nat problem with cisco 8100 router

[dlc]

I need help with a NAT problem with a 8100.  I have 3 of these units and one stopped working so I bought a replacement.  I set the new one up exactly like the others.....the only difference being that the new one did not have a NAT tab in the web gui setup whereas the others did.  I did go into the console and issue the ip nat inside command to the FastEthernet port and it seemed to take.  But I still cannot pass traffic to the outside world.  It appears to me that the 10.10.10.x address is being passed instead of the ip address for our company.  I cant verify that but that is my gut feeling as the setup appears to be correct. 

Any ideas where to look next???

that was supposed to be a 881 router  not a 8100.
