Ok here's the deal. Internet --> Cable Modem --> Vonage Router (192.168.15.1) --> Wifi Router (192.168.1.1) but wifi router is assigned 192.168.15.2 via Vonage Router Which fucking port/ip do I need to add to the DMZ/ip forwarding to raise the telephone quality? I have a feeling the answer is going to be "None idiot, the telephone line is not part of the network it's parallel and since Vonage is not behind another router there's nothing you can do but raise the QOS via Vonage" ... but I'm just not sure. Thanks fyi: the issue I'm having is the new fax machine can't connect and I need to raise the quality for the phone and lower the connection speeds of the fax (which I did)
