Cisco PIX and router question

Last Modified: 2010-04-17
Is it possible to drop the inside link on the PIX if the outside link fails?
I wondering as i wish to have something similar to the diagram below... where their will be a secondary WAN link that will take over if the primary one goes down.
I need the router to know when the primary WAN link goes down, as i will have 2 default gateways set up with metrics favouring the primary route. when the line goes down the second default gateway will jump into place.

    WAN LINK 1 - - - - - - - - - outside(PIX)inside - - - - - - Router- - - - - - LAN 1
    WAN LINK 2 - - - - - - - - -  - - - - -- - - - - -outside(PIX)inside


If anyone has a better idea of how to achieve what i want?
