I have been playing with a dsl/ppp connection for a couple of days. I am
not sure I need a redundant failover though... I can make it work
manually if I need to.

I did:
ifdown eth0
ifup ppp0
to switch from dsl to ppp, and have commented out the "auto ppp0" line in
/etc/network/interfaces.

You may want to confirm that "proxyarp" is not enabled in your ppp
configuration... (?)

I don't think you want to set the network data here.

I don't know about "No network protocols running" but you need cooperation
with the other end of your connection to set local:remote.
Make sure you have all the needed ppp modules loaded, and determine
whether you need "auth" or "noauth".
