For NAT to work the packets must travel from an interface labeled as an "inside" interface to an "outside" interface. In your case it sounds that the e0 interface has only an "ip nat inside" command, I'll assume and the e1 interface does not have Nat configured. If traffic goes in between either of those interfaces then NAT will not change any addresses.
