Well, the fix was quite easy. I forgot to remove the IP address from the
ethernet interface before assigning it to the ELAN and bringing up that
interface. Using the command
ifconfig tu0 delete [my-ip-address]
..before ifconfig'ing the ELAN interface did the trick.
Thanks to Laurent Deniel <deniel_at_worldnet.fr> for that tip. I know this
gets said a lot, but this list is a wonderful asset. Less than an hour
later I got an answer from someone in another part of the work.
