Is eth1 connected directly to a modem, or one of these pervasive
'modem/router' combos? In particular, did you have to configure PPPoE
on the server to achieve that connection? (In ubuntu, I believe, you
would use pppoeconf.) Since this is a server connection, you don't want
it managed to network manager, which is only meant to be used as client
connections, and I have no idea how it would mangle a PPP connection.
