Try connecting it up behind your existing router, and see if it connects and works. I used to have a Vonage device, and it did the same exact nonsense, yet it still worked fine when behind the NAT in the main router. The web server and rest of the networked devices all still remained connected to the original router. You may need to forward some UDP ports, such as these from the OOMA website, UDP 1194,UDP 3386, UDP 3480, UDP 10000-30000.


Whenever I needed to configure the Vonage, I had to connect a notebook to the Vonage Ethernet ports to gain access to the web server port.
