Bridge Mode on X5001 Modem

We're on fiber and have the X5001 modem. The signal is weak in several parts of our house, so we added a Google Nest mesh network. That got the signals and speeds up very nicely.

It created a double NAT though, which created conflicts with a number of our smart devices. I also need port 80 open on one computer. Following the tech notes provided by Xfinity, I switched the modem to bridge mode and out internet ran better than ever.

BUT, as it turns out, this modem can't handle the TV boxes if it's in bridge mode so all of our TV boxes were showing errors. The only way to have TV is to take it back out of bridge mode and go back to the original set of issues. Turning off wifi on the modem doesn't 

Apparently this is the only modem that has such a limitation, but it's apparently the only modem we can use since we're on fiber. How can I resolve this?

You can do what's referred to as "Poor man's Bridge Mode": Assign your Google router a reserved IP, and put that IP in DMZ. This will give you a psuedo bridge mode but allow your TV boxes to continue to function as normal.

Thank You!!  I was hesitant to give it a try but it worked like a charm.

The X5001 has wifi turned off with a reserved IP assigned to the Google router which is connected by Ethernet. I applied the DMZ as you suggested too. TVs still have their MoCA connections and I'm now able to set the port forwarding through the Google router.

I have, just, unpacked my Google Nest to mesh my network - hopefully to get WIFI to my second floor.  Please explain how to Assign your Google router a reserved IP, and put that IP in DMZ.   Thank you.

@user_5613aa​ You will need to do the following steps:

Local Admin (10.0.0.1): Log in (default should be admin/password or admin/admin, you will need to set a new admin password, so do so.). Go to Connected Devices, find your Google Nest router if it's connected, and select "Add Device with Reserved IP". You can also use this option and manually specify the MAC address of your Google Nest. Make note of the IP you've assigned to your Google device.

xFi: Tap/Click "View Network Details".

If you're on the xFi app, tap on "Advanced Settings", then "DMZ". Tap Edit. Check the box to enable DMZ, then specify the IP address you reserved for your Google device.

If you're on a PC browser, Click/Tap on "See Network" at the top, then go to Advanced Settings, then DMZ. Click/Tap Edit. Check the box to enable DMZ, then specify the IP address you reserved for your Google device.

And that's all there is to setting up psuedo bridge mode (or Poor man's bridge)
