Oh right, I've started graphing this and noticed its not that much different
from the amount of data going through the tun0 interface :(

Ahh right, no worries.  I think the modem is connecting @ ~40k then training
down pretty much immeadiatly or within a 5minute period as speeds are
generally quite good to begin with then drop to miserable 2.5/3k.  Since BT
came to install xDSL and said pretty much the line wouldnt support it
becuase of noise now I'm determined to at least have a usable modem line.
I'll find a another way to batter BT then, has anyone had any experience in
forcing BT to do something about a crappy line ?
