Hi Everyone. I followed the sticky (https://forums.verizon.com/t5/Fios-Internet/Using-your-own-router-with-Verizon-FiOS/td-p/851632) on how to use your own router while using the Fios router to keep VOD, DVR, etc. I was successful in releasing the DHCP from the Fios router, connecting my Eero router to the ONT, and getting internet.
Where I messed up was connecting an ethernet from the Eero LAN port to the Fios router WAN port so that I can still get VOD. I thought I changed the subnet on the Fios router to be on the same subnet as the Eero router (192.168.4.x), but I guess I did something wrong. I couldn't get On Demand to work (timed-out error) and I couldn't log back into the Fios router using 192.168.1.1 or 192.168.4.x. As a result, I had to reset the Fios router. I was able to access the Fios router using 192.168.1.1 and the PW that's on the sticker. I turned off WiFi and I disabled DHCP. I didn't change the IP address prior to the disabling the DHCP. Everything works - internet, Fios TV, on demand, DVR, etc., but I can no longer log back into the Fios router using 192.168.1.1.
So couple of questions:
1. How do I know my set-up is correct where my primary router is my Eero router and the Fios router is only used for MoCa for VOD, DVR, etc.?
2. What should I do about the Fios router and how it's set up? It my network double NAT'd?
Thanks!
