I have been researching this for a few days and still cannot get a simple NAT to work. We need to access a server but have overlapping IP's in our networks. Do I need "one-to-one" NAT statements? Does this require an ACL and or Route-map?
Goal: NAT 4 IP's.
10.1.29.1 NAT 10.52.100.1
10.1.29.2 NAT 10.52.100.2
10.1.29.3 NAT 10.52.100.3
10.1.29.4 NAT 10.52.100.4
Gig0/1.52 - Inside facing users on 10.1.29.0/24: ip nat inside
Serial1/0 - Outside towards server: ip nat outside
Switch --> Router (NAT) --> MPLS Network --> Server
