I'm a little confused.  My ISP (AceDSL in the NYC metro area) uses, I
believe, 1483, and I need no extra features to have my fbsd system talk
directly to the dsl modem (Westell) over ethernet with no extra protocol
layers and full 1500 mtu.  I have a static IP address and a /29, and just
need a default route to the ISP router's addr.  The dsl modem is acting
as a bridge, not a router.  The routing and firewalling is done by my
fbsd system.

Are you talking about running the phone line directly to the fbsd box
with no dsl modem?
