I don't think that this will work at all. From what the tech's have told me, and what I've read about the MoCA technology is that it uses unprovisioned bandwidth from the ONT using the MoCA protocol in order to provide video services to your motorola boxes. Otherwise, you'd be sharing your 5 mbit or 15 mbit or 30 mbit connection with 2-10 mbit of video, and that wouldn't work very well at ALL.
As far as I know the only way to get verizon FiOS TV is through the MoCA trash Actiontec. There's a reason I had them install via ethernet, and why I still have DirecTV HD. I pole-mounted a DirecTV slimline 5 LNB dish outside my house so if at some point in the future verizon decides to get rid of the crappy MoCA actiontec non-sense I can switch over. But until they do, the actiontec router is a deal breaker. I refuse to use it, it's just plain crappy in 500 different ways. It locks up, has a small state table, is slow, and unreliable.
Besides, DirecTV has more HD's anyways, and is about to pwn't the HD cable/sat industry once their next 2 birds go live. (excuse the shameless plug)
I'm currently running with a cisco router for my house internet, but trying to get pfSense to work. Apparently the DHCP client portion of pfSense is either currently broken, or the mac address cloning in combination with DHCP doesn't work.
