MetroNet Optic Fiber Input a router that is routing traffic?

I have connected the Core to my Metronet Ethernet Cable via the WAN port of the Core. The Metronet Ethernet Cable is connected to a special wall outlet that connects to the Metronet Optic Fiber Network.

All other connections are made through the LAN Ports and the Wi-Fi Networks of the Core.

The Security Section of the App denotes that I have a Double Network Detected issue. In Red letters it states "Core has been connected to another device that is routing traffic". Can the Core detect such a device through its LAN Ports and/or its Wi-Fi Networks? Or is it wrongly flagging some code incoming from the Optic Fiber connection?

Thank you for your time. (The App Version is 1.25; the Firmware Version is 171130_213.)

Ole Jerry. The short answer to your question is YES! Core does indeed detect double NAT setups.  Is the wall outlet a small fiber optic converter similar to this? If so its the cause of the notification you are seeing. Its normal and nothing to worry about.

There is a internal line that leads from the wall outlet to a box in the garage labeled "Cyber Power" which might be a converter.

If it is normal, then why doesn't the Core treat it as such, and not issue a security remark that confuses me. It does affect my security score. What is wrong with a "double NAT setup" to the end user who cannot do a thing about it?

Thanks for you reply.

Re: MetroNet Optic Fiber Input a router that is routing traffic?

The double NAT warning is due to having a device such as in my setup, my FIOS router. The FIOS router for me MUST keep its DHCP or routing active due to my TV & VOIP phone services to function. Therefore it has its wifi turned off and cannot be set in bridged mode to prevent the NAT-NAT warning.

NAT-NAT means two devices are routing traffic at the same time. So there is nothing WRONG with a NAT-NAT setup, its just the Core letting you know it exists and there are possible solutions such as putting your modem/router in bridged mode. Since you have direct fiber there is no modem or router to configure. Core sees the converter as a routing agent and reports it as NAT. Hope that explains things for you adequately.

Re: MetroNet Optic Fiber Input a router that is routing traffic?

Thanks for  your explanations

However, I still feel, for we users having an Optic Fiber provider, .that the message given- ("Core has been connected to another device that is routing traffic") is confusing, and really should be suppress. Who thinks of a provider as actually a device routing traffic. AND to where? Can the provider route traffic from me to my next-door neighbor?

Maybe on detecting the.NAT-NAT setup, the App should have an option (for user choice) of specifying possible sources causing the NAT-NAT setup in the App Setup Screen/Window. If we choose, for example, Optic Fiber Provider, than the App would suppress the Setup error message; thus not lowering our Security Score.

If the Core and App could actually denote the source of the NAT-NAT Setup, and if it were an Optic Fiber connection, automatically suppress the error confusing message, more power to it.

Re: MetroNet Optic Fiber Input a router that is routing traffic?

OJ please remember that the security score is just that. Nothing more than a score and will always be different with every network configuration. And no, your traffic isn't being routed to a neighbor. When a optic service comes into a dwelling it is in the form of light which must be converted into a digital format for networks to use. The box you have wherever it may be does that. Core detects it as it would with any routing / converting device that is the first device in the network with routing capabilities. Thus the NAT-NAT. Its not warning you that something is wrong per se, but rather stating it cannot protect that upstream routing. From the Core and throughout the remainder of your network Core 100% detects and protects it. I have NAT-NAT setup here and am perfectly confident with it.

Re: MetroNet Optic Fiber Input a router that is routing traffic?

I know that my traffic is not being routed to a neighbor!!! I could not show sarcasm in my remarks here. (g)

Well, you might be comfortable with the handling of your System by the Core. But I am NOT!! There is no reason why a confusing security setup remark is shown in this instance for something I have no control; except maybe changing to an internet provider not having optic fiber. Optic fiber is the current trend that some providers are initiating. I would think that the Norton Core Developers would notice this new trend.

I was suggesting ways for better handling this issue for us having Optic Fiber to the Norton team; which evidently is not present here.

Again, thank you for your input. Your initial explanations were informative.

Re: MetroNet Optic Fiber Input a router that is routing traffic?

Lol!! Sarcasm accepted. Just trying to be nonsensical and to the point to give the best info possible. I hope in a future firmware release most, if not all the small quirks are added or deleted as applicable. I DO know the core threads are monitored by Norton and they ARE taking notice. Changes just don't come overnight as we'd all like due to the matrix companies have to follow for those changes. Your setup is a good one other than the annoyance you have with the NAT-NAT notification. Unfortunately that is the way things are baked into Core in its present form. I'm hoping to have answered your questions as thoroughly as possible and you will remain a Core user as I am. Have a great day today!! And a happy holidays as well.

Re: MetroNet Optic Fiber Input a router that is routing traffic?

Thank you for your kind remarks. Hopefully any quirks will be ironed out. I feel safer with the Core than any previous setup I have had. (Now, if we could also have a Web-based connection to the Core, that would be "Icing on the cake"; if you like Icing. (LOL))

You also have a great Day!! Oh my, back to Christmas shopping!! (lol) You also have a Blessed Christmas Season.

Sincerely

OJ if you believe we have answered your questions please mark the thread as solved if you'd be so kind. Others can then see the solution when having a similar issue. Thank you for those kind words as well.
