## PPP
## ===
##
## A PPPoE (PPP over Ethernet) configuration to address the case where
## your Liminix device is connected to an upstream network using
## PPPoE. This is typical for UK broadband connections where the
## physical connection is made by OpenReach ("Fibre To The X") and
## common in some other localities as well: ask your ISP if this is
## you.
