Nat on MSFC's

Unanswered Question

I work for a large health organisation and we're currently finishing off a restructure of our VLANS and IP address, migrating from B-Class 172 to C-Class 192.168 networks.

However as we have a large number of integrated clinical systems we can't get our suppliers in to re-integrate all systems on one day, and as such i'm looking at doing NAT on our MSFC's.

Does anyone know the commands required and ACL's if required for me to change a system and have some systems acessing the migrated machines using the new address, while unmigrated machines are still acessing via the old address still. I've tried standard ip nat inside but am unable to get it to use the nat address, only the real.

Any help is much appreciated.

I have this problem too.
