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.
