What made me write the previous post was this excerpt from the
route manpage:

route add default gw mango-gw
       adds a default route (which will be used if no other route matches). All packets using this route will
       be gatewayed through "mango-gw". The device which will actually be used for that route depends on how we
       can reach "mango-gw" - the static route to "mango-gw" will have to be set up before.

which seems to imply that the existence of an interface does *not* imply
that packets for the corresponding network are routed to it. Nor, IMHO,
should it - you still may want to route some destinations on that network
via an other way, for whatever reason.

Ciao,
