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.
