Multiple ip addresses with hardware router

[Tony Baechler <tb@baechler.net>]

Hello all.  This is my first post to the list, so sorry if this is off 
topic.  I have a Dlink di604 hardware router.  I am running Debian 
Woody.  Is there a way I can get Linux to listen to multiple ip addresses 
(not the internal 192.168 block, but in the 68.x.x.x block)?  Does the 
hardware router block all but one ip address or is there a way around 
this?  Thanks very much.
