This is the only way this will work if the customer has TV service. Others have tried numerous options to figure out ports etc to forward and it doesn't work nor is it worth the effort.
Every Fios install is done as stated above.
If you want to move the Fios router to the rack you can. That is where mine typically are or in a wall cabinet in the equip room.
1) Plug an Ethernet from Fios Router into Wan of your router. 2) Let your router pull a dynamic IP address from Fios Router. 3) Go into Fios Router and go to advance settings. I do a DHCP reservation for the IP address of your router listed. I then change the IP address to 192.168.1.2 (Fios Lan is always 192.168.1.x) 4) On Fios Router Go to firewall settings on and put 192.168.1.2 in the DMZ. 5) On Fios Router Go into WiFi Settings and turn off 2.5 and 5ghz radios. 6) reboot your router to ensure its pulling the new IP address. 7 You are done.
Double Nat is not an issue. Now if Fios Router craps out, which eventually it will, the customers will loose internet access but their internal network will be running just fine. Just happened to me on a new install. Customer got a Fios router that died within a month. Then have to rinse and repeat steps 1-5.
