[luau] RoadRunner or EarthLink?

[R. Scott Belford]

When back in Georgia earlier this year, I helped a friend set up his
earthlink dsl connection.  It is important to note that the DSL modem
used by earthlink is actually a router.  It holds the public ip address
and issues a 192.x.x.x address to your computer(s.)  They use pppoe and
the router cannot be altered to operate as a bridge.  I believe that
earthlink is only offering cable service here so far, so this point is
currently moot.

On the subject of cable/dsl modems being routers: During the last few
months, all of my dsl orders with Verizon have been set up on ATMs
rather than Frames.  Verizon has also begun issuing Westell 2200 modems
with new orders whether you are your own ISP (our case) or if you are
using someone else.  The 2200 modem is different than the previous 2100
series because it too is a router.

Out of the box is set up to work in a pppoe environment, it is set up to
handle NAT, it has a web server (this is how it is configured), it can
be a DHCP server, and it has a configurable firewall that creates logs. 
It is dangerous.  It can configured to act only as a bridge, but this is
not the default setting.  Username = admin, password = password, or was
it admin?
