Config is a definite requirement as lrmoore has asked, but please can you also post a description of what you're trying to achieve?
Here is sample IOS commands that works for me.
You will have to modify IP address that have "<>" around them.
**************************
interface Ethernet0
description Link to External Network (Internet)
ip address 216.123.201.161 255.255.255.0
ip access-group 120 in
ip nat outside
no ip route-cache
no ip mroute-cache

interface Ethernet1

ip address 192.200.202.254 255.255.255.0
ip nat inside

ip nat pool USERS <External NAT IP> <External NAT IP> netmask 255.255.255.248 This can be the same as the External IP.
ip nat inside source route-map natpool pool USERS overload

access-list 110 permit ip 192.200.202.0 0.0.0.255 any
