Ok.. I posted this on Vonage forums.. Thought I'd try here to see if anyone can give me any insight.. I recently replaced my Vonage Motorola TA with a new PAP2. I couldn't get it working behind my Linksys WRT54G router. The PAP2 worked fine hooked directly to my cable modem. I got it working by reseting all my settings in my WRT54G router to default. So I knew one of my settings must be screwing up the PAP2. I enabled things one by one and figured out the solution. If I enable QOS by MAC address using Linksys original or HyperWRT firmware, then the PAP2 won't connect to Vonage thru the router... Is this normal? Should I take it back to Bestbuy and try getting a new PAP2? QOS works if I use port based QOS, or if I load Alchemy firmware on my WRT54G. Also... my Old Motorola worked fine with MAC address QOS.
