Now that you mention it, neither do I. I certainly don't remember
putting it there. Would that perhaps be a Linux module or a Debian
package that could have put it there? Is there a database of all such
interfaces explaning their meanings, usages and origins?

Hmm... since this is a machine to be used by a layman, I guess I should
do something to make pon do that by itself. Perhaps a script in
/etc/ppp/ip-up?

I guess not, because that notebook will be used now and then on
Ethernet... or will poff kill the default route when needed?

I guess not, since I don't quite get the concept! :-)
Thank you for your attention!
