Mike,

Do all 20 interfaces have a different hostname in your DNS?   Do you have
your machine checking /etc/hosts first, then DNS?  If both are true, try
putting all 20 interfaces by the same name in your /etc/hosts then
demandpoll the router.   NetView should then give you one object with 20
interfaces.

Kind regards,
