I just set up an Ooma Telo a couple of days ago. The installation went smoothly and quickly. My setup is a Motorola SB6120 (modem) to Ooma Telo to AirPort Extreme Base Station (AEBS). With this setup I received a message from the router (AEBS) regarding a double NAT situation, which I told it to ignore. Everything is working fine, but from the research I have done a double NAT situation can cause problems and I will lose some functionality so I would like to eliminate it. As I understand it there are two ways to eliminate the double NAT. The first is to place the Telo behind the AEBS. Although I have a fast Comcast connection (16Mbps down and 3 Mbps up) I would prefer not to do this to ensure the best possible voice quality. The AEBS doesn't have QoS features so I have to use the Telo for this. The second option is to add the AEBS IP address assigned by the Telo in the Ooma setup DMZ field. I think I would like to do this, but have read conflicting information on the internet about the implications of this. On the one hand, I read that enabling the DMZ option will allow the Telo to perform QoS while allowing all inbound traffic to pass through to the AEBS - in other words, my router would function the same way it did before I installed the Telo. On the other hand, I read that enabling the DMZ option will make my network less secure by opening it up to the internet somehow.
Can someone with far more networking knowledge than me explain the implications of enabling the DMZ option? Specifically, will this in any way reduce the security of my network?
Thanks, Scott
