Yes. You need to use extended access-lists in conjunction with route-maps.
route-map nat-map permit 10
match ip list 100
!
access-list 100 permit ip any 125.10.1.0 0.0.0.255
!
ip nat pool nat-pool 72.10.1.1 72.10.1.100 prefix 24
ip nat inside source route-map nat-map pool nat-pool
I'm doing this off the top of my head so please excuse errors, but this is the basic idea. Anytime someone on your network tries to get to 125.10.1.0/24, they will be NATed to 72.10.1.1-100.
Corrections?
