Making IPS and Verizon FiOS ONT co-exist

Verizon offers fiber-optic Internet to the home.  Having been very bitter with the poor back-end support of Roadrunner's, Timer Warner's, Comcast's and AT&T's high-speed service, I immediately leaped into and signed up for a 2-year contract after selecting Verizon's FiOS 3-Play option.

Verizon technician installed a neat white box, which now sits in the corner of the basement.  The white box has a name; it's called ONT, or Optical Network Terminator.  Fiber cable ends there and it comes out a sweet bliss called INTERNET.  If you selected phone option (part of FiOS 3-Play), you would get a battery backup, (also entombed in a white but much smaller box) affixed next to the ONT.

All of above, this was some 3 years ago.  Life was good;
