You can bridge the Fios Quantum Gateway Router

Question

 Long story short. I could not figure out how to disable SIP on the Fios Gateway Router and some my Intercom Video Door station in use by my Control4 uses SIP. The router was causing conflicts and Control4 advised that SIP needs to be disabled on the router. Disabling SIP is a very common answer to people using IP based video conferencing or VOIP phones. That left me with 2 choices. Get the Fios Quantum Gateway to bridge and install my own router where SIP can be disabled, or get rid of Fios and use an ISP that does not require a combo "modem"/router. I didn't want to give up on Fios so easily. My installation was new and I am happy with the uptime and performance. I spent 2 days trying to get my Fios Quantum Gateway to Bridge.   I am writing this up so that someone else doesn't have to live the pain I've lived.  First up, after multple days of looking, their are limited instructions on getting the Fios Quantum Gateway router to bridge. The instructions you can find are for the Actiontec router. It's "almost" the same router but not 1:1. Most step by step guides say that the steps for the Actiontec will work for a FIos Quantum Gateway. That's not inaccurate, but isn't fully accurate either. Their are steps involved in the Acitontec instructions that do not apply to the Fios Quantum Gateway. First - this link is the baseline instructions I found that mostly work: http://www.dslreports.com/forum/r27666920-How-to-Make-Actiontec-MI424WR-Revision-I-Rev-I-a-Network All credit to the authors that came before me. I didn't discover these steps. I hijacked them and tested them with some revisions for a Fios Quantum Gateway router. I take not credit or responsbility for any action you take based on my post. It "works for me" and continues to work after 24 hours. My please note that I am using Coax/MoCa from the ONT to the Router and that Ethernet was not an option. I am going to repost the steps verbatim, but add some notes along the way where my experience was different in bold. I highly recommend you read the entire thing one time before starting with the step-by-step. You can replace the word Actiontech with Quantum Gateway in the below. Their are subtle differences in termonligy between the Acitontec and the Quantum. If you see a step in the guide and can not follow because your Quantum doesn't have the same display, you must find the nearest equivelement or ignore it entirelly. First get your Router and Actiontec set up like so: ONT -> Coax -> Actiontec Coax Port -> Actiontec LAN Port 1 -> My Selected Router WAN Port. Unplug the cable from the WAN Port, but keep it nearby. I was actually in LAN Port 1 on the Quantum Gateway but I don't think it will actually matter.
Now we need to obtain the WAN MAC address of each Router device.
For the Actiontec go to: Top Menu – Advanced – MAC Cloning – Set Mac of Device – Broadband (Coax). Here you should see the MAC Address, write this down on a paper or something. This is critical. You need to do this. Without the clone, I was unable to bridge. Note that I did not have to STAY cloned. I just had to clone until the lease expired even though I believe I had released the IP successfully. For your own router: You need to look this up yourself. The ASUS RT-N56U (w/ custom firmware) has a spot that just displays my WAN MAC address for me. I'm using an EdgeRouter from Unfi. Nobody can help you here except the forums for the router you are using because how you do this is different from router to router (generally speaking.)
Once you have both of these pieces of information, it is time to start.
1. Hardware Reset Actiontec Router I wouldn't do this. I didn't. I would actually save a copy of the configuration you have on the router before going any further, in case you have to hardware reset and restore your router.
2. Log into Router using [ admin/password ].
3. Change admin login info and set a different password. There should be a link on the side.
4. Top Menu – My Network – Side Menu – Network Connections – Network (Home/Office) – Settings – IP Address – Setto 192.168.x.1 where x is not used on your LAN – Apply
*NOTE*: Upon changing the default gateway IP of the Actiontec from 192.168.1.1 to 192.168.x.1, you will need to [ ipconfig /release ] and [ ipconfig /renew ] from Command Prompt, so your computer can quickly reconnect to the Actiontec. I changed this to 192.168.0.5 because my DHCP starts at 50. The Fios default is 192.168.0.1 and not .1.1.
5. Log back in to Actiontec router with new IP and new password you previously set.
6. Top Menu – Wireless Settings – Side Menu – Basic Security Settings – Wireless Off – Apply 7. Top Menu – Firewall Settings – Side Menu – General – Minimum – Apply
8. Top Menu – My Network – Side Menu – Network Connections – Advanced 9. Top Menu – My Network – Side Menu – Network Connections – Broadband (Coax) – Settings – Release – Apply
*NOTE*: If your IP address is not released properly you will need to wait 2 hours for your lease to expire or you’ll need to call Verizon Tech and get them to restart your system.
10. Broadband (Coax) – Settings – IP Distribution – Disable – Apply 11. Broadband (Coax) – Settings – DNS Server – No DNS Server – Apply 12. Broadband (Coax) – Settings – IP Address – No IP Address – Apply
13. Top Menu – My Network – Side Menu – Network Connections – Network (Home/Office) – Settings – IP Distribution – Disable – Apply 14. Network (Home/Office) – Settings – DNS Server – No DNS Server – Apply 15. Network (Home/Office) – Settings – UNcheck Box to Left of Wireless – Apply
*NOTE*: The old guide will tell you to uncheck the box to the left of “Coax” here. Unfortunately, in the Rev. I, Ethernet and Coax are stuck together as “Ethernet/Coax” and you can’t split the two. If you uncheck the box to the left of “Ethernet/Coax”, you will lose connection with the Actiontec Router and you will be forced to hard reset and start all over again.
16. Network (Home/Office) – Settings – Check Box to Left of Broadband (Coax) – Apply 17. Network (Home/Office) – Settings – Check STP Box to Right of Broadband(Coax) – Apply The Quantum Gateway didn't have an STP box to uncheck. I ignored this step with no adverse effects. 18. Network (Home/Office) – Settings – Network – Broadband Connection – Apply
19. Top Menu – Advanced – MAC Cloning – Set Mac of Device – Broadband (Coax) Using the information you gathered at the beginning: a. Set the WAN MAC of your selected Router to the MAC address listed here. b. Set the Address here to the WAN MAC of your selected router that will be connected to the Actiontec to avoid conflicts.
20. Plug the cable from Actiontec LAN Port 1 to your Routers WAN Port. Your router should be getting a WAN IP from Verizon. Test to make sure your WAN is established and that you can connect onto the internet, browse pages. Run a speed test to make sure everything is peachy.
*NOTE*: If your router did not get a WAN IP, you have a problem. I would recommend trying to re-trace your steps to see if you missed anything or just start all over and hard reset. :\
21. If everything worked out fine, connect a cable from your Router’s LAN Port 4 to the Actiontec LAN port 4. Again, I was using Port 1. But it shouldn't matter. I haven't tried other ports.
22. Power cycle your STB if you wish. You should see your STB show up in your DHCP list and it should be getting VOD/Widgets. This wasn't neccessary for me as I don't use Verizion TV service. Your millage may very. -V

