NAT is of two types:a)Static and b)Dynamic. Since you want to use two private ip addresses internally you have to configure DYNAMIC NAT on your cisco router.Access lists are also to be configured as a part of NAT process.Following commands are to be given in order to configure the Dynamic NAT:

1. enable

2. configure terminal

3. ip nat pool name start-ip end-ip {netmask netmask | prefix-length prefix-length}

4. access-list access-list-number permit source [source-wildcard]

5. ip nat inside source list access-list-number pool name

6. interface type number

7. ip address ip-address mask

8. ip nat inside

9. exit

10. interface type number

11. ip address ip-address mask

12. ip nat outside
