Devices listed on my gateway wifi do not match devices in my xfinity application

So I wanted to setup port forwarding. I logged into my router via https://10.0.0.1. When I go to connected devices, it correctly shows just my one device (a unifi gateway). When I try to setup port forwarding, it says I have to do it in the xfinity application. When I go to the xfinity app, I see a long list of devices (9), and none of them are my device. So I cannot setup Port Forwarding in the application, because my device is not listed. To me it seems like I'm showing someone else's account info. I went ahead and "Paused" those other devices, but somehow I feel like I just disabled someone elses internet. I have my wifi turned off, and am just using the wired connection, so I know it isn't other people connecting to my wifi.

Perhaps your neighbors are inadvertently connecting to your network / gateway device via the MoCA feature that's built into it. MoCA (Multimedia Over Coax Alliance) is an alternate hardwired way to connect devices to a home network if ethernet cabling can not be used/run. It uses the existing coax cable wiring instead of ethernet cabling.

If the MoCA feature is enabled, and you do not have a PoE (Point of Entry) MoCA filter installed on the coax line, yours, and your neighbor's gateway devices will be able to connect with each other like one big network.

Disable it if you aren't using it. If you are, install a PoE MoCA filter on the input port of the first splitter off of the street drop to keep the MoCA signal in your premises and to keep the neighbor's signals out. Your neighbors should also have PoE filters installed.

To disable MoCA on your device. First, unplug the coax cable line from the jack on the gateway device. Then go to the gateway login http://10.0.0.1

Default login info is:
Username: admin (all lowercase)
Password: password

Once in you will find the drop-down on the left of the screen that is labeled “Connections”.

Click the drop down---> click MoCA---> right side of screen click “disable”---> save changes.

Bear in mind that we've seen many posts here that the MoCA feature gets turned back on with their overnight re-boots / updates for the device. The best policy is to be sure to use that PoE filter ! Amazon has them: https://www.amazon.com/SNLP-1GCW-Filter-Eliminate-Multi-Room-Interference/dp/B07SLD9QPH

Or you may be able to get one for free at your local Comcast / Xfinity store. Or book a tech to come out and install one for you.

If the MoCA feature is not being used on your home network, you can put the PoE filter right at the back of your gateway device instead.

I ran the MoCa Diagnostics, and here is the result. It was already disabled.

MoCA Diagnostics

Status:Disabled

MAC Address:(redacted)

Maximum Version Supported:2.0

Current Operational Capabilities:

Preferred Network Controller:No

Active Network Controller:Active

Backup Network Controller:MAC: (redacted), Node ID: 0

Beacon Frequency:

Center frequency:

Beacon Backoff Power Level:0dB

Link Uptime:0d:0h:0m

Number of Packets Transmitted:0

Number of Packets Received:0

Number of Uncorrectable Error Packets Received:0

Number of Corrected Error Packets Received:0

Channel Mask:00003FFFFFFFC000

Privacy:Disabled

Also, when I ran the diagnostics, it said no MoCA devices connected. The output is a little confusing as it says disabled, but enabled for Active Network Controller, and there is a backup controller listed.

What I find concerning is that my device is not listed in my xfinity app.

So I feel stupid, but I don't need the Xfinity gateway port forwarding if I put the modem in bridge mode, since I have my own router. However, it is still concerning to me that the devices do not match what was in the gateway.

Hello @user_5fxj6y, Thanks so much for taking a moment out of your day to leave a post on our community forum, and we would be happy to help. Please make sure you're following these directions:

xFi users: Set up port forwarding - Add a port forward with an xFi Gateway

Open the Xfinity app and sign in with your Xfinity ID and password.
Select the WiFi tab.
Select View WiFi equipment.
Select Advanced settings.
Select Port forwarding from the menu.
Select Add Port Forward.
Note: If you've previously set up a port forward from your Gateway's Admin Tool (http://10.0.0.1), you should see it listed in the Port Forwarding Settings.
Choose the household device for the port forward you're setting up from the drop-down list of connected devices.
Note: If you don't see the device listed, it may not be connected to your home network.
Choose from the list of common applications to use a recommended, preset configuration (e.g., Xbox or PlayStation) or select Manual Setup to enter specific port numbers, ranges and/or protocols.
Select Apply Changes to complete the setup of the port forward.
The device you set up for this port forward can now use these settings.
Note: If you're unsure which port settings to choose, reference the device manual or the application you're trying to use.
Opening unnecessary ports isn't recommended, as it may pose a security risk.
