[Cialug] Century link fiber

I opted to buy (not rent) the Zyxel C3000 when I signed up, just to have
something that was a 'supported' modem/router, but I leave it off and use
my own.  With gigabit fiber into the home they just plug in the Ethernet
from the fiber box, which there is no added charge for.

Like Rob I took all the settings out of their modem and programmed them
into my Ubiquiti router.  VLAN 201 + PPPOE user & pass is the gist of the
settings IIRC.

If I ever have any issues (I haven't yet) I can plug in their modem and
call up support.  Plus it acts as a backup/spare should I have a Ubiquiti
issue.
