I used this guides as a guide lines but, streamlined it a bit. I swapped the mac addresses only. What this did was create a serparate subnet within the network of my new router. The new subnet only contains my STB’s. I simply plugged the WAN of my new router into the FIOS equipment. I plugged the WAN port of the router into an ethernet port of my new router. The new router served up an IP the verizon router. And everything just worked. I was even able to order pay-per-view.
