[plug] ADSL failover

[Simon Scott]

	no pppoe?

	How does it work specifically? How does the modem connect to the
box?

	Is it static IP?

	I use iinet ADSL, and it hasn't gone down since i had it put in in
May. They use

	Telstra but do it in a different way to Telstra. They don't use
pppoe or
	anything, your link has an IP address - and they give you an address
for your
	box, and that is it. In my opinion a much cleaner system.
