Identity NAT on router

Hello Experts,

Please help with below scenario:

 

Background:

I need to configure NAT on a C3900 router to retain original IP address (referred as Identity NAT in firewall).

 

Scenario:

There is an existing configuration to perform unconditional NAT, and that's causing a hindrance for a new connection. The ways to overcome it (as per me) is to convert the existing config to "conditional NAT" using route map (needs downtime as its in production) or instead configure a new NAT statement with identity NAT; not sure if this concept works in IOS.

example:

ip nat inside source static 1.1.1.1 1.1.1.1 route-map temp-test

 

Appreciate your help. Thank you in advance.
