I have setup my Ooma device (Telo). I have a Cable Modem / Ooma / Router


Cable Modem: 65.184.x.x
Ooma : 172.27.x.x
Router: 172.27.x.x

The DNS for my website is pointing to the IP of my cable modem. The problem is that the Ooma is not passing that IP through to the Router so my services are being blocked and the Ooma is setting the routers IP of to it's IP scheme.

How do I configure the Ooma to pass my Cable Modems IP through the Ooma so I can access my Webserver using the DNS of my domain name?

I'm thinking the Ooma needs to be setup as an Access Point?

Change Ooma from Automatic to Use DHCP.
Change Ooma to use built-in MAC address.
Set the starting IP address for the Ooma DHCP server to issue at
Set the ending IP address for the Ooma DHCP server to issue at
Set the Ooma DMZ IP address to

Turn modem, Ooma, Router off.
Turn on modem and wait for sync with ISP.
Turn on Ooma and wait for boot up completion.
Turn on router.

If you have DynDNS enabled in your router, disable it and install the recommended DynDNS client software on your computer.

Brilliant! I was on support for over an hour and they had me disconnecting items and was unable to resolve this issue.

Thank you, it worked like a charm...
