Saw this method to add a second router on Verizon FIOS

"The coax is actually an output, and goes in to the coax splitter which provides guide data and On Demand/Interactive content to the STBs.

You need to have them enable the Ethernet feed from the ONT (if you haven't already). But you need to do the opposite of what joelusi said above. Start by factory resetting the Fios router. You will not be using the Bridge mode (doesnt work anyway for what we need). Keep the Fios router the primary router (without that you will lose On Demand, remote DVR control, and guide data). Take your secondary router and make sure it has a DHCP range different than the Verizon (you wont need that Verizon router network- its only for the Fios boxes, and you should disable the wireless). Connect the WAN of your router to a LAN port on the Verizon router. Then in the Verizon router, open the DMZ to the secondary router you are using. This will allow you to keep the guide data, On Demand, and Remote DVR functionality, and still allow you to access your secondary router/equipment via VPN, DYNDNS, etc.

We do this on all our Fios installs and have Pakedge behind the Fios routers. As long as Verizon doesn't get involved on a support issue and reset the router you're good to go. Always keep a backup of the Fios router config file just in case you do have to get the router back to what you need in a pinch.

Keep in mind if one of the routers has already pulled a WAN IP and you are swapping to another router, you MUST release the WAN IP then immediately disconnect that router. If you try swapping routers without doing that, the new router will NOT pull a new IP- it is bound to the old router MAC address. Only way to release the IP is to wait 4 hours with nothing connected or call Verizon. Easy enough to release the IP beforehand in the connected router to avoid that issue."

If you had a business with static ip addresses, would this method still work? If not do you know a method to add a second router to Fios?

You can turn things inside out. Connect your router to the ONT, then connect the WAN port of the Verizon router to your router. You'll still get the Guide data.

So connect the ONT to the WAN port on my router then connect the WAN port on the Verizon router to a LAN port? Do you also still have to reset the DHCP on the Verizon router?

You may need to reboot the Verizon modem. Be sure to turn OFF the Verizon wireless and don't connect anything to the Verizon LAN ports. MOCA support will still be active on the Verizon modem.

And, as you have said, you need to acquaint the ONT with the new router.

I'm not exactly sure what you mean by "multiple static IP addresses". If you mean fixed IP addresses on the LAN side, this is a function of the router. You can reserve IP addresses on the Verizon router. If you mean that there are multiple WAN IP addresses, I don't think that the ONT supports this.

Thanks you you were allot of help

I dug around a little and it seems that you can have multiple public IP addresses available through the ONT.

I did not find a step by step setup discussion and there is no one and only way to do this. Here is one link that will get you started. You can search for "Multiple FIOS public IP address" and dig up some additional information. Maybe there is a step by step discussion out there, but I did not come across it.

Wow! Thanks for sharing this, rwaterfield! I may have to try this out some other time. :)