Answer 1

NOTE: about bridging the Quantum Gateway G1100 Information about this is in DSLReports.com - Verizon FiOS FAQ.  SEE: Verizon Online FiOS FAQ -> 3.2 Moca -> Can I get an ethernet connection in a room with only coax? There is a list of instructions for bridging routers, but the Verizon Quantum Gateway is not included there. Follow down the instructions and at step 2.5 here is added information that is not in the FAQ yet. 
Instruction 2.5...
2.5a) The Verizon Quantum Gateway G1100 is slightly different from the Actiontec MI424wr. If your primary router's broadband connection is provisioned over coax, you need to disable the remote router's coax WAN connection to prevent it from attempting to become the primary router. If your broadband connection from the ONT to your primary router is ethernet, this step may be unnecessary.
Click on the MY NETWORK icon at the top.
Select NETWORK CONNECTIONS from the menu on the left.
If you’re using the Verizon Quantum Gateway G1100 as the remote router the Network Connections panel will show Broadband Connection (Ethernet/Coax) instead of Broadband Connection (coax).
Click on Broadband Connection (Ethernet/Coax)
The next panel displays Broadband Connection (Ethernet/Coax) Properties as its title. There is a Disable button at the top of the panel. There is also a Settings button at the bottom of the panel. You will come back to the Disable button.
Click on the Settings button.
The next panel displays the same title as the prior panel: Broadband Connection (Ethernet/Coax) Properties
In the middle of the panel next to the heading Enable/Disable Coax Link: there is a button labeled Disable.
Click on Disable.
Click on the Apply button at the bottom of the panel.
You will be taken to the Broadband Connection (Ethernet/Coax) Properties panel that you saw before.
At the top of this screen there is a button labeled Disable
Click on Disable
Click on the Apply button at the bottom of the screen.
