I was assuming you would configure it to know what local addresses are rather
then expecting it to work them out. So many sites use sub-netting and run
several sub-nets on one ethernet (we do), that determining the "local"
addresses is non trivial. A list of networks/netmasks together with a list of
router MAC addresses should be sufficient.
