Nat configuration issue

I did this wrong buy I'm not sure how to correct it.

[code:1]!
ip nat inside source list LAN_RANGE interface Serial0/0/0 overload
ip classless
!
!
ip access-list standard LAN_RANGE
permit 192.168.0.0 0.0.0.255
![/code:1]

Here is the full configuration of router 0:

I should point out that aside from private addresses being able to get past wan links all other devices are perfectly functional.

Glad these boards are slow... I would have robbed myself of a chance to figure it out. I was looking in the wrong place.
