Google Wifi and Verizon FiOS

Avoiding Double-NAT, but keeping On Demand, TV Guide, etc.

You essentially want to reverse the order where instead of going Verizon -> Google -> Devices you want to make Google the primary router and Verizon a sub network. Here's how:

1. Connect the ONT (ethernet handoff) to Google router (WAN)
2. Contact Verizon and have them switch from Coax to ethernet handoff
3. Plug Google Wifi LAN into switch
4. Jump from switch WAN port of FiOS router and that will create the LAN (double-NAT) for your FiOS TV boxes. 
5. Leave the coax connected to the fios router.

Then only the cable boxes will be on a sub net and everything else on your network will be on the Google router.
