I am trying to set up the DMZ in ooma and it does not seem to be working.

I have a server that has a webserver and ssh server running.

Here is my setup with IP addresses:

Cable Modem


Internal Network = 192.168.2.x

I have Ooma dmz set to and vonage dmz set to

Everything worked fine before I inserted the ooma device. Does the dmz work on the ooma device?

You could connect your Ooma device behind (on the LAN side of) the router, connecting your router back to the Modem. Than your servers will function as before. Connect nothing to the Home port of your Ooma device.

Try it.

Some people have Ooma Quality of Service problems with the Ooma device connected behind the router, but most don't.

If you do have QoS problems, post the problems and someone will give instructions how make corrections.

If you don't have enough LAN ports in your router, you can purchase and install a good "Switch" which will mulitply your ports.

Good Luck!

After much consideration I decided to put my ooma hub on one of the 4 ports on my FiOS router, but nothing behind the hub. The down side of this is I can't access the setup page of the hub (or the telo if that's what you have) via it's IP (, but this is easily overcome with a bit of port forwarding (via a one-time connection to the "home" port).

I did this because I wanted the hub to be on its own, and I did want my network going through a device I did not know that well. Since I have a fast Internet connection, I was not too worried about QoS and the hub's ability to throttle my network's access to the Internet.

With ooma side-by-side with the rest of my network, I have no problems. It sounds like this might be a good option for you too, since you have a network a tad more complex than most.
