doesn't go into details.

    I believe the port qos is hardware based and is done inside the cpu, whereas the netmask qos is done via software, i would set your port to premium, but for added reassurance set your netmask to premium also.

    Ok.. I have them both set for Premium for the VOIP adapter but what about the other ports? Standard or leave them as Premium.

    If I have everything set as Premium, then doesn't that negate the QOS? Or if I have Premium for a netmask and don't list any other netmasks, does that assume that every other netmask is standard? And then since I'm using netmask, the Port based QOS is ignored?

    i think, and i'm not on solid ground here, that the port based QOS gives precedence to the Wired ports over wireless, or one particular wired port over the others. you can just set the other wired ports to standard or bulk, i have mine set like that; although i use L7(service) based qos too.
