Short answer OttFibe is yes.
Without knowing the ins and outs of your rig, this is how i got it to work.
On the Bell router, I had to have both the TV side and the Internet side of the modem logged in. My Linksys router is setup to connect PPPoE like I had it with my old slow mow modem.
This is the only way that I could give full functionality to all the Bell things on the Fibe TV and I still have direct connection to the internet.
